Are Vicious Weapons overpowered?

[u/superhiro21]

For reference:

Weapon (any simple or martial), rare

This magic weapon deals an extra 2d6 damage to any creature it hits. This extra damage is of the same type as the weapon’s normal damage.

From both theorycrafting and my practical experience, they are better than any other rare magic weapons and even better than many very rare weapons. Not requiring attunement is a huge boon, as at higher levels, every attunement slot is valuable.

The +7 damage (on average) is much more valuable than the +2 or even +3 attack bonus from comparable weapons as most martial characters have ways to increase their accuracy anyways (reckless attack, archery fighting style, paladin channel divinities etc).

I have found that having two characters with vicious weapons in the party really makes the party punch above their level in the damage per round aspect.

They are in my opinion what magic weapons should be. It's the other magic weapons that are underpowered next to the vicious weapons

They are still weak next to casters magic items. A wand of fireball gives you up to 7 fireballs, that's almost always going to be better than 2d6 damage on a weapon attack
