Arcing Cloak

This protective spell shocks anyone who tries to hurt you. You have small lightning strikes around you resembling a Cloak. You gain 1d8 + your intelligence modifier as temporary hit points for the duration. If you deal damage through magical means while you have these hit points, you may remove 4 temporary hit points and add 1d8 lightning damage to that.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, both the temporary hit points and the lightning damage increase by 1d4 for each slot level above 2nd.
