Vacuum Sphere

A pitch orb of empty space appears at a point you choose within range. Any creature within a 30 foot radius of the orb must make a Strength saving throw, taking 4d8 force damage on a failure and are pulled 20 feet towards the orb. On a success, the creature takes half damage and isn't pulled. Then, any creature that is within a 20 foot radius of the orb takes 2d8 force damage.

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