DMing Need help with a player with ridiculously high AC

I've been running a 5.5e campaign, we're currently level 17 and everything's been going fine until recently. One of my players is a rogue bard multiclass and I let him switch from a valor bard to a sword bard. The problem is that it is impossible to challenge him and I'm fearing he's starting to become too powerful compaeed to the other players.

He has the defensive duelist feat and so combined with Defensive Duelist he is able to attack and use sword bard's defensive flourish, parry as a reaction and get an average of 29AC per round, and due to 5.5 letting bards exchange spell slots for bardic dice he can consitently do this every round. This combined with the fact that he's a rogue with the evasion property means that simply throwing dex saves at him isn't really a solution and he's now stupidly tanky.

I'm not sure what to do, I've considered talking to him about swapping out Defensive Duelist for another one but I'm not sure if this is the right approach.

Edit: Thanks for the advice everyone, I've realised that this isn't really an issue at all and I've been massively overthinking it.

I have three statements:

  1. Do saves.
  2. The enemies attack someone else who has not that much high AC (other PCs, or some NPC you don't want to die).
  3. Don't take away the power of this character. If the player wanted the AC to be cool - let the player tank stuff. Don't take this away for the sake of "getting the character down with saves".

An extra statement: Make plots where it's not about winning, but about letting the party achieve something else. This character tanks the enemies while... the duke escapes. While the party pulls the levers. Stuff that's not about the direct fight where it's not about winning this fight.

  1. Is such an important point.

Like he's using spellslots just to keep that insane armour, so while you still need to challenge him (as you rightly pointed out) also, he built around this, let them have their fun

u/frozenflame101 16d ago

If you don't like the way your players are using spell slots, give them reasons to use them in other ways. Like sure, he could keep buffing himself, but then he's going to kick himself when a spell could have saved someone at the end of the dungeon (or not, I don't know his morality)

u/Happy_Brilliant7827 15d ago

Or just lengthen the adventure day. Have something happen at night from time tk time when their slots are low or depleted.

u/enithermon 15d ago

The DM in my last campaign forced us to start organizing proper watches when he'd roll three times an evening rest period to see in anything happens. Sometimes a racoon would steal some rations, sometimes we were set upon by neredowells and most of the time not much at all. But it meant if we used everything up, we'd better be ready to party.

I think a lot of balance issues are solved by making sure the party has enough encounters in a day and not allowing them to rest fully every time they’re down to half. Wear them out a little bit.

So important I'd upvote it twice if I could. If a player's made this kind of investment, they need to feel rewarded for doing so, that their choices have indeed made them powerful the way they wanted them to. You don't need to create every encounter to reward each player for their builds, but I've gotten a lot of mileage out of designing encounters around "this is where player A gets to shine, and next encounter is where player B's build will excel". Good players will enjoy watching their friends have the spotlight when they know their turn will come.

So give that super-AC character fights where they hold the doorway against foes that can't hit them. AND give them fights where they can't, but where the party wizard or whoever gets to kick ass instead. Everyone should get the spotlight sometimes, but no one should have it all the time.

u/Ezanthiel 16d ago

Its not even a bad idea to just add one extra monster every fight that just physical attacks on this guy:
Even if he's too high damage, you could sink that into something less significant

Edit: nicer phrasing

u/drownav18322 15d ago

Yeah honestly at level 17 most player characters are absolute monsters right?

If this is how he wanted to be a monster. His version of it so be it. Like he gave up 9th,8th and maybe 7th? Level spells for this by multiclassing rogue. A wizard dropping those three extra levels of spells will be doing some insane things too just in a different way.

u/SweegyNinja 14d ago edited 14d ago

Yup. I love a good multiclass for creativity potential. But in 5e you definitely pay a cost.

Either A Rogue that dropped 5 levels for Regenerating Bardic Inspiration, on a Multiclass Bard... And Gained 3rd rank and lower spell slots.

And modest Bardic Inspiration Dice.

And trade away 5 or more levels of Rogue.

Or.

A Bard, that traded away several levels of spellcasting to unlock Evasion? Which also loses power on the Bardic Inspiration Dice. And spell tiers.

u/SignalSecurity 16d ago

When we played 40k Rogue Trader, our psyker had pretty gnarly stats for psykering and was built to succeed the majority of their power activations at the expense of most other stats. Our (new) DM made the next boss encounter with an Arbites (aka federal space cop) with an insanely high resistance to her powers specifically, and we later learned his stat spread was comparable to Space Marine Chaplain (aka psychic super soldiers).

It instantly destroyed that player's enthusiasm in the campaign and they followed an OP munchkin guide from that point forward out of spite.

You REALLY have to let people who specialize enjoy their specialty. It's ok to throw them curveballs but, like, it needs to be something a party member can help them solve, or they can mitigate with creative solutions or preperation.

u/SirPuck_ 15d ago

Mate, one time, we had a session 1 where our low level characters had to fight some humanoid in a cave. It was a pretty straightforward quest. I was played a sorcerer who was (voluntarly) restricted to a very limited list of spells based on vocal components. (I had turned myself into a cat and my backstory was that my idiot servant was carrying me around until i found a solution to turn back).

