Floating Disk
While you are within 20 feet of the disk, it is immobile. If you move more than 20 feet away, it tries to follow you, remaining 20 feet away. It can traverse stairs, slopes, and obstacles up to 3 feet high.
Additionally, you can ride the disc, spending your movement on your turn to move the disc up to 30 feet (following the movement rules above).
Moving the disk in this way is just as tiring as walking for the same amount of time.
