Introduction: Multiversal Menagerie

"Morte. A self-professed 'famous' planar traveler who often poses as a mimir to–"**"Whoa, hey, hey! Zip it there, bud! I don't know who got you a defective mimir, Chief, but I'll tell you what's what from here out."— MortePlanar travelers often find mimirs invaluable in learning about reality and avoiding doom at the hands, claws, fangs, tentacles, proboscises, ovipositors, and other appendages of the multiverse's countless predatory and lethally grumpy inhabitants.

Morte, however, isn't a mimir.

A floating skull with a penchant for speaking his mind and claiming expertise, Morte is one of Sigil's many unique inhabitants and an accomplished explorer of the planes. For the right amount of coin or a future favor, Morte is quick to offer his advice, insights, and commentary on the many inhabitants of the planes. This book contains useful data gleaned from Morte's stories and ramblings. Still, the planes are vast and varied, and what Morte experienced as true might not match all circumstances. Reader beware.

Using a Stat Block

This book is a companion to the Monster Manual and uses a similar presentation. If you are unfamiliar with the monster stat block format, read the introduction of the Monster Manual before proceeding. That book explains stat block terminology and gives rules for various monster traits—information that isn't repeated here.

The Stat Blocks by Challenge Rating table sorts the creatures in this book by challenge rating. Most of these creatures appear in the "Bestiary A to Z" section, but those marked with an asterisk (*) appear in the "Faction Agents" section.

Unusual Attacks and Magic

Some creatures have weapons that deal unusual damage types and spellcasting that functions in an atypical way. Such an exception is a special feature of a stat block and represents how the creature uses its weapon or casts its spells; the exception has no effect on how a weapon or spell functions for a different creature.

Meeting Magic Item Prerequisites

If a stat block contains the name of a class in parentheses under the creature's name, the creature is considered a member of that class for the purpose of meeting prerequisites for magic items.

Stat Blocks by Challenge Rating

Petitioners

Petitioners are former mortals. They've lived, ceased living, and now exist on the Outer Planes. They typically inhabit a plane that shares their alignment or the realm of a deity they worship. Some, however, become lost and wander the planes or make new homes for themselves elsewhere on the Great Wheel.

You can make any creature that isn't a Celestial or Fiend a petitioner by giving it the following traits:

Plane Locked. The creature's creature type changes to Celestial or Fiend (DM's choice), and the creature can't leave the Outer Planes. Portals or magic that allow transport beyond the Outer Planes don't affect this creature.

Soul Shape. A dead petitioner can be returned to life only by the true resurrection spell or the wish spell. If affected by these spells, a petitioner chooses whether to return in its original mortal form or as a petitioner.

Death and the Planes

Mortals that die eventually have their souls return as petitioners in far-flung reaches of the Outer Planes. There, they manifest as idealized versions of themselves. These forms might be similar to the forms they had in life or be those of entirely different creatures. A petitioner or another Celestial or Fiend that is destroyed can reconstitute on a plane that shares its alignment after 100 years, or it might choose to become one with that plane and never return. A creature that re-forms on the planes multiple times becomes increasingly dissimilar from its original mortal form.

Planar Influences

The Outer Planes are home to powerful forces of good and evil, chaos and order. Over time, these forces can alter creatures exposed to them. Due to their proximity to the Outer Planes, the inhabitants of the Outlands' gate-towns and nearby regions often exhibit traits associated with specific Outer Planes. Creatures might also have such traits if they dwell in other realms steeped in the energy of an Outer Plane—whether such a place be in the Outlands, on the Material Plane, or elsewhere.

This section provides customization options for creatures exposed to the energies of the Outer Planes for months or years. Creatures influenced by a plane can have as many or as few of these traits as you choose.

"Anything you think you know about critters from the Material Plane doesn't apply in the Outlands, Chief. Your dog back home ain't nothing like a hound from the Nine Hells or Mount Celestia. Only thing those planar sorts have in common is that neither wants to hear about how you're 'totally a dog person.'"— Morte

Planar Alignment

In addition to the plane-specific traits you can grant a creature, the influence of a plane changes a creature's alignment to match the plane's alignment, as shown on the Outer Plane Alignments table. If a plane a creature is influenced by has more than one alignment, you choose the creature's alignment from the options listed.

Outer Plane Alignments

The Abyss

Creatures influenced by the Abyss gain demonic features, such as horns, scales, and black blood. A creature influenced by the Abyss also gains one or more of following traits of your choice:

Entropy of the Abyss. Whenever the creature deals bludgeoning, piercing, or slashing damage, it can change the damage type to necrotic.