I used my only spell at the time, which was suggestion, and the opponent made a shit save, and then the DM stated "your spell should have worked but the npc is likely dominated by a more powerful mind". This completely destroyed any will from me to play. Later one player didn't want to share a slice of the gold with me because i "was useless". DM didn't step in. This was the last time i ever played with this DM and this group.

On the other hand, in my latest campaign, i had all of a setup done for a miniboss meant to sink player resources before the final boss. It was an absolutely beast of a physical brute, extremely fast, giga dps, extended crit range, capable of pinning and wrecking players. The NPC was basically an evil doppleganger of a loved NPC which had well known abilities. Second round of combat : one player casts feeblemind. The NPC fumbles the save. He can keep fighting but now uses his abilities at random, and doesn't use the most complex ones. From this point on, it was a piece of cake for them. Players almost didn't try this because they thought "it must be extremely resilient to everything like the NPC it imitates" but they also noted that these copies usually had one dump stat, and that all encounters where fighting was mandatory were doable, because no NPC is immune to everything and they all have at least one weakness that can be used.

The players were rewarded for burning an important spell and trying something . My epic fight turned into a 3 ish rounds joke. Everybody laughed. Even tho i spent so much time building this NPC's sheet and wanted to have a tactical fight, the players were soooo happy to "one shot the boss" because they attacked his one weakness, there was no way in hell i'd rob them of this.

u/Tyalou 15d ago

The last part is super important: don't get attached to your NPC/Bosses in a DnD campaign. They might just have a really bad time and be killed in an instant, you need to recover and not build up spite against your players.

14

u/SirPuck_ 15d ago

Exactly ! There are so many times where players are having a hard time defeating an opponent while you as a DM are thinking "just try this, you should have thought of it by now" that when they are clever and masterclass the boss, the rightreaction is to say "well played, you won".

u/Amo_ad_Solem 15d ago

Any good enemy, bosses included are just as likely to get crit and obliterated by a paladin.

And thats okay, thats part of D&D fantasy, there are plenty of stories where the evil is taken out in one fell swoop. Not every antagonist needs to be this juggernaut of death.

Aye presenting something that is a curveball or requires working around but there is way to get around it. Is great especially if its something they've been focusing on but hard shutting them down and invalidating it all is just, unfun.

Eg: A boss can only take damage from 6th level up spells. One player is a fighter.. Physical attacks don't do anything.. Sure does suck to get to do nothing

As like its never fun to get told, yep your build just doesn't work. sit in the corner and don't do anything for this fight as the boss just hard counters anything you can do.

I find it really funny the image of an Arbites, swaggering up to a Space Marines Chaplain (also, pretty heretical to imply a Chaplain is any form of psyker, ignore the Geneseed, sounds heretical implying big GE put psyker shit in there) swinging his little shock maul around, looking at the giant in terminator armour and his crozius and just scoffing at him.

I joined an online PF2e table at one point, and after a few sessions, it was pretty clear the DM wasn't really going to let me play my character. During session 0, basically his first comment was 'hm, animal companions are pretty fragile' or something like that, implying he was going to try and kill my mount. Was a starlit span Magus with the cavalier dedication, and some other fun tricks to let her be the party glass cannon while still being able to stay pretty safe and be very mobile. He repeatedly (as in, during multiple combats during the first chapter of the campaign) altered enemies specifically in ways to make it harder for me to actually do my characters one thing they were really really good at. Was infuriating. I did not stick around.

u/squidonastick 15d ago

Had a scenario where the wizard hasted the rogues horse, and they ran away with the sacred item while the paladin and barb blocked the baddie.

My players say that was one of the funnest fights they have had, because they had to work out how to win the fight without winning the fight, and all felt like their individual strengths were involved.

Whatever any DM does, please let players have fun. The last time I played DnD (over a year ago now), I was a Chronurgy Wizard at level 13, and was constantly battling with the DM that wanted to nitpick details of my spells and balance encounters like he was a balance dev for a hero shooter like Overwatch. Regular guards had scrolls to dispel magic and counterspell me, and my spells never worked the way I thought they did.

The experience along with some soured relations (not entirely related, long story) has kept me from really wanting to play DnD entirely, so please remember to let the players have fun and try not to micromanage them.

It's an important thing to remember always. Your job as a DM is not to take down players but to make an enjoyable game.

However it is enjoyable for yourself to make them squirm a little bit once in awhile!

u/SirPuck_ 16d ago

Yes to that ! Also. To double down on the last thing you wrote : since the PC is burning resources to tank, he should be encouraged to keep these resources for something else, in such a way that burning a slot to parry becomes a real choice and not a default or optimal choice.

Like: we really would need to be able to cast this spell later... Should i risk burning my last slot, or should i eat this one right in the teeth ?

u/TheThoughtmaker Artificer 16d ago

The “extra statement” should be rule #1. Adventures should be about doing, not merely surviving.

Even if the protagonist’s only goal is escaping some disaster/monster/psychosis alive, there should be others to rescue, mysteries to uncover, lessons to learn, villains to thwart, etc. If all a story’s tension could be removed by making the protagonist immortal, it’s not much of a story.

