This massive plantlike creature has a rubbery, almost spherical body that trundles across the mountainside, resembling a massive toadstool that has learned to walk on a dozen long spines. Suddenly, its back inflates with a thunderous boom, and the creature lifts off the face of the mountain and into the air with shocking grace. Trailing below it are four long, thin, brown tendrils, and three thick branches. The tendrils end in a tiny handlike shape, while the branches end in massive jaws.

Several sages believe that powerful and insane druids created the first Uloriaxes ages ago. Although alien and strange in shape, a uloriax is in fact a rather intelligent creature. They have little interest in society or civilization, but they sometimes drift down into the foothills to raid settlements to add to their collection of magic. Uloriaxes seem to enjoy these raids as much as the plunder; sometimes they return to finish of the slaughter of a village once they have mastered the use of any stolen magic wands and items.

Uloriaxes have numerous mouthlike openings hidden along its body through which they can converse. Their voices are loud and earthshaking, as if a thundercloud had learned to speak. They fly through the air by the generation of prodigious amounts of buoyant gasses that are then vented from these openings to provide propulsion.

The uloriax speaks Common, Auran, and Druidic.
