Void Sphere

A frigid globe of necrotic energy streaks from your fingertips to a point of your choice within range, where it creates a 5 ft by 5 ft globe of pure entropy. Each creature within 15 ft. of the globe must make a Strength saving throw. On a failed save, a creature takes 6d6 necrotic damage and is pulled 10 ft. towards the globe. If the creature enters the globe's space, it suffers aditional 4d6 necrotic damage. On a successful save, it takes half as much damage and is not pulled closer towards the Globe.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
