Surgeon's Strike

You attack a creature as part of this cantrip and force it to make a Constitution saving throw. On a failed save, it takes 1d4 piercing damage and the next attack against the target has Advantage until the start of your next turn.

The damage increases by 1d4 when you reach certain levels: 5th level (2d4), 11th level (3d4), 17th level (4d4).
