A soft, white radiance spreads out from a point just above your head, creating bright light in a 30-foot radius around your present location. If you move from your present location, the area of light remains fixed. A creature in the area other than a fiend or an undead regains 1 hit point at the start of each of its turns while within the bright light. Each fiend or undead in the area takes 2d4 radiant damage at the start of each of its turns.
