Monsters
Notes from the Nails: the 5e Monster Manual doesn’t have many oozes. Some say it doesn’t have enough oozes. Here’s a selection of new and revived jelly monsters to dissolve your players…
Amorphous Antagonists and Sinister Slimes
When we play D&D in a fantasy setting, it’s easy to take the existence of oozes for granted. There they are, right there in the Monster Manual, between oni and orcs. Just another sack of hitpoints for your players to beat up, right?
Wrong. Encountering an ooze should be as terrifying for your players as it is for their characters. Put yourself in their shoes: a pool of liquid on the ground suddenly comes to life and attacks! It can’t be reasoned with, feels no pain, and cutting it up just means there’s more of it to fight! Maybe it’s corrosive. Maybe it’s poisonous. Maybe it absorbs magic. Stumbling upon an ooze should be instantly turning run-of-the-mill dungeon delving into a deadly struggle to survive.
Even worse, encountering an ooze will nearly always be a surprise. An adventuring party will very rarely expect to be fighting oozes, because oozes are not innately evil (or indeed good, if playing an evil campaign). They don’t build fortresses and plot villainous schemes, nor do they invade or rampage like orcs and gnolls. They’re just there, doing their own thing, with no heed for whomever else they might share their lair with… except to the extent that they may be edible.
Thus, oozes make great random/wandering monsters, providing a useful change of tone to scenarios that might otherwise involve multiple battles against the same kind of enemy. You can also drop them into exploration-heavy scenarios, treating them almost more like a hazard to be avoided, rather than a monster to be fought.
The stat blocks below aim to offer you a wider variety of oozes to throw at your players, especially at higher challenge ratings than the Monster Manual caters to. One thing that many of these have in common is that they get more dangerous the longer a fight goes on, engulfing, draining and inflicting status effects of the PCs while slowly wearing them down. These kinds of effects ratchet up the tension and encourage players to feel more of what their characters are feeling.
Oozes
Oozes defy the conventions of other living things. Even without organs, skin, senses, or any discernible anatomy, oozes thrive where other creatures would starve by having a simple, yet effective survival strategy: envelop and digest anything within reach.
Simple Predators. Much like molds and fungi, oozes thrive in dark, moist spaces. They prowl around in the dark, earless and eyeless, relying on vibration alone to seek out movement and possible prey. Oozes are mindless, acting on rudimentary instinct to find and consume.
In a fiendishly clever adaptation, oozes require no special method to digest eat or digest; they simply envelop organic material into their bodies and slowly dissolve it. The entire ooze is digestive – a mass of acidic slime that can break down any organic thing into its component parts, given enough time. Different oozes can digest different materials, but all oozes can liquefy an adventurer.
Adventuring Hazards. Oozes unwittingly participate in the defense of dozens of ancient tombs. Veteran adventurers warn that tidy paths in decrepit tombs shouldn’t be trusted. If a place seems too clean, it might be swept routinely by a patrolling ooze.
Moreover, a hapless ooze might compound the deadliness of an already hazardous trap. A routine pit fall is made downright lethal when a black pudding has already fallen down its bottom.
Fortunately for adventurers, the slow death an ooze provides affords greater opportunity for rescue. It’s far easier to pull someone from the belly of an ooze than it is to pull them from the belly of a dragon, after all.
Ooze Nature. An ooze doesn’t require sleep.
Arcane Ooze
The crackling, green protoplasm of an arcane ooze spells terror for magic users. The arcane ooze seeks out and devours arcane energy, ignoring any other targets that might be in the area. Some wizards fear that one day, arcane oozes will consume all the magic in the world, ending wizardry forever.
If that were to happen, however, some would claim that it was a self-inflicted demise. There is no proof, but widespread conjecture suggest that the first arcane oozes were created by a group of wizards deliberately, as a weapon to be deployed against a rival group. If so, they definitely got more than what they bargained for.

