Channel Negative Energy — Heal Undead

Channeling negative energy causes a burst that heals all undead creatures in a 30-foot radius centered on the cleric. The amount of damage healed is equal to 1d6 points of damage plus 1d6 points of damage for every two cleric levels beyond 1st (2d6 at 3rd, 3d6 at 5th, and so on).
