Psionic Study

Choose one psionic discipline. You can manifest powers from this discipline, though you do not gain the ability to use the disciplines psychic focus unless you are a psion.

• Psionic Ability. Your psionic ability can be constitution, intelligence, wisdom or charisma.
• Psi Points. Your psi point total is equal to 2 times your proficiency bonus. You recover all expended psi points when you finish a long rest.
• Psi Limit. Your psi limit is 1 less than that of a psion of the same level (minimum 1).
  Special: Psions who select this feat gain the selected discipline and add 6 more psi points in addition to those granted by their class. This discipline does not count against the number of disciplines or orders you know.