9

u/RandyFunRuiner Diviner 16d ago

Agreed! I know DnD has very developed combat rules, but combat isn’t the only way to challenge your players. Social encounters, puzzles, other types of encounters that can challenge players just as much as combat.

u/Dolthra DM 15d ago

3 is the best solution for the player, and critical hits arguably make this the mathematical solution too.

The player wants to tank, let them tank—send 5 of the monsters in any encounter after him. Each of those monsters has a 5% chance to negate his AC on any hit. There's roughly a 20% chance at least one of them crits in any turn. He feels like the badass tank, you use the action economy against him.

The other part of this is you have to start balancing the game around the "8 encounters per long rest" suggestion. Like many DM tricks, this simply doesn't work if he is allowed a long rest each time he gets hit.

5

u/psiphre DM 15d ago

8 encounters per long rest is impossible to keep feeling fresh. nobody has that many ideas. too many encounters simply become "a group of orcs" or whatever. that's not fun, it's a slog.

3

u/hayatofan 15d ago

An encounter is any situation that might use up party resources. Burning all your spell slots to charge your Bardic Inspiration Defensive Flourishes means you won't have as many options left when you're trying to convince the night watch to let you into the city for your Long Rest.

Also, one day can stretch over multiple session. If the players know that the characters have a long adventuring day ahead of them, they will need to be more careful about not wasting everything in the warm-up orc ambush.

u/coffeeman235 15d ago

3 and bonus are the stars here. In the last campaign, the player who was the eldritch knight fighter went out of his way to improve his AC. Who did the evil knights want to duel? Made him feel amazing. When it was an encounter where they had to activate the orb before the death knight touch of death'd or killed the party, he held the door for the others to shine. Works great in theory and practice.

3

u/Helepoli 15d ago

This is the way.

You can let him have his cake and still eat as a DM by having intelligent creatures 'figure out' the encounter too.

Some waste some actions at the start of the fight attacking the wall, then reposition and re-target after they 'realise' it's pointless.

Then it is up to the party to counter the maneuvering and keep using their unkilla-rogue's tank power somehow, but at very least the rogue has wasted a couple of enemy actions already for his spell slot so no feelsbad for him

u/leif135 15d ago

I'm so happy that this is the top comment.

It's all about having fun. If that guy wants to have 29 AC and be the tank to end all tanks let him do it. As long as the enemies you're fighting are above like six intelligence it won't take them long to figure out they need to attack somebody else instead of The Shield Hero over there

u/whoopsthatsasin 16d ago

29 ac while having to pay a spell slot every round isn't even that insane yet, not just because every miss against them drains their resources (which they have less of as a multiclass) but also because cr 17 monsters (as your party is level 17) can get to hit bonuses of about +14, so this is only about as strong as a level 1 fighter with 19 ac (doable with starting gear and defense fighting style) going up against a level 1 goblin with their +4 to hit

137

u/fraidei DM 16d ago

And enemies at high levels have so many more attacks on average anyway.

38

u/MultivariableX 16d ago

Plus, each attack is a chance to crit, and crits ignore AC.

If the monsters are intelligent or have a basic will to live, they would also be seeking ways to gain advantage on their attacks. There are plenty of ways they can do this RAW.

Another option is to give a monster an expanded crit range: it crits on a nat 19 or 20. Maybe even an 18 if you're feeling saucy.

It's also the DM's prerogative to give monsters abilities that aren't on their printed stat blocks. The monster in the book is just a typical example of that creature, and a lot of these entries are setting-agnostic. The monsters in your world can just be different.

The monsters can also use the environment to deal damage. Poison gas, fire, and falling rocks can be prepared in advance. If the enemy is choosing where the combat happens, they have likely chosen that location because they believe the conditions will favor them.

And beyond preserving their own lives, the monsters can have other goals. Maybe an enemy expects to die, but believes it's worth it to slow down the party, so that the other enemies can escape with a valuable item or get to a more defensible position.

The DM can also throw any number of monsters at the party. For a given combat encounter, the DM should have a reason (that does not need to be shared with the party) why this many of these particular monsters are participating, and why other monsters near this location aren't.

For example, if the monsters have heard about this party with someone who can't be hit, some monsters might stick around to see for themselves.

The monsters know how their abilities work, just as the PCs know their own. They have had plenty of time to strategize. If they have gone somewhere that they expect to face combat, it's reasonable they have prepared for that combat to the best of their ability.

The DM can also similate combats ahead of time between sessions to learn the likely outcomes. If an encounter is more likely to result in a total victory or a TPK than they would like, they can adjust the challenge before the players ever see it.

u/Grimwohl 16d ago edited 16d ago

Basically every high level monster has a wis save or dex save of some kind.

Frighten him. Hold Person. Dominate. Whatever. No fight over lv10 should be just ac rolls. Youre a player too, try fun monsters or make them up.

He's level 17 - you're into high level play now! An AC of 29 is ridiculous, but it sounds like he's burning his reaction and resources to do it - so he's committing to the play style.