Magic Resistance. The ooze has advantage on saving throws against spells and other magical effects.
Amorphous. The ooze can move through a space as narrow as 1 inch wide without squeezing.
Actions
Constrict. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 20 (4d6 + 6) bludgeoning damage, and a Large or smaller target is grappled (escape DC 17) . Until this grapple ends, the target is restrained, and the ooze can’t constrict another target.
Dissolve. One creature grappled by the ooze takes make a DC 19 Constitution saving throw, taking 18 (4d8) acid damage, or half as much on a successful one.
Spell Siphon (Recharge 6). The ooze makes one dissolve attack against a Large or smaller target it is grappling. If the attack hits and the target is a spellcaster, the target loses its highest level unused spell slot and the ooze regains hit points equal to 5 times the slot level.
Chilling Fog
A chilling fog is an unusual species of ooze that arises spontaneously on a battlefield the day after a great battle has been fought. Specifically, the chilling fog is a living manifestation of the residual energies left by spellcasters using the fog cloud and cone of cold spells, fused with the life force of hundreds of dying soldiers.

Magic Resistance. The chilling fog has advantage on saving throws against spells and other magical effects.
Ooze Cloud. The chilling fog takes up its entire space, which is heavily obscured. Other creatures can enter the space, but a creature that does so is subjected to the chilling fog’s Engulf and has disadvantage on the saving throw.
Creatures inside the chilling fog cannot be seen due to the fog’s obscuring effect.
A creature within 5 feet of the chilling fog can take an action to pull a creature or object out of the ooze. Any creature making such an attempt takes 14 (4d6) cold damage.
The chilling fog can move through any object that allows air to pass through it, though it moves through passages with a diameter smaller than one inch as if it were difficult terrain.
Slow Fall. The chilling fog is immune to falling damage. If it is above ground level, it sinks gently at a rate of 60 feet per round.
Innate Spellcasting. The chilling fog’s innate spellcasting ability is Constitution (spell save DC 13). It can innately cast the following spells, requiring only no material components:
At will: fog cloud, ray of frost
3/day: cone of cold
Actions
Engulf. The chilling fog moves up to its speed. While doing so, it can enter a large or smaller creature’s space. Whenever the chilling fog enters a creature’s space, the creature must make a DC 13 Dexterity saving throw.
On a successful save, the creature can choose to dodge 5 feet back or to the side of the chilling fog. A creature that chooses not to dodge suffers the consequences of a failed saving throw.
On a failed save, the chilling fog enters the creature’s space, and the creature takes 27 (6d8) cold damage and is engulfed. The engulfed creature must make a DC 13 Constitution save or be paralyzed until it leaves the chilling fog ‘s square, and takes 36 (8d8) cold damage at the start of each of the fog’s turns.
If the chilling fog leaves a creature’s square on the same turn it enters, they may only make an opportunity attack against it if they opted not to make a save against being engulfed in the first place. The chilling fog may not attempt to engulf the same creature twice in one turn.
Fire Flan
These bright orange fire flans, roughly the size of a dwarf, make their homes in the hottest of places: deserts, volcanoes and the Elemental Plane of Fire. They swarm any creature foolish enough to approach them and can be terrifying foes, but can be defeated by icy magic, which rapidly saps their strength.

Actions
Pseudopod. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) bludgeoning damage plus 7 (2d6) fire damage.
Glitterfire
Like the chilling fog, glitterfires appear on old battlefields. These stormy clouds of smoke and lights are created where warring mages have cast the spells glitterdust, faerie fire and fireball to illuminate and destroy their targets. The glitterfire drifts aimlessly, a mindless echo of humanoids’ destructive will.

Magic Resistance. The glitterfire has advantage on saving throws against spells and other magical effects.
Ooze Cloud. The glitterfire takes up its entire space. Other creatures can enter the space, but a creature that does so is subjected to the glitterfire’s Engulf and has disadvantage on the saving throw.
Creatures inside the glitterfire can be seen but have half cover. They cannot benefit from invisibility or take the Hide action while inside the glitterfire.
A creature within 5 feet of the glitterfire can take an action to pull a creature or object out of the ooze. Any creature making such an attempt takes 10 (3d6) fire damage.
The glitterfire can move through any object that allows air to pass through it, though it moves through passages with a diameter smaller than one inch as if it were difficult terrain.
Slow Fall. The glitterfire is immune to falling damage. If it is above ground level, it sinks gently at a rate of 60 feet per round.
Innate Spellcasting. The glitterfire’s innate spellcasting ability is Constitution (spell save DC 13). It can innately cast the following spells, requiring only no material components:
At will: faerie fire, firebolt
3/day each: fireball, glitterdust (see New Spells – Fey — coming soon)
Actions
Engulf. The glitterfire moves up to half its speed. While doing so, it can enter a medium or smaller creature’s space. Whenever the glitterfire enters a creature’s space, the creature must make a DC 12 Dexterity saving throw.
On a successful save, the creature can choose to dodge 5 feet back or to the side of the glitterfire. A creature that chooses not to dodge suffers the consequences of a failed saving throw.
On a failed save, the glitterfire enters the creature’s space, and the creature takes 21 (6d6) fire damage and is engulfed. The engulfed creature must make a DC 13 Constitution save or be blinded until it leaves the glitterfire’s square, and takes 28 (8d6) fire damage at the start of each of the glitterfire’s turns.
If the glitterfire leaves a creature’s square on the same turn it enters, they may only make an opportunity attack against it if they opted not to make a save against being engulfed in the first place. The glitterfire may not attempt to engulf the same creature twice in one turn.
Limon Brûlée
The disturbingly delicious limon brûlée, or burnt slime, has the appearance and texture of custard and is unique among oozes in that it is not usually a predator, but a prey. When forced to defend itself, it extends goopy pseudopods and flails wildly, or gathers into a pack in the hopes that the predators will eat only a few slimes and leave the others in peace.

