Dark Orb

You send a heavy orb of darkness. Make a ranged spell attack against a creature within range. On a hit, the creature takes 2d6 necrotic damage. The creature must then make a Constitution saving throw. On a failed save, the creature is incapacitated until the end of its next turn.

At Higher Levels. When you cast this spell using a slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st
