Potion of Lightning Shielding

Rare Potion

Liquid Shield. The bright yellow liquid in this bottle flashes with a bright white light occasionally. Drinking the potion sends a little shock through the body and numbs the mouth a bit for a few seconds.
When you drink this potion, you gain resistance to Lightning damage. Sparks and thin bolts of lightning arc around your body, shedding bright light in a 10ft. radius and dim light for an additional 10ft. Additionally whenever a creature within 5ft. of you hits you with a melee attack, the shield erupts with bolts of lightning, dealing 2d8 Lightning damage to the attacker. These effects last for 10 minutes.
