1.2 after reviewing the other monk subclasses more closely I decided to have damage of psionic abilities be based off of your martial arts die+ intelligence . In my haste to upload the first draft I forgot to let you use your intelligence modifier in place of wisdom modifier for unarmored defense. I also have decided to limit the amount of Psionic enhancements you can learn each level to bring it more in line with similar subclasses. A Psionic Die is equal to 1 ki point when using the enhancements. 1.1 At third level you develop Psionic abilities, these are represented by your Psionic dice, you are given an amount equal to two times your proficiency bonus and these come back on a long rest, starts at a D6, at 5th level it increases to D8, 11th a D10, and 17th a D12, the extra damage is force damage. Your Ki saving throw is 8 + intelligence modifier + proficiency bonus.

Psionic Awakening

At third level you develop Psionic abilities, these psionic abilities are accessed through your connection with ki. Upon developing these abilities you can choose how they manifest choosing from an expanding list at 3rd level you can one from a list of three ways to augment your monk abilities.