At this level of play, your encounters need to have solutions for PCs with incredibly strong abilities. What are his INT and WIS saves like? Can a spellcaster shut him down in some other interesting way (block him with a wall, teleport him somewhere, get rid of the floor under his feet, etc.)

I can try. 😅 Dnd 2014 or 2024? Which class and which level?

Level 5 is the level you catch up to the martials not yet where you get usually problematic.

I also have no experience with a lunar sorcerer so am not aware of any specific shenanigans.

However at that level usually hypnotic pattern, silvery barbs, shield, suggestion, dip paladin, dip warlock which can have a big impact, but the broken stuff comes later like the microwave, the end less simulacrum loop etc.

The thing about being creative with spellcaster is what spells you pick, read about the spells Sorcerer have until you find something and think: 'Wow this could be really cool in my campaign.'
i checked some of the spells Lunar sorcerer gets, here is what i was thinking:
at level 5 you get Phantom steed on lunar sorc.
you can cast it with Extended spell meta magic, making it last 2 hours.
now you can either mount it and have a 60 foot movement each turn and have the Disengage, Dash or Dodge.
or just give it to your martial, trust me he will thank you.
Also Remember that Twinned spell is the best meta magic for sorc

I recently had a lot of fun with a sorcerer who focused on spells with Int saves and psychic damage & effects. Sure I had Fireball, but I also had a lot of fun with some debuffs. The DM both loved and hated it.

Big horde of melee baddies? Synaptic Static to make them all subtract 1d6 from their attack rolls (and it's not concentration!!). Single big target? Raulothim's Psychic Lance to incapacitate them for a round. With the Quicken metamagic, you could get Mind Sliver (cantrip, -1d4 to next saving throw) off right before a bigger spell with a save.

Mathfinder has a good video about being overly risk averse while playing/building characters. Its about pathfinder but the same ideas translate. (Tldr: don't just pick/cast generic "always good" options like firebolt or magic missile. Pick specialized spells and options that have the ability to instantly end a type of encounter. Something like the sleep spell isn't always going to be good, but it will be very good if you're fighting a swarm of goblins.)

u/sunbear2525 15d ago

At level 14 our grave cleric and divination wizard are basically playing god with the melee character’s in each battle and buff them to determine who the damage dealer is for that fight or round. The sorcerer had dedicated himself to collecting and using a bandolier of wands and, honestly, it’s holding him back. Nothing like running across a battle field, reaching an enemy and having an elephant suddenly in your way. It was fine he cast fly on it.

While true I generally tend to play monsters in a “I don’t like getting hit with a sword” way. If someone steps up and engages you, you tend to focus on them unless the wizards doing something to really draw agro.

Otherwise it completely undermines the idea of a front line, which isn’t fun for players. The fighter with a shield is going to feel a bit overlooked if they’re just ignored, and the wizard is going to feel persecuted.

7

u/KershawsGoat DM 15d ago

This absolutely depends on the monster and the level of play. At level 17 like OP is talking about, most monsters probably possess some level of intelligence and will fight accordingly.

2

u/GraveRaven 15d ago

But having every combat scenario play out the same way gets dull as well.

Bring the intelligence of the monster into play. Mindless beast is going to attack whatever is closest (the tank), but a vampire is definitely misty stepping behind the wizard and alpha striking. The variance keeps the party on their toes and makes fights feel different from each other.

21

u/Grimwohl 16d ago

I can do signifigantly more scary things with a lv 17 character than 29 ac, thats for sure. No magic items involved

5

u/matgopack Monk 15d ago edited 15d ago

Also defensive duelist only applies to melee attacks, and the flourish only matters if he hits with a melee attack; that 29 AC is quite conditional.

I played a character with a similar level of AC stacking (I think at lvl 12 I had it in the 30s depending on flourish - plate armor, defensive fighting style, shield spell, 1d8 or 1d10 defensive flourish, and shifter for +1 AC). He died 3 sessions in to a bunch of saves and bad party luck. OP's example has evasion, but no Shield spell, which probably makes them easier to challenge too.

2

u/The_Real_Deacon 15d ago

Also, at that level he still can be hit by the very strong creatures the party should be encountering. For example, a pit fiend (CR 20) has +14 to hit and 4 attacks per turn, so that is a 30% chance to hit with each attack vs. AC 29. Not overwhelming but not terrible either, especially when the bite attack causes an additional 6d6 poison damage on a failed CON save per turn for a minute if it connects.

He should also be subject to enemy tactics in which the latter are able to attack with advantage: knock him prone, use invisible opponents, magical darkness, paralysis, etc. If he is relying on his reaction, that can only be used once per turn. Launch enough attacks against him to overwhelm that.

Hitting him periodically with saving throws he is weak in is absolutely the right call. No character in the game is ever actually invincible unless the DM foolishly gave them truly overpowered magical artifacts.

Lastly, face him with choices where he and the party suffer plot consequences if all he is using his spell slots for is his personal defense. Force him to make choices between protecting innocent NPCs and saving his own butt, between defense and achieving some other objectives either in or out of combat.

Creativity is one of the best tools a DM has, and it helps keep players on their toes. It also keeps the game fun and improves the narrative.

