Eldritch Blood Tentacle Drag

Eldritch power runs through your veins, barely contained by your mortal form. At will, you may succumb to this power and let it flow forth. This is manifested by chanting in deep speech as a writhing cluster of thin black tentacles that burst from your chest towards a target creature.

Tentacle Drag: Target one creature within 30 feet with a melee spell attack roll of (1d20 +2). On a hit you deal 1d6 psychic damage and may pull the large or smaller target creature 10 feet closer. When you hit a creature with Tentacle drag, you may attempt to grapple the target creature (Strength save DC 12). 

The spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
