Castlevania: Sypha's Voltaic Hands (NGtE)

You channel lightning to your fingertips and cause the energy to erupt from them. While concentrating on this spell, you can make a melee spell attack against a creature within 15ft, on a hit the creature takes 4d10 lightning damage and must make a Constitution saving throw. On a failed save the creature is stunned until the end of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
