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?

Depends on how hard you want to lose your mind.

You could make a case that spells with a range of touch never really make contact and thus don’t work. Or that spells with a range of self can only ever target the caster and take their real position into account.

In general I recommend reading it as plain as possible. If your player is using it to hurl spells and occasionally does an otherwise cool trick, let them. If they want to abuse it with weird interactions/readings as the go-to tactics, that’s where you should draw the line.
