Said another way, you will always fail the check. 😭
Exactly my point ...
Why it even exist? O_o
Its like:
Here you can open this dialogue, if you spend this extra rare resource >> you can proceed in dialogue you opened with extra rare resource, if you spend extra rare resource you had to spend to even get here.
What? o_O
Seems like oversight to me, but its present for almost 2y by now.

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