Delicious. If a creature kills the limon brûlée with a melee attack, it must succeed on a DC 11 Wisdom saving throw or spend its next turn ravenously eating the ooze. While eating, the creature can’t move or take actions, bonus actions, or reactions.
Sweet Scent. Any creature that attempts a Wisdom (Perception) check using their sense of smell while within 300 feet of the limon brûlée automatically detects its presence, but the DC to detect anything else is increased by 5.
Actions
Pseudopod. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) bludgeoning damage.
Mustard Jelly
The noxious mustard jelly is less common than its yellow cousin, the ochre jelly, but the two are found in the same general environments. Encountering both species at once is an adventurer’s worst nightmare, as one is immune to swords and axes – and the other spears and arrows. Working in tandem, the quicker mustard jellies attack first, slowing interlopers and fixing them in place, while the more powerful ochre jellies follow in afterwards, overwhelming all but the most stalwart of fighters.

Amorphous. The jelly can move through a space as narrow as 1 inch wide without squeezing.
Actions
Pseudopod. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage plus 9 (2d8) acid damage. In addition, the target must succeed on a DC 12 Constitution saving throw. On a failed save, the target’s speed is halved for 1 minute. In addition, the creature can’t take reactions, and it can take either an action or a bonus action on its turn, not both. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Thunder Flan
Small and unassuming, thunder flans appear in areas of intense electrical activity, or after heavy thunderstorms. Although they are one of the weakest types of ooze an adventurer might encounter, they can prove surprisingly dangerous thanks to their ability to strike at range with jolts of lightning – or heal themselves with the same technique.

Actions
Jolt. Ranged Magic Attack: +4 to hit, range 60 ft., one target. Hit: 6 (1d12) lightning damage.
Void Ooze
Void oozes are horrible creatures, native to Shadowfell, that defy all logic. Floating through the air like oily clouds, they scan the ground for prey with a multitude of eyestalks. These monsters have formed a symbiotic relationship with the wandering undead that populate their realm, using packs of skeletons and zombies to occupy their prey while they drain their life force with black pseudopods. In return, the undead are able to draw sustenance from the negative energy field that surrounds a void ooze, becoming stronger and more vigorous the longer they spend in its shadow.

Shadow Shield. The void ooze is surrounded at all times by a shifting cloud of darkness. Characters that rely on sight have disadvantage on attacks against the ooze. While the ooze is in dim light or darkness, it can Hide as a bonus action.
In addition, the shield is infused with negative energy. At the start of each of the ooze’s turns, each creature within 5 feet of it takes 10 (3d6) necrotic damage, except for undead, which recover 3d6 hit points instead. A non-undead creature that touches the ooze or hits it with a melee attack while within 5 feet of it takes 10 (3d6) necrotic damage.
Actions
Draining Pseudopod. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) bludgeoning damage plus 9 (2d8) necrotic damage. The target must succeed on a DC 19 Constitution saving throw or its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the creature finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.
White Pudding
White puddings are a subspecies of black pudding found only in arctic seas. They lurk in the water, indistinguishable from a mundane ice floe, ambushing any creature that gets too close. By necessity, they feed mainly on marine mammals and large fish, but are strongly attracted to humanoid flesh when it is nearby.

