Electrickery

A sparking current of electrical energy instantly swirls around you, bolstering you against future attacks. The attacking target must make a dexterity saving throw. On a failure, it takes 6d4 lightning damage and remains incapacitated until the end of its next turn after this attack is made. On a success, it takes half the damage and is not incapacitated. This damage occurs before the attack is made.

Immediately after the attack is made, you can move up to half your movement speed without provoking attacks of opportunity. All attacks made against you are at disadvantage until the end of your next turn, and successful attacks made against you deal 3d4 lightning damage to the attacker.
