Shadow Bound: When using this spell you will reach shadows out of the ground which grapple onto a creature within a 30 ft radius. The creature will take 1d4 necrotic damage for each turn until it roles a spell save of 16. You can expend a 3rd level spell slot to increase the damage to 1d6 necrotic damage for each turn and a 4th level spell slot to deal 1d8 necrotic damage each turn.
