blessed light

Creates a heavenly light that heals each non-hostile creature by 1 hit point per action the spell is active. Each hostile creature takes 1d4 damage per action started. As soon as the light appears, all hostile creatures within range of the spell must make a Constitution saving throw (1d20). A roll of 15 or higher is required; otherwise, enemy creatures take 1d4 less damage for 1 action, repeated per action within the spell's radius.
At higher levels: When you cast this spell using a 9th-level spell slot, you summon a celestial being that doubles the healing.
