I'm more concerned with the Illithid dialog checks that you can pass or fail.
Im quite honestly not sure there even is any ...
Illithid choices i remember are easy win no matter what. O_o
I’ve rolled 1 and failed illithid checks before! And I guess if you played a character with a wisdom penalty you might get more fails too. Though I do wonder at the point of making this a roll at all when it’s so unlikely to fail. Perhaps that might become clearer later.
(I confess I didn’t notice whether failed checks counted as a use of the power for True Soul progression or reuse of power that day. If not, then perhaps Larian are thinking of making the rolls harder in the full game.)
