Dark Binding

Fires a bolt of dark energy towards a target, binding them to the ground. Make a ranged spell attack against a creature within range. On a hit, the target takes 6d8 necrotic damage, their speed becomes 0 and they can’t benefit from any bonus to its speed until the end of it's next turn.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
