As an action, you create a circular, horizontal plane of force, 1 meter in diameter and 2 centimeters thick, that floats 1 meter above the ground in an unoccupied space of your choice that you can see within 9 meters. The disk remains for the duration, and can hold up to 200 kilos. If more weight is placed on it, the spell ends, and everything on the disk falls to the ground.
The disk is immobile while you are within 6 meters of it. If you move more than 6 meters away from it, the disk follows you so that it remains within 6 meters of you. If can move across uneven terrain, up or down stairs, slopes and the like, but it can’t cross an elevation change of 3 meters or more. For example, the disk can’t move across a 3-meter-deep pit, nor could it leave such a pit if it was created at the bottom.
If you move more than 36 meters away from the disk (typically because it can’t move around an obstacle to follow you), the spell ends.