Poison Tolerant. The creature has advantage on saving throws it makes to avoid or end the poisoned condition on itself.

Siege Monster. The creature deals double damage to objects and structures.

Acheron

Creatures influenced by Acheron have rough, scarred skin that resembles armor or pitted metal. A creature influenced by Acheron also gains one or more of following traits of your choice:

Battle Lust. Whenever the creature reduces another creature to 0 hit points with a melee attack on its turn, it gains 10 temporary hit points, and it can take a bonus action to move up to its speed without provoking opportunity attacks.

Corrosive Death. When the creature drops to 0 hit points, it turns into a pile of rust. Any equipment it was wearing or carrying is unaffected.

Pack Tactics. The creature has advantage on an attack roll against a target if at least one of the creature's allies is within 5 feet of the target and the ally doesn't have the incapacitated condition.

Arborea

Creatures influenced by Arborea change color to match the season, and their eyes glint with vibrant hues. A creature influenced by Arborea also gains one or more of following traits of your choice:

Merry Music. Whenever the creature casts a spell or makes a spell attack, the faint sound of merry music can be heard by it and those affected by its magic.

Recklessness. At the start of its turn, the creature can gain advantage on attack rolls during that turn, but attack rolls against the creature have advantage until the start of its next turn.

Arcadia

Creatures influenced by Arcadia gain perfectly symmetrical features and appear eternally youthful or vigorous. A creature influenced by Arcadia also gains one or more of following traits of your choice:

Arcadian Perfection (1/Day). If the creature fails a Strength, Dexterity, or Constitution saving throw, it can choose to succeed instead.

Unshakable Resolve. An invisible, magical aura of confidence and hope surrounds the creature. When another creature that has the frightened condition starts its turn within 5 feet of the creature, the frightened condition affecting it is suppressed for 1 minute. When this suppression ends, the condition resumes if its duration hasn't expired.

The Beastlands

Creatures influenced by the Beastlands gain wilder or more animalistic features, such as larger eyes, thicker fur, or more prominent canine teeth. Beasts influenced by the Beastlands are often affected per the awaken spell—though normal Beasts also typically range through these areas in large numbers. A creature influenced by the Beastlands also gains one or more of following traits of your choice:

Speech of Beast and Leaf (Requires the Ability to Speak at Least One Language). This creature can comprehend and verbally communicate with Beasts and Plants.

Tracker's Eye. The creature can see invisible creatures and objects as if they were visible.

Trackless. The creature leaves no tracks to indicate where it has been or where it's headed.

Bytopia

Creatures influenced by Bytopia appear carved, constructed, or sculpted by an expert artisan. A creature influenced by Bytopia also gains one or more of following traits of your choice:

Phantasmal Dweomer (1/Day). After being in continuous physical contact with a Tiny nonmagical object for 1 minute, the creature can imbue the object with one of the following magical properties (choose one or roll a d6):

• 1–3: Light. The object sheds bright light in a 5-foot radius and dim light for an additional 5 feet.
• 4–6: Sound. The object continuously emits the creature's choice of a nonverbal sound (wind, waves, chirping, or the like). The chosen phenomenon is perceivable up to 10 feet away.

The magical property lasts for 24 hours.

Sounds of Work. Whenever the creature casts a spell or makes a spell attack, the faint sounds of hammering and sawing can be heard by it and those affected by its magic.

Carceri

Creatures influenced by Carceri appear as if they'd been imprisoned underground for a long period; their hair is matted, their nails or claws are long and dirty, and they have marks as if they were bound by chains or rope. A creature influenced by Carceri also gains one or more of following traits of your choice:

Burden of Hopelessness. An invisible, magical aura of hopelessness surrounds the creature. Any other creature that starts its turn within 5 feet of the creature has its speed reduced by 10 feet until it is reduced to 0 hit points, regains hit points, or gains temporary hit points. This reduction never exceeds 10 feet.

Torturous Teleport. An invisible, magic-disrupting aura surrounds the creature. Any creature that teleports into or out of a space within 20 feet of the creature must make a DC 15 Constitution saving throw, taking 16 (3d10) force damage on a failed save, or half as much damage on a successful one.

Vitality Theft. An invisible, magical aura surrounds the creature. Whenever another creature regains hit points within 5 feet of the creature, half of those regained hit points (rounded down) go to the creature generating the aura instead.

Hades

Creatures influenced by Hades often have dour, gray features and feel cold