Draining Hold

You grab hold of your target and sap the life from their body. Make a melee spell attack against a target within range, dealing 1d10 necrotic damage on a hit. The target must then make a dexterity saving throw or become grappled. If the spell targets a creature that is grappled by you the spell hits automatically.

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