Crown of Radiance

A halo of brilliant light appears over your head, shedding bright light in a 20-foot radius and dim light for an additional 20 feet. Upon activation, all creatures within 5 feet of you must roll a Constitution saving throw. Creatures with sunlight sensitivity and any aberrations, fey, fiends, or undead have disadvantage on this save. On a failed save, a creature is blinded until the end of your next turn. In addition, any aberration, fey, fiend, or undead that comes within 5 feet of you or starts its turn there must succeed on a Wisdom saving throw against your spell save DC or take 2d4 radiant damage.
