This spell creates a disc that floats in the air behind you. You can put
things in it so that it carries them for you. Maximum duration for this spell
is LVL/2 minutes, but in any case it will last at least 2 minutes. You can
also update the floating time by casting the spell at certain disc. Floating
discs are known to be unstable.
You can refer a floating disc with "<owner>'s disc", or "my disc", which works
for the owner.
If the game crashes, you lose the items on the disc. POOF.
Note: You can 'dissipate' or 'dispel' your floating disc if you wish to end
the spell prematurely.
