Swamped

You can't actually tell what it is, only that it's large, round, made of metal, and dripping.

It seems to be climbing out of the pit on thin spindly legs, showing no particular hurry despite the fact that a wizard flew down moments before.

What could this thing's purpose be? It doesn't appear to be a weapon, but you can't see any tools on it either. Are they stored inside the sphere that seems to be its main body? Or does it have some other function?

You don't have much time to speculate, however, before you see flashes of light coming from the pit. The wizards must be fighting now.

So what are you going to do?
