Dread Shadow's Grasp

With a clawing motion, you cause your shadow to lash out and grasp your target with a giant, dread-inducing spectral claw.  Make a ranged spell attack.  You have advantage if the target does not possess the darkvision trait, preying upon its instinctual fear of the dark.  On a hit, the target takes damage equal to 1d6 + your spellcasting modifier psychic damage, and it can't take reactions until the start of its next turn.

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