A dark streak trail of shadows bursts from your pointing finger to a point you choose within range and then expands into a black hole. Each creature in a 35-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d8 necrotic damage on a failed save and gets pulled to the center of the black hole for the duration of the black hole, or takes half as much damage on a successful one without being pulled in. A creature which is pulled into the black hole can not take actions, bonus actions, or reactions, and must make a DEX saving throw contested by your spell DC at the end of their turn. If they succeed, they pull themself out of the black hole.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
