Floating disk

Primary Action. Provokes. Range 5'. Duration: Concentration Summons a 3' diameter 1" wide disk that floats along tethered to the caster at a maximum of 10 squares per round. If you get more than 10 squares away from the disk it disappears. It attempts to float behind the caster at a distance of 5'. The disk floats 2' off the ground, and is subject to falling as per usual. The disk has 10HP with an AR of 4 (all). Attacks against it are at +3 to hit. The disk can support a significant weight (several hundred pounds (300/500/700)), and can be used to prop up wagons, mount battering rams, or a ballista, or a large chest, or drop things off edges. Some Mages even have portable cover for their smaller companions.
