Dissonance of the Raven Queen

You draw power from the Raven Queen’s realm, Shadow-like mirages cover your body until the spell ends, causing you to become heavily obscured to others. Any exposed non-magical flames within 10 feet of you are extinguished. Until the spell ends, you have resistance to radiant damage. In addition, whenever a creature within 5 feet of you hits you with an attack, the shadows lash out at that creature, dealing it 2d6 psychic damage.
