The Magic of the Plane of Ooze
The Oozemaster

Slime Wizard; Mud Witch
Oozemasters are students of a slimy, stinky—and usually sinister—branch of magic that chant goes was invented by the drow. They figured out a way to tap into the power of the para-elemental plane of Ooze, and then mixed in all kinds of Lower Planar skullduggery. Unfortunately knowledge of the darker ways of slime and rot have spread like, well, mould. Including to the plane of Ooze itself, where some of the more nefarious denizens of the plane have found they can tap into the elemental energies even more strongly. Slime wizards have learned to conjure globs of all kinds of fungus, jelly, and slime. They can transform their skin so it melts from their malleable bodies, or gain the powers of black puddings and yellow mould—a power they call the scouring palm. The most dedicated oozemasters can summon great waves of sudden slime, and eventually assume an entirely liquid form, finally at once with the ooze.
It’s also possible to summon an ooze familiar, in the shape of a miniature gelatinous cube. They are practically invisible, and grant acid resistance to their owner—as well as keeping everything nice and clean. You don’t need to be an oozemaster to find this kind of companion, although it probably helps. And as the chant goes—summon yourself a gelatinous cube familiar and it’s a slippery slope to becoming an oozemaster…
