Tazer Touch

Lightning springs from your hand 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 2d6 lightning damage, and must succeed on a constitution saving throw or be stunned until the end of its next turn.

This spell can be cast using spell slots of higher level. The spell's damage increases by 1d6 for each slot used above 1st level.
