Ooze, Pyronite

With the discovery of the incredible gelatinous explosive called pyronite, it was perhaps inevitable alchemical monstrosities made of the stuff would soon follow. So-called pyronite oozes sometimes spontaneously manifest from stockpiles of pyronite or other powerful explosives, typically amid mana storms or when affected by powerful magic.

Pyronite oozes have an extremely unstable life cycle and are defined by their ability to continuously explode and reform themselves. A pyronite ooze's violent explosions hinder observations, making it difficult to learn anything from the volatile jelly. To complicate matters further, pyronite oozes seem drawn to other unstable alchemical concoctions. Test subjects brought to the Spellscar Desert have been observed bathing themselves in pools of magic-polluted effluvia. Although they typically reform into a single entity after exploding, pyronite oozes bathed in chemicals sometimes remain apart after splitting, creating two independent oozes. Some speculate that an as yet unknown reagent must be essential for the oozes to reproduce on their own.

This explosion can't cause other pyronite oozes to split. After exploding, the ooze splits into two Medium pyronite oozes, each with half the original's HP, which each fly through the air and land 15 feet from the original ooze in a random direction. If no space is unoccupied where the ooze would land, it automatically pushes creatures and objects out of the way to fill a space (the GM decides if an object or creature is too big or sturdy to push).

This explosion can't cause other pyronite oozes to split. After exploding, the ooze splits into two Medium pyronite oozes (see above), but this splitting doesn't deal additional damage.

Sidebar - Additional Lore Unstable Hibernation

After crawling on the ceiling or into some other darkened corner, pyronite oozes sometimes go into a dormant state for days or months. While in this torpor, they become even more dangerous as unstable chemicals seep from the ooze and form into crystals on its surface. These crystals are highly explosive. The ooze's hibernation ends when a slight movement or small spark ignites the crystals, triggering its Exploding Split ability and dealing twice the usual amount of damage.

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.