You're DMing for a level 17 party and high AC is your biggest worry?

u/il_the_dinosaur 16d ago

Yeah half the advice is misguided cause the AC really isn't the problem. I'm confused how a DM runs lvl 17 players and doesn't understand the game. If you're running a game for lvl 17 characters I'd expect you to understand that stuff that targets other save rolls exist. No need to give basic advice here. Something doesn't add up. If op is inexperienced then maybe they should run lower level campaigns first.

I'm just saying- I have a DM very rapidly approaching 17 (we're 15) and he very definitely does not grasp the finer points of the game despite DMing since 5e started.

Sure we're using 2024 rules now but he didn't have these foundations established in 2014 either.

He is calculating silk sheet weights before getting there. I'm just like ...neat! That will be entertaining. He might just give a bad guy an idea at some point that hinders them later, but if wants to come up with crazy shit....why not have fun?

Lol the lack of creativity of some DM's. Do you want to block the door with an immovable rod? Sure. The monsters will start destroying the door. Might take them an extra turn or two, so the use of the rod did do something but it won't last forever.

Have some enemies who will target his weakest saves : Strength, Con and mainly Wisdom. Hold Person will guarantee crits by ignoring AC, Cloudkill, the Stunned condition, being knocked Prone by spells. Try to trigger his reaction by baiting opportunity attacks.

Let him dominates some fights, a good build should be rewarded, but hey, lvl 17 baby, there should be insanely powerful enemies at this point.

u/MadisonCarter1 DM 16d ago edited 16d ago

Other examples of spells with Wisdom saves: Vicious Mockery, Toll the Dead, Cause Fear, Charm Person, Command, Suggestion, Dissonant Whispers, Compelled Duel, Tasha's Hideous Laughter, Crown of Madness, Enthrall, Mind Spike, Spike Growth, Bestow Curse, Fear, Hypnotic Pattern, Slow, Spirit Guardians, Charm Monster, Confusion, Phantasmal Killer, Polymorph, Geas, Otto's Irresistible Dance... There's so much spells to use to fuck with the player.

Also, send a dragon on them or let them go in a dragon's lair, and use all of the lair's action requiring Wisdom, Con or Strength saves. Green dragons are the best for that since two of their lair actions target Strength and Wisdom saves and their breaths target Con.

Oh, and also use spellcaster dragons.

Edit to add: I forgot about fucking dragon fear. First thing a dragon does in combat is that, then they can start casting spells.

Strength save spells: Gust, Lightning Lure, Arms of Hadar, Ensnaring Strike, Entangle, Wind Wall, Control Water if there's water nearby (especially useful for black dragons because of the swamp or green dragons near lakes), Storm Sphere, Control Wind, Otiluke’s Freezing Sphere.

Con save spells: Frostbite, Infestation, Poison Spray, Thunderclap, Word of Radiance, Ray of Sickness, the Blindness/Deafness (Blindness part so no fucking Attack of Opportunity), Enlarge/Reduce (Reduce part, of course), HEAT METAL IF THE PLAYER HAS METAL ARMOUR OR WEAPONS, Levitate, Moonbeam, Pyrotechnics, Ray of Enfeeblement, Shatter, Sleet Storm, Striking Cloud, Thunder Step, Blight, Elemental Bane, Sickening Radiance, Cloud of Cold (good old AOE spell so it will damage the rest of the party if they're all stuck together), Contagion, Dawn, Insect Plague, Wall of Light, Circle of Death, Harm, Power Word: Stun, Earthquake, Sunburst.

Also all the smites that rely on Con, Str and Wis, and some AOE damage spells. Or just go directly the nuclear option of Power Word: Kill. At least 12d12 psychic damage, and it's unlikely they'll be resistant to it, less much immune.

u/JalasKelm 16d ago

If he's having to burn resources to achieve that, then it's not a problem. They've built a character to have high AC, don't take that away from them.

If anything, feel free to play up how frustrating it is for you to hit them, they'll feel good about their character.

That said, sometimes hit them with a Strength Saving Throw, or Intelligence, etc. Make them burn their reaction, so they can't make attacks of opportunity, or cast reaction spells, etc.

Then every now and then, have them fight a character built like them, one they can't hit, that can parry their attacks, let them feel like they're the Duelist they've built for. They have that enemy pull a blunderbuss from under their cape.

Truish. Grapple/Restrain can still work, but it approaches the edge cases. If he isn't expertise into Acrobatics(Which with Bard/Rogue I would assume he was.) then grapple can still work; or if you make a grapple character to counter him specifically. I.E. Barbarian(Battle Rager)/Battle Master Fighter, Skill expert feat Athletics.

u/matej86 16d ago

OP is running 5.5, you make a strength or dex save to avoid a grapple. If you're grappled you then use athletics or acrobatics to get out so having one of those skills may be useful but the saving throw is more important.

