Enegry pulse armor

Your bronze scales pulse with electrical energy. A soft humming sound is coming from this energy.  You have disadvantage on all stealth checks. 

Whenever a creature attacks you with a melee attack an arc of electricity jumps out and hits the creature for 2d6 electrical damage and they are stunned for one round on a failed dexterity  save. On successful  on it is half damage and the creature is not stunned. If the creature is resistant to electrical  damage it get auto save, if it is immune nothing happens.
