Black Hole

You point somewhere in range,  then close your fist, creating a Blackhole on the target spot. The blackhole is 5x5x5 cubic feet. The blackhole creates a 40 feet radius area around it. Anyone who start their turn, or enter that area, has to succeed in a Strength saving throw, or be pulled towards the blackhole by 15 feet. Anyone inside the area has disadvantage on Dexterity saving throws and can't Dash, or Disengage. If someone enters or starts their round with in 5ft. of the blackhole, they take 51 (10d6 +16) Force Damage.

Casting at higher levels: For each level you cast this spell above level 7, the black hole's size, it's area, and it's pull are all doubled, and when it deals damage, it deals an additional 18 (5d6) Force damage per spell level.
