Armour of Storms

The power of storms above is called to protect you, surrounding you and your gear in an armour of thunder and lightning. After being hit with a melee attack/spell, you can use your reaction to deal 1d6 lightning damage to your attacker.  Additionally, when you are hit with an attack made by a weapon, the attacker must make a STR/DEX save against your spell save DC. On a failed save, the attack misses. Once the spell ends, you take 3d6 lightning damage as the storm's energy returns to the sky, shocking you.
