Shocking Grasp

Make a melee spell attack against a target (1d20+
proficiency+CHA). You have advantage on the
attack if the target is wearing metal armor
(roll 2d20 for the attack and take the higher
number). On a hit, the target takes 1d8
lightning damage and can't make reactions until
the start of its next turn.
When you reach 5th, 11th, and 17th levels, the
damage increases by 1d8 for each one respectively.