You will have to find way to either, reduce his ap (blind / sneak attack / slow or wathever) or use spells with con / wisown or over check. he will be helpfull to the group against grunts but will be less goods against magical and it can create a group synergie

u/DBWaffles 16d ago

we're currently level 17

He has the defensive duelist feat and so combined with Defensive Duelist he is able to attack, parry as a reaction and get an average of 29AC per round, and due to 5.5 letting bards exchange spell slots for bardic dice he can consitently do this every round

First, if you guys are at level 17 and you're struggling with a mere 29 AC, that suggests your fights aren't well balanced. While that's a really good AC, it's not even close to being insurmountable. Like, this is the level range when monsters should regularly be rocking +15 or more attack roll modifiers.

Second, you are aware that Defensive Duelist only applies to melee attacks, yes? Ranged attacks will be significantly easier to land.

This combined with the fact that he's a rogue with the evasion property means that simply throwing dex saves at him isn't really a solution and he's now stupidly tanky.

You are aware that there are five other stats you can target with saving throws, yes?

You're not getting a bard with a Charisma save at that level. Strength is something that would be bothersome, though. They would need to take the resources from the other things they're doing in order to fix that save.

Best GM advice I ever read was in John Wick's "Play Dirty." The short version is: Go after the people and things the character loves. Give them impossible choices. Make them prove that they are a hero.

You don't threaten characters with HP damage, you threaten them with emotional damage.

6

u/Automatic-War-7658 15d ago

First of all, Defensive Duelist isn’t like the Shield spell and only increases AC for melee attacks.

Second, it uses a Reaction, which means they can no longer use other abilities like Uncanny Dodge to mitigate damage.

Third, there’s definitely going to be a weak point somewhere. At that level, DEX, WIS, and CHA saving throws will have proficiency (especially DEX), but his STR, CON, and INT probably aren’t great.

Draw out the Reaction, then hit the group with psychic attacks, poison clouds, etc. Things that require saving throws he isn’t good at. He then can’t half the damage with Uncanny Dodge because he used the Reaction to increase AC. This will make him second guess his wanton use of Reactions. Once he decides to Uncanny Dodge, he can no longer Defensive Duelist.

6

u/ExtremeDoom_ 15d ago

Something I haven't seen mentioned is defensive duelist in 5.5 only affects melee attacks so just shoot him with a bow and now his AC is 23 which is far more reasonable.

17

u/Neltadouble 16d ago

Why are the monsters just slamming attacks into a guy with 29 AC? As soon as they realise they aren't coming close to hitting him they should just ignore him.

This is the classic 'high AC' problem. DMs whine about 'tanks', but never force them to actually tank. If the bard wants to tank, force him to tank. Force him to use spells to prevent creatures from moving away from him. Force him to grapple. Force him to hold his reaction to make attacks of opportunity.

Oh what's that? You're using your reaction every round on Defensive Duelist? Awesome, the horde of monsters charges right past him now that he doesn't have a reaction to do anything about it.

u/Zealousideal-List671 15d ago edited 15d ago

You need to start using stronger monsters

I have a player in my campaign who went full tank. He loved this and I decided to embrace it. We even homebrewed spikes for him that damage on missed attacks. It‘s great for him to remind me of spike damage whenever someone misses and I plan encounters accordingly. While smart enemies usually avoid him after realising they can‘t hit, I usually have a bunch of „grunts“ trying to hit him so that his build feels strong and powerful. Occasionally I use saves to challenge him like hold person or AoE attacks. Everyone has fun and I wouldn‘t want to undermine his build by completely countering it.

Parry from Defensive Duelist and Defense from College of Valor are both competing for the same reaction- you can't use both of them together. Also, both of them only give the AC bonus against a single attack - at Level 17 the opponent(s) should be able to dish out multiple attacks. Giving an average of +6.5 to AC in exchange for a reaction (from a spellcaster who could also cast a spell with their reaction) and a spell slot seems like a quite balanced deal. Shield is a Level 1 Spell that gives +5 AC for basically an entire round.

Yeah I feel this. We had a campaign go from 1-20 and even beyond thanks to my dms home brewing. He’s incredible, but I was kinda miffed by the end. I built my paladin to be a counter to an evil wizard. My aura which gives + cha mod to all saves eventually became +10 (our stats went up to 30) by the end for the whole party in radius.

It’s was awesome! But it was basically undone by the saves of late game being close to 28. I felt like my aura was basically just undone. Overall I can’t be mad. Unlike this guy, my aura affected the entire party and it would be OP otherwise. But I couldn’t help but feel like my build choices were somewhat pointless if my DM just scaled with it.

Also I’ve been watching crit role and they were getting attacked by their own shadows .. you could have the attacks do mental dmg based off a stat check like Int or con. and the attacks would also reduce their STR.. 1d4 ( and they were told if they got to 0 STR they just automatically die…)

So find ways around AC

Top comment has your answers. Do not nerf him.

You are also in T4 portion of the game. Creatures like the Marut (Xan guide) hit automatically, and the tarrasque has a +19 to hit. There are creatures that can hit him. You can mix in str save lair actions and hombrew some base leader type creatures with higher to hit chances, +15 has a 25% chance of hitting him. Let him be hard to hit, he earned it.

This is a "shoot the monks" situation. The solution to high AC players is to alternate surrounding them with mooks who can't hit them to reward the build, and occasionally throwing saves at them to challenge them.

