Black Hole

Create a 30 foot sphere of intense gravity centered on a point within range.

Any creature or object within the radius is pulled 15 feet towards the center into an unoccupied space and must make a Intelligence saving throw or be slowed for one round. While slowed a creature’s armor class is reduced by 2, its movement speed is halved, it has disadvantage on Dexterity saving throws, it can’t use reactions and on its turn, it can use either an action or a bonus action, not both. Regardless of the creature’s abilities or magic items, it can’t make more than one melee or ranged attack during its turn.
