Id Ooze

Not all oozes are mindless predators capable of little more than ambushing and consuming prey. The id ooze is a thinking, calculating creature with the capacity to carry out complex plots and plans—not always to secure a meal. Left to its own devices, an id ooze is just as content to spend decades or even centuries in introspective philosophical pursuits as it is to crawl through the underground rivers and moist caverns it prefers to call home.

An id ooze can derive sustenance from the consumption of organic material, but without easy access to plants or animals to eat, they can subsist in a state of semi-hibernation for centuries while slowly absorbing residual psychic energies in locations that have been host to powerful emotions, such as long-standing temples that once hosted generations of worshippers, settlements that endured horrific wars or devastating disasters, or even just the home of a powerful occult spellcaster whose thoughts left marks upon the walls long after they moved on.

An id ooze prefers water but is equally at home on land. The slimy creature appears as a patch of water until it attacks, when its gelatinous body piles up on itself to form a single pseudopod that strikes like an angry snake.

The orders must be simple, such as a directive to attack a specific target in preference to another, or to hold ground in a spot to protect a location, or even to adjust its positioning and body to form crude shapes or symbols. A manipulated ooze performs the direction to the best of its ability on its next turn, after which it returns to its normal behavior.

Sidebar - Additional Lore Brain Ooze

Just as id oozes are an evolution of the lesser gray ooze, so do there exist evolutions of id oozes known as brain oozes. While brain oozes aren't much more powerful than an id ooze, they tend to be much crueler and more sadistic in their behavior. Brain oozes appear as disembodied brains that lash out with slimy tentacles. Where the id ooze possesses occult magic that allows them to confuse and hinder thought, brain oozes specialize in controlling thoughts and revels in the resulting feelings of superiority before, inevitably, they consume their mind-controlled victims.

Slimes, molds, and other oozes can be found in dank dungeons and shadowed forests. While not necessarily evil, some grow to enormous sizes and have insatiable appetites.

Sidebar - Related Creatures Amoebas Large and Small

Giant amoebas and amoeba swarms are usually found near each other, as the two oozes are part of the same life cycle. When a giant amoeba grows large enough, it can spontaneously split apart into two separate amoeba swarms, and when an amoeba swarm feeds enough, its individual components can fuse together into a single creature.

Sidebar - Additional Lore Oozing Acid

Many oozes have acidic attacks that can quickly degrade flesh, wood, and even stronger materials. Some believe that oozes are the result of alchemical or magical experimentation run amok, while others postulate that they simply emerged from the natural processes of evolution.

Sidebar - Related Creatures Other Oozes

Many varieties of these nearly mindless predators exist in the world. Some are mere variants, with different colored puddings, jellies, and oozes with little to differentiate them from those presented here other than their habitat. Others are more specialized, or even dangerously intelligent. The shoggoth is one such example, but another variety of deadly and powerful ooze is the thankfully rare blight, a creature composed of protoplasm and eyes that curses entire regions with its presence.
