Personal Boon at Sohei 3: the Sohei gains damage reduction 1, shrugging off 1 HP of damage from each attack that breaches her defenses. This DR increases to 3 at Sohei 4 and caps at DR 5 at Sohei 5. The Sohei class doesn't go beyond level 5.

Party Boon at Sohei 1: Once daily, a Sohei can expand her ki aura for a single round to encompass allies within a twenty-feet radius of the Sohei's position. For that single round, the sohei and affected allies enjoy Damage Reduction equal to the character's Sohei levels, plus the Sohei's Wisdom modifier. The Sohei can exercise this ability even at Sohei 1 and 2, before the Sohei gains ongoing DR.
