Livewire Lash-2/2

When you are hit by a spell attack from a
creature within 60 feet of you that you can see,
you can use your reaction to extend a lash of
lightning energy out of the whip and strike the
creature. The target must make a DC 16
Dexterity saving throw. It takes 3d10 lightning
damage on a failed save, or half as much damage
on a successful one. Once you have used this
ability you cannot use it again until you complete
a short or long rest.
