Eclipse

A silvery beam of pale light shines down in a 20-foot-radius, 40-foot-high cylinder centered on a point within range. Until the spell ends, dim light fills the cylinder.

At the start of your turn, choose which creatures inside the area of effect are friendly and which creatures are enemies.

A friendly creature is engulfed by a soothing pale moonlight that heals them for 3d10 + your spellcasting ability modifier.

An enemy creature is engulfed in ghostly flames that cause searing pain, and it must make a Constitution saving throw. It takes 3d10 + your spellcasting ability modifier radiant damage on a failed save, or half as much damage on a successful one.
