Battery Powered Defibrillator

This defibrillator has 6 charges. While holding it, you can use an action to expend 1 or more of its charges to cast the Shocking Grasp spell. Lightning springs from the pads to deliver a shock to a creature you try to touch. Make a melee spell attack against the target. 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.

You can increase the damage to 2d8 by expending 2 charges.

If you expend the defibrillator's last charge, roll a d20. On a 1, the defibrillator sparks, sizzles and is useless. Otherwise a replacement battery must be found.
