Electric Armaments

You touch a metal weapon, metal shield, or suit of metal armor and imbue it with elemental lightning for the duration.

If the imbued object is a weapon, it deals an extra 1d6 lightning damage on a hit.

If the imbued object is a shield or a suit of armor, whenever the wearer is hit by a melee attack, the attacker takes 1d6 lightning damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
