Pity, for a moment I hoped I had a good reason to ignore the scene.
To recoup:
- RC is a cleric, and doesn't have access to levitation, so he can't have cast it
- A circus isn't going to use a Wondrous item just to levitate a box
- I doubt the circus has in payroll a spellcaster of high enough level and with enough resources to research a permanent levitation spell.
This leaves that such a spellcaster exists in the world, and charges people to cast the spell on their stuff - that is the kind of mundane utility magic never seems to be put to in fantasy worlds (kind of why anyone would even bother manufacturing torches when a light spell effectively lasts forever). While this is possible if unheard of, we know that the dessert traders would rather use a belt of ogre strength to unload heavy stuff than pay for this theoretical permanent levitation spell, so I think the most likely scenario is that no such spell is easily available (alternatively, the one guy that sells it is on a different continent, but if you could make a living out of it, he'd have expanded to all major trade routes by now).
So, all in all, I think we can pretty much assume that, unless there is a cleric spell that does the same thing, no such spell was in use in those scenes.
No, RC was sneaking MitD off on his own.
