But while I'm on the topic of illithid wisdom checks, the DC to break SH out of her pod in the build I played was 2. Implying to me that we are going to get harder illithid checks as the game progresses. It was always a bit weird in EA that we were rolling checks with 0 DC.
That likely(*) means they are keeping Natural ones as automatic failures for skill checks and simply removing the incongruity of a 1 failing a difficulty 0 check.
(*)baseless speculation that could very well be wrong
