Aura of Purification

Healing flames radiate from you in an aura with a 30-foot radius. Until the spell ends, the aura moves with you, centered on you. You can use a bonus action to cause one creature in the aura (including you) to regain 1d4 hit points, or a target must succeed on a Dexterity saving throw or take 1d4 fire damage. The aura ignites any flammable objects in the area that aren't being worn or carried. The aura provides bright light within the 30-foot radius and dim light for an additional 10 feet.
