So a fighter with an Intelligence of 8 gets hit with a maze. Am I correct in assuming that he can't escape for 10 minutes because he could never get a 20 on an ability Intelligence check?
I'm just popping in to say that you (and Pizza Lord) are correct.
Goes to show you that you should never dump your intelligence, or if you do, at least get something to boost it up.
Reminds me of the time the party got hit by a symbol of insanity, and the bloodrager who dumped int failed his willsave, and was accidentally targeted by another confused party member, and to keep them from killing the whole party, the witch put the bloodrager in a maze. Problem was, he was still insane, so the entire 10 minutes was enough time for him to kill himself with d8+Str, so only his mauled face and corpse came back when the maze ran out.
