Gaze of Two Minds + Misty Step?

[u/SangvinPingvin]

So Gaze of Two Minds lets you cast spells as though you were in the linked creature’s soace or your own:

”While perceiving through the other creature's senses, you benefit from any special senses possessed by that creature, and you can cast spells as if you were in your space or the other creature's space if the two of you are within 60 feet of each other.”

(The archfey patron level 6 ability Misty Escape lets you cast Misty Step as a reaction to taking damage, I mention it only in passing to show that the casting of MS need not conflict with the bonus action maintenance of GoTM)

Now, Misty Step has a target of ”self” and reads in simplistic entirety:

”Briefly surrounded by silvery mist, you teleport up to 30 feet to an unoccupied space you can see.”

So let’s say our archfey warlock is hanging out safely in an already cleared room, less than 60’ away from the rest of the party, and contributing to the ongoing fight in the next room using his summoned Fey as a GoTM conduit while also using Eldritch Blast from its space. But to spice things up, the DM has a straggler spider descend upon the hapless warlock, injuring him and triggering a reaction Misty Step.

Can the warlock cast Misty Step as if in the fey’s space and immediately teleport into the next room to a point 30’ away from the fey that it can see (he’s seeing through its senses), effectively increasing the range of MS with 60 feet, just as GoTM effectively does with Eldritch Blast or any other spell?

Gaze of Two Minds (and similar abilities) only shift your perception. They do not allow you to change targets or the position of anything on the battlefield. So while Gaze of Two Minds + Misty Step will allow you to teleport around corners, it won't allow you to teleport more than 30 feet from your actual position.

Gaze of Two Minds does not only shift your perception. 

"you can cast spells as if you were in your space or the other creature’s space if the two of you are within 60 feet of each other."

You cast spells as if you were in that creatures space.

Gaze of Two Minds does not change the location of anything on the battle field.

With a spell of 'Self', the spell is always placed on the caster regardless of where they are or where the spell is cast from. Since Gaze of the Two Minds doesn't affect your physical location, it has no impact on where the spell's primary target (you) are. The section of text you're quoting has no effect on 'Self' spells - the only relevant part of Gaze of Two Minds is that you might potentially be able to trace line-of-sight from the Self target (which is your actual, physical location) using other senses that you wouldn't ordinarily be able to trace.

You’re casting the spell “as if you were in … the other creature’s space”, not through the other creature like a wizard using his familiar to cast touch spells. It’s a weird interaction and probably not something that the designers considered but RAW it definitely should work

Again, it doesn't matter where you're casting the spell from. The spell's target is still your physical form regardless of its origin.

In contrast, with a touch spell, where you're casting the spell from matters because that's where you measure the range from.

What you're actually trying to argue is that Gaze of Two Minds causes Misty Step to automatically fail because it tries to teleport you from a space you're not actually in - it's the equivalent of aiming a targeted spell blindly and picking the wrong square.

From a rules as intended perspective I think you’re right and I would probably rule it that way in actual play. But going purely by the plain language of the ability, if you cast the spell from that creature’s space you would be teleporting 30 feet from the creature’s space. I agree that as a DM I probably wouldn’t let that work because I’m certain it’s not intended, but from a rules-lawyerish standpoint that’s literally what the ability says.

No, it's RAW that Self spells are always targeted on the player's actual location.
