Twilight

You call upon the moon to aid you, and a soft, silvery light shines down on a an area you choose within range. Until the spell ends, a 30-foot-radius.40-foot-high cylinder of dim light glimmers there. This light counts as moonlight.

Creatures you choose within the cylinder regain hit points equal to half your Cleric level when they start their turn within the cylinder, and are immune to being charmed and frightened while they remain within the cylinder.
