Spark Shield

4th-level evocation

Casting Time: 1 action

Range: Touch

Components: V, S

Duration: 10 minutes

Electricity sparks to life over the form of a creature you touch for the duration. You can end the spell early by using an action to dismiss it.

The electricity provides you with an electrified shield that also provides you resistance to lightning damage.

In addition, whenever a creature within 5 feet of you hits you with a melee attack, the shield sparks with electricity. The attacker takes 2d8 lightning damage and must make a Constitution saving throw. If they fail, they are stunned until the start of their next turn. Any creature that hits you with a melee weapon attack that is using a metal weapon takes 4d8 lightning damage instead.
