Celestial Aura

You focus on all the joy inside yourself. The caster emits a bright yellow aura that heals any creature they wish to heal in a 20 foot radius. Upon being affected by this spell, a creature regains 10d12 hit points and has all negative effects removed. A target of this spell also gains advantage on their next attack roll, ability check,  and saving throw. If this spell is cast twice by the same user in a 1 hour time span, the caster suffers 3d6 psychic damage and must rest on their next turn before being able to do anything again. This spell can also be cast as a bonus action, but only heals 3d12 hit points, does not remove any negative effects, and does not give advantage to any rolls.
