Cursing Touch

Your touch brings a creature closer to death. Make a melee spell attack against a target creature. On a hit, you deal 1d10 necrotic damage to the creature.

If this attack is made against an undead target, you gain temporary hit points equal to the damage dealt.

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