Electric Shock

You deliver a shock to a creature by touch that disturbs its coordination momentarily. The target must succeed on a Constitution saving throw. On a failed save, the creature must suffer 1d6 lightning damage and suffer the Stunned. on a successful save, the target takes half damage and is not Stunned. If the target is unconscious, it automatically fails the saving throw, but instead of taking damage, it is stable.

Cantrip Upgrade. The damage increases by 1d6 when you reach levels 5 (2d6), 11 (3d6), 17 (4d6), and 20 (4d8)