Magic Resistance. The pudding has advantage on saving throws against spells and other magical effects.
Amorphous. The pudding can move through a space as narrow as 1 inch wide without squeezing.
Corrosive Form. A creature that touches the pudding or hits it with a melee attack while within 5 feet of it takes 4 (1d8) acid damage. Any nonmagical weapon made of metal or wood that hits the pudding corrodes. After dealing damage, the weapon takes a permanent, cumulative -1 penalty to damage rolls. If its penalty drops to -5, the weapon is destroyed. Nonmagical ammunition made of metal or wood that hits the pudding is destroyed after dealing damage.
The pudding can eat through 2-inch-thick, nonmagical wood or metal in 1 round.
False Appearance. When swimming, the pudding is completely indistinguishable from an ice floe.
Actions
Pseudopod. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage plus 18 (4d8) acid damage and 9 (2d8) cold damage. In addition, nonmagical armor worn by the target is partly dissolved and takes a permanent and cumulative -1 penalty to the AC it offers. The armor is destroyed if the penalty reduces its AC to 10.
Reactions
Split. When a pudding that is Medium or larger is subjected to piercing or slashing damage, it splits into two new puddings if it has at least 10 hit points. Each new pudding has hit points equal to half the original pudding’s, rounded down . New puddings are one size smaller than the original pudding.
Magitech Oozes
Scientists may not necessarily agree on whether or not society is heading for a grey, gooey demise, but either way, the oozes of the future are terrifying beasts. Some of them are even sentient!
Nanite Swarm
Swarms of nanorobots, each individual too small to be seen with the naked eye, behave almost exactly like classical oozes. Nanite swarms crawl and spread, dissolving metal and absorbing biological matter with impunity. The main difference lies in their intelligence: nanite swarms make use of complex neural networks that give them immense computational power, despite individual nanites being relatively simplistic. Thanks to this, nanite swarms are capable of understanding and following instructions, which (usually) prevents them from consuming things they shouldn’t.

Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a microscopic nanorobot. The swarm can’t gain temporary hit points.
Resources. When the nanite swarm attacks a creature or object, it breaks down and stores some of their chemical matter in the soupy grey medium that surrounds the swarm. This is represented by a pool of Resource Points, which can be expended to use certain actions, as detailed below. A nanite swarm can store up to 6 Resource Points at any one time.
Actions
Recycle. Melee Weapon Attack: +4 to hit, reach 0 ft., one target in the swarm’s space. Hit: 15 (6d4) necrotic damage and the swarm gains 1 Resource Point. If the swarm has half of its hit points or fewer, the attack deals only 7 (3d4) damage.
Reconstitute (Costs 1 Resource Point). A creature or object in the swarm’s space (other than the swarm) regains 11 (2d10) hit points.
Self-Repair (Costs 1 Resource Point). The swarm regains 7 (2d6) hit points.
Radioactive Goo
The interaction between magic and technology is at its most sickening in the radioactive goo. Produced by machines and animated by magic, these hazardous monsters are a threat to all around them. Hunters who specialize in the tricky business of ooze eradication collect exorbitant fees every time a radioactive goo appears.

Adaptive Mutation. Whenever the goo takes damage, it gains immunity to that type of damage until the end of its next turn, or until it takes another type of damage; the goo can gain immunity to one damage type at a time as a result of this feature.
Radiation Hazard. At the start of each of the goo’s turns, each creature within 15 feet of it takes 10 (3d6) poison damage.
Actions
Pseudopod. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 17 (4d6 + 3) bludgeoning damage. In addition, the target must make a DC 14 Constitution saving throw or be poisoned for 1 hour. This poisoning cannot be cured by any means short of greater restoration spell.
Irradiate. Ranged Weapon Attack: +5 to hit, range 60 ft., one target. Hit: 7 (2d6) necrotic damage and the target must make a DC 14 Constitution saving throw. On a failure, the target has disadvantage on ability checks using a randomly determined ability score for 1 minute. It can repeat the saving throw at the end of each of its turns.
Slime Person
An industrial accident was responsible for the creation of slime people: small, amorphous folks with stubby little arms and a surprisingly militaristic culture. Now, nations of slime people colonize the dank corners of the world, thriving in sewerage systems, undersea caverns and rotten swamps. They are generally benign and friendly with other humanoids, since they are not competing for the same territory or resources, but anyone who believes their soft bodies might make them pushovers will find themselves sorely mistaken.
