Tazing Grasp

You touch a target with crackling electricity, making a touch spell attack against them. If your touch hits, the target receives 2d6 lightning damage and must make a Constitution saving throw. On a failure, the target is paralyzed for 1 round. This spell may be cast while grappling or being grappled by a target without ending the grapple, doing so guarantees it will hit, and allows it to hit each target involved in the grapple other than you.

At Higher Levels. This cantrip's damage increases to 3d6 at 5th level, 4d6 at 11th level, and 5d6 at 17th level.
