new creature Star Spawn Hulk, shouldn’t the RAW of Psychic Mirror be “each creature other than a star spawn hulk”??? Or the infinite pinball damage is a thing that your considered? It works as intended. None of the hulks would take the psychic damage.

But a third creature, like a player, or a Tarrasque, would take infinite psychic damage because of the pinball looping that the feature creates, right? (if there is two hulks next to each other) Game features with the same name don't stack, so nearby creatures should only take the damage once. Multiple hulks could increase the effective area though.

That's correct, @armando_doval.
