Why not? I mean, all the tadpole powers manifest differently. Fighter has the ability to pull a creature to them. Warlock teleports to an ally. Rogue creates darkness cloud. Wizard reflects. Cleric comes back to life. All different based on class.
These aren't the illithids you're used to. That's the whole point. Right?
I'm talking about the [Illithid, Wisdom] rolls in dialogue.
Not all this junk you're bringing up that doesn't need a roll. I accept that psionics can do a multitude of different things. That has zero to do with what stat's being rolled in the dialogue choices.
I feel like I'm pulling teeth trying to get across the most basic concept here. Illithids use the Int ability for their powers. The dialogue roll claims it's an illithid power, but uses a wisdom roll. Maybe that roll should be Int instead.
