Death Touch (TOHS)

Your touch is pain, harming whoever you come in contact with. The deathly power within you is beyond your control, afflicting any who touch your bare skin. By the same token, you can deliver death to your enemies with your touch.

As an action, you make a melee spell attack. On a hit, the target takes 1d10 plus your spell modifier in necrotic damage. 

At Higher Levels. This damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
