Black Hole

You condense gravity into an immeasurably dense orb at a point you can see within the spell's range. The orb fills a 10- foot radius sphere around it with darkness, which no light, magical or mundane, can illuminate. When a creature enters within 30 feet of the orb for the first time on a turn or starts its turn there, it must make a Strength saving throw or be pulled 10 feet toward the orb. When a creature enters within 5 feet of the orb for the first time on a turn or starts its turn there, it must make a Constitution saving throw, taking 10d10 bludgeoning damage on a failed save or half as much on a successful one. The orb's gravitation makes moving away from it incredibly difficult. While within 10 feet of the orb, a creature moving away from the orb must spend 4 feet of movement for every 1 foot it moves. While within 30 feet of the orb, a creature moving away from the orb must spend 2 feet of movement for every 1 foot it moves. In addition, unsecured objects that are completely within the area of effect are automatically pulled into orb. Small nonmagical objects that come within 5 feet of the orb are immediately destroyed.
