Shocking Grasp

Instantanious | 1 Action | Touch
You have advantage on the attack roll if the
target is wearing armor made of metal. On
a hit, the target takes 1d8 lightning damage,
and it can't take reactions until the start of
its next turn.
The spell's damage increases by 1d8 when you
reach 5th level (2d8), 11th level (3d8), and 17th
level (4d8).
