@JeremyECrawford Why no disciplines for the Soul Knife? They seem to have gotten the short stick in the Mystic.

Every mystic has access to every discipline. Read the Psionics class feature. #DnD https://t.co/rmPJfRVY1e

@dmheartstrings Disciplines serve the whole class. None of them serve the class features of only one subclass.
