Cleansing Rain

Mystical rain falls in a 20ft radius at a point you can see within range, freeing your allies of harmful effects. Any ally that enters the radius for the first time on a turn or begins their turn there regains hit points equal to 2d6 + your Wisdom modifier. The first time an ally regains hit points this way they also have one level of exhaustion removed. If the ally is poisoned, frightened, or charmed these effects are removed as well. The first time an undead creature moves into the radius or begins its turn there it must make a Wisdom saving throw or suffer 2d6 + your Wisdom modifier as force damage.
At the start of your turn, you may make a Wisdom check to move the circle without expending a spell slot.
