From the publisher's web site: This month, Unearthed Arcana returns to the mystic character class and the rules for psionics. Based on the playtest feedback you sent us, there are a number of changes you can expect: The class now goes to 10th level. The core concepts had enough support that we feel confident moving forward with them. Psionics is more flexible. You have a psychic focus, which allows you to pick one discipline and gain a constant, special benefit from it. Otherwise, you can expend points to use any discipline you know. Psionics now includes psionic talents, the equivalent of a spellcaster’s cantrips. Psionic disciplines are now available to all mystics, regardless of mystic order. However, your order grants you a benefit for using its associated disciplines.
