You may channel your ki power into healing and banishing weariness from your body.
Prerequisite: Ki power.
Benefit: You can spend one daily use of ki power to heal yourself a number of hit points equal to half your ninja level (minimum 1) multiplied by your Wisdom bonus. Alternatively, you may instead spend one daily use to remove the fatigue condition or reduce the exhausted condition to fatigued.
