Divine Light

You call upon the divine powers of the gods to aid your allies and weaken your foes. For one minute, a divine light shines from you, casting bright light in a 30 ft radius. The light dissipates magical darkness up to 3rd level. 

Heal. Any ally starting its turn within the light regains 1d6 hit points.

Harm. Any non-ally starting its turn within the light must make a constitution saving throw. Non-undead creatures take 1d6 radiant damage on a failed save, or half as much on a successful save. Undead creatures take 2d6 radiant damage on a failed save, or half as much on a successful save.
