Oozes are simple-minded, amorphous creatures that live only to consume. Some oozes take on elemental traits, such as the heated kind known as a molten ooze. It is mottled with red and black and speckled with orange flecks, and is easily mistaken for lava itself. Its body is dense, viscous, and resilient against harm. These oozes are extremely dangerous for novice adventurers.

When a molten ooze moves, it rolls like a slow, fiery bubble, or flows like a slithering trickle of lava. Any organic material it moves over is dissolved, and any remains are seared to ash, which the ooze will also consume. It leaves stone and metal unharmed.

Molten oozes typically dwell within volcanoes or fiery caverns beneath the earth, although some lurk in alleys and abandoned buildings in the City of Brass, the efreeti capital in the Elemental Plane of Fire. Some efreeti even keep these oozes as pets, using them to dispose of waste and to clean surfaces in their palaces. In a pinch, the oozes can even serve as defenders against enemies, but anyone who keeps an ooze as a pet knows that the ooze can't distinguish friend from food, especially in the chaos of a frenzied battle.
