Vaultbreaker Ooze

Though many oozes hunt among the dreary confines of underground caverns, dungeons, and abandoned ruins, others seek to quell their hunger in areas well-trafficked by civilized creatures. The aptly named vaultbreaker oozes exhibit a mindless compulsion to feed on and digest precious metals. When near precious metals, the ichor exuded from their metallic plasm tarnishes black and forms small, jagged crystals that dot the oozes' surface. Like a strange biological compass, these crystals point vaultbreaker oozes to their next meal.

Though mindless, these strange oozes exhibit an innate instinct for picking and bypassing locks to reach their meals by inserting a gelatinous pseudopod into a keyhole and then hardening the appendage into solid metal, forming a tool similar to a skeleton key.

Vaultbreaker oozes can often be found in cities where tectonic instability has created fissures and cracks, allowing them to infiltrate basements, vaults, and underground chambers that may contain treasure. When rumors of vaultbreaker ooze sightings surface, banker consortiums, Abadaran priests, and even local thieves guilds offer hefty sums to have the dangerous oozes destroyed—though some might instead offer a bounty for their capture.

Sidebar - Advice and Rules Tracking a Vaultbreaker Ooze

A vaultbreaker ooze that has recently fed on precious metals leaves behind a faint trail of smeared, molten leaf of what it ingested (often gold or silver). A character who succeeds at a DC 23 Perception check can detect the strange trail, though following the ooze using this residue requires a successful DC 26 Survival check to Track. A trail of metal leaf left by a vaultbreaker ooze flakes away after 1d4 days.

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.