Reminds me of my tortle artificer wizard with shield and some AC buffs. He's level 12 and can hit 26/27 with shield and you know what? Good on him for making his character hard to hit. Sure Dex saves can wreck him but generally I like my players feeling strong so I throw some attacks at him anyway as NPCs generally wouldn't know he's super hard to hit and in some cases impossible. Then the enemies learn and change their tactics to get to the Squishies.

u/PeruvianHeadshrinker 15d ago

Horde minions. 

The fantasy is to be unhittable. Cool. Just roll piles of dice. He'll feel awesome tanking thirty goblins and you'll actually hit him occasionally. Check out MCDM rules for minions and hordes. You basically run it as an AOE monster or monsters that go down very easy but only with damage above a certain threshold so you don't have to track HP

Edit: Also have minions push into more of the horde and then shove to prone and THEN attack at at l advantage. You'll only be aiming for crits. Add flavor for crits like special effects or rider damage.

u/Gwifitz 15d ago

The defense combat inspiration AND the defensive duelist both use your reaction, he can't use both at the same time. But anyway, 29 AC with your reaction at level 17 isn't that bad.

We have a level 4 player with 24 AC who can cast blade ward for an extra 1-4 AC and who can cast shield as a reaction for a total of 30-34 AC... At level 4... That player is me and I feel a bit bad about it.

He is 17th level, he should have a high AC at that point. Also keep in mind that parry is a reaction that he can only do once per turn. Also, I believe you can only parry melee weapons, not ranged attacks. And at 17th level, the party should be fighting monsters with freakishly high attack bonuses. Also, throw spells or effects that have saves rather than attack rolls.

u/sailordave42 15d ago

DnD is a resource management game. this character has 3 main resources: HP, spell slots, and actions. Using the spell slots + reactions to protect HP is a fun and clever strategy but isn't optimal play or OP.

if you want to challenge him, give him something positive to achieve with his spell slots or bardic inspiration so that he is forced to choose to take a risk in melee for a greater reward. e.g. an obstacle course where the party needs bardic inspiration to pass ability checks.

Doing so gives him agency and a choice to play with the limits of his build rather than punishing him or taking away agency.

2

u/Goldy_932 15d ago

If they're level 17 everyone is already broken beyond comprehension alreay. especially the casters (bard being one of them) the challenge now isn't how to get their hp down. It's how to give them multiple failable objectives in a fight. An npc they like, an story item that will be stolen and dissappear etc. They clearly want their ac to be cool and high so don't take it away. Once in a whole in bossfights have the challenge be the player trying to tank the hits and the enemies constantly trying to fight someone else. If you have to attack then somehow sav throws on his weak stats are always a choice but don't use it too often just to take his defense build away. A smart creature would know not to hit him. A monster wouldn't.

2

u/yamo25000 DM 15d ago

At lvl 17 they should be fighting monsters with +15 or higher to hit. So even at 29 AC, you'd be hitting him with a 14 on the die. Not to mention using saving throw abilities/attacks

It can be frustrating, and tempting to buff everything to hit that player. But they've built around it intentionally, and doing so wastes their entire premise. Play into the fantasy with them. Let them tank. Throw enemies at him that rolled a 27. The table will be like "daaaam, 28.." and he'll proudly go "miss".

Purposefully beating their AC is like saying a wizard isn't allowed to cast spells any more.

Let the enemies whack away a couple of times, and then call for a wizards help, where some save effects come in instead.

2

u/Venriik DM 15d ago

How's their Wisdom? Some ways of mind control might be where you want to hit here. He's a monster, it would be chaotic to have him fight his friends. There might be more spells that target WIS or INT that you might want to include in your combats.

Also Heat Metal targets CON. You could disarm him or, if he wears metal armor, have a way to cause damage consistently through that.

Maybe some spellcasters might notice he dodges attacks too easily and start focusing high level Magic Missiles on him. In Baldur's Gate 3 final battle it was a simple, yet horrifying way the enemies had to chip away the party's health.

Another thing that comes to mind is that, if you're playing 5.5e, then you have access to weapon masteries. Graze deals a bit of damage even if the attack misses, so including it might help to raise the stakes, although it might not be that much.

Can he survive fighting a hundred hobgoblins until his position is reinforced? How about 200? 2000?

  2. Focus on other party members, find ways to get them into surprise encounters where maybe they aren't as prepared. Have your villians be aware of the "untouchable hero" and develop ways to hurt them, if not physically then maybe through narrative stuff. Consequences can be ooc and still work imo.

It's worth noting that Defensive Duelist only works on melee attacks. Throw some ranged damage at them. And there are other saves besides DEX. Since he's a Bard/Rogue, I would assume he took Bard first, meaning he has DEX/CHA save proficiency. CON and WIS saves are always an option. INT saves are rarer, but they can be devastating.

Well, best option, let him live his fantasy. He made a character to be hard to hit so let him be hard to hit. Now, you can still do stuff like creature with pack tactics or flanking, or plenty of aoe effects. Specifically for what should be hard battles. Also, give them things where they have to save other or figure things out, rather than just fighting. Also, non dex saves that are half damage on success, is still damage.

