Chill Touch (UA)

You channel the chill of the grave toward one creature you try to touch. Make a melee spell attack against the target. On a hit, the target takes 1d10 Necrotic damage, and it can’t regain Hit Points until the end of your next turn.

This spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
