Shocking Grasp

Lightning springs from your hand. Make a
melee spell attack. You have advantage on
the attack if the target is wearing metallic
armor. It takes 1d8 lightning damage, and
can't take reactions until it's next turn.
The spell's damage increases by 1d8 when
you reach 5th level (2d8), 11th level (3d8),
and 17th level (4d8).