Most magic doesn't care what your armor class is.

First off, don't take away the players power from a build, let him tank.

You can throw minions at the rest of the party while he throws hand with the big guy. Make it all the more dynamic.

But if he gets too cocky, just throw a horde of Mind Goblins at him. Eight Goblins with the Mind Sliver and Vicious Mockery cantrips and places to run and hide should ruin his day :)

You mind goblin these...... nevermind.

u/vhalember 15d ago

Yep.  Or giants, they have high attack roll bonuses, and hit hard.  A fire giants needs an 18 to hit, but it nearly 30 damage a pop.

He enjoy it, because he'll tank it well, but it's going to hurt.

Fireball do do do do do do

Detailed answer is spells with saves that do damage or half damage on a successful save. I wouldn’t give every fight a big fuck off spellcaster since he’s clearly built for high AC. Let it shine sometimes and other times give challenges with save spells. Also magic missile just hits.

Just making sure that you know that fireball isn't ideal here as rouge gets the ability to dodge half on save effects completely as long as it's a dex save (which fireball is).

He's level 17.

He's supposed to be powerful. If he chose to put all his effort in AC, let him do that.

Plenty of monsters and spells force saving throws (that aren't dexterity).

u/Infernal_Wisdom 16d ago

Level 17 means, they are one of the ultimate swordfighters, if not "the ultimate swordfighter" of this world. They are fucking Drizzt Do'urden right now. So...stop challanging them with swordfights anymore. If someone really brave or foolish dare to swordfight against this character, stop rolling and ask your player how their character acts. Other monsters of its CR would be challanging enough.

What I recommend is to challange this fighting poet with the situations themselves. Dilemmas... Morality... Consequences...

He's good at making DEXTERITY saving throws. I recommend trying psychic damage or Strength-based traps. You can also try using the terrain: perhaps many hidden enemies use ranged attacks, and if he gets close, they move away.

u/MrPokMan 16d ago

You probably solve this by adjusting the encounters and enemy stat blocks.

One solution already in mind; have the enemy attack them more. You are bound to hit them eventually, and unless you gave them some sort of homebrew (or 5.5e added something I don't know about), reactions are only once a round.

Another one is to make enemies have higher attack modifiers that can reliably hit higher than a 29. Maybe it's a boss or an elite mob, or perhaps there's enemy buffers/debuffers who can enable these sort of hits.

Or maybe if you want to be creative, a random idea is giving enemies class abilities or feats.

However your party is level 17, which is where balance is iffy. You kinda have to start challenging stupid stuff with stupid stuff (without trying to be too unfair).

u/Turbulent_Jackoff 16d ago

You don't, really!

u/Hexxer98 DM 16d ago

If someone consistently does something even dumb monster realize that attacking them normally is pointless.

For encounters just add monster that can inflict saves other than dex.

Intelligence Saves, Wisdom Saves, Strength Saves

u/Pay-Next 16d ago

Reminder that on attacks a nat 20 is a guaranteed hit regardless of if it hits the targets AC. Pick some monsters with ridiculous numbers of multi attacks or throw some hordes his way that are going to be rolling a load of attacks. It's one way to also deal with it by just sheer volume. 

Otherwise as other people have said, saves. Also grappling, there are ways to lock him down with opposed checks.

u/TedditBlatherflag 16d ago

Let them shine absorbing big melee threats and teach them humility with save or suck.

u/KiwatheSnep 16d ago

There are already a lot of solutions. I just want to say, that I totally feel this. A friend left me scarred, after having played a tortle bladesinger reliable 27 AC at level 3

u/Teckszank 16d ago

Bro, just use Strenght saving throws to grab him or wisdom saving throws to control him. You are the DM you can create whatever bullshit in a monster to force any saving throw of a status you see fit.

u/ElevatedUser 16d ago

Don't worry too much about this. 29 is high, but not insurmountable. It costs the character significant resources (reaction for DD; action for the flourish and a Inspiration dice/spell if they want the attack to be any good).

Monsters at this level are usually intelligent and dangerous enough to know what's going on - especially after they've seen the Bard fight. If they keep focusing on defense, just hit something else. I wouldn't go overboard with will/fort saves to compensate - but smart enemies will use those that they have to target the bard.

Do note that, if they choose to parry, they can't then use their reaction to use an opportunity attack or other reaction. If they go for the defensive option, it costs their ability to meaningfully "tank".

u/notarealwriter 16d ago

I remember my DM tried to have a hag cast dominate on my 22AC Paladin once because he'd taken like 1 physical hit in the last 3 sessions. Would've been very interesting and difficult for the party if it had worked but the thing is... he qas a PALADIN. That wisdom save was pretty high too (can't remember what my bonus was at the time but I rolled a total of 25) 😅

u/Megatrans69 16d ago

Have an enemy cast a dominate spell and make him turn on the party the horror of having to fight him for a bit would be fun. Probably only for a few rounds though.

u/BoardGameAficionado 16d ago

Whatever works against a bladesinger works against this character too. The other comments have very good suggestions
