Cloak of Darkness

A cloak of darkness envelopes you until the spell ends, causing you to become heavily obscured to others unless they can see through magical darkness. At the edge of the cloak, dark shadows seem to reach out and dim any lights within 10 feet of you into darkness, and bright light in the same area to dim.

Until the spell ends, you have resistance to radiant damage. When you are hit with an attack by a creature within 10 feet of you, dark forms reach out and attack that creature, dealing 2d8 necrotic damage.
