Attack Disk

This spell creates a circular, horizontal plane of force, 3 feet in diameter and 1 inch thick, that floats around 5 feet above the ground in an unoccupied space of your choice that you can see within range. The disk remains for the duration and can hold up to 500 pounds. If more weight is placed on it, the spell ends, and everything on the disk falls to the ground.

When you conjure the disk and on any subsequent turn, you can command the disk to move up to 30 feet to any point within 30 feet of you. You can not move the disk more than 30 feet away from you. If you move more than 30 feet away from it, the disk follows you so that it remains within 30 feet of you. It can move across uneven terrain, up or down stairs, slopes and the like, but it can't cross an elevation change of 10 feet or more. For example, the disk can't move across a 10-foot-deep pit trap, nor could it leave such a pit if it was created at the bottom.

If you move more than 120 feet from the disk (typically because it can't move around an obstacle to follow you), the spell ends.

If you move the disk to a place where it would end its movement in a creature's space that creature must make a strength or dexterity saving throw (creature's choice). If the creature fails the saving throw, it takes 4d10 force damage + 1d4 bludgeoning damage for every 100 pounds that the disk is carrying. Once the disk deals damage in this way, the spell ends. Any creature that fails the saving throw by 5 or more is knocked prone and restrained if the disk is carrying at least 300 pounds.
