Strength of Mind

Even the simplest psionic technique requires a deep understanding of how psionic energy can augment mind and body. This understanding allows you to alter your defenses to better deal with threats.

Starting at 4th level, you can replace your proficiency in Wisdom saving throws whenever you finish a short or long rest. To do so, choose Strength, Dexterity, Constitution, or Charisma. You gain proficiency in saves using that ability, instead of Wisdom. This change lasts until you finish your next short or long rest.
