5th-level evocation
Secret Spell: Faithful of Hurrian
Casting Time: 1 action
Range: Self
Components: V, S, M (a small sliver of iron)
Duration: 10 minutes

Crackling tendrils of lightning wreathe your body for the duration, shedding bright light in a 10-foot radius and dim light for an additional 10 feet. The lightning gives you resistance to lightning and thunder damage; if you already have resistance you gain immunity instead.

In addition, whenever a creature within 5 feet of you hits you with a melee attack, the shield erupts with lightning and your attacker takes 2d8 lightning damage.

You can end the spell early by using an action to dismiss it.
