Channel Positive Energy — Damage Undead

Channeling positive energy causes a burst that damages all undead creatures in a 30-foot radius centered on the hospitaler. The amount of damage inflicted is equal to 1d6 points of damage at 4th level plus 1d6 points of damage for every two hospitaler levels beyond 4th (2d6 at 6th, 3d6 at 8th, and so on). Creatures that take damage from channeled energy receive a Will save to halve the damage. The DC of this save is equal to 10 + 1/2 the hospitaler's level + the hospitaler's Charisma modifier.
