You surround yourself in cosmic flames and become an avatar of an infernal angel. You grow wings of flame and glow with the intensity of a thousand suns. You gain full immunity to fire and radiant damage and resistance to sharp and force damage. Any spell attacks made deal an extra 3 damage dice. This transformation lasts for 3 turns and when it ends you dispel all the energy in a 5 tile radius as fire damage. All creatures in the affected area, excluding yourself, take 3d12 fire damage and you half your remaining health.
