Curion's Inky Claw of Hadar

An inky clawed hand lashes out from you toward a creature in range. Make a melee spell attack against the target. If the attack hits, the creature takes [roll]1d10[/roll]Psychic damage, and if the creature is Large or smaller, you pull the creature up to 10 feet closer to you. Alternatively you can pull yourself 10 feet closer to the creature you target. This spell can also function as a Grappling Hook (PHB Item).

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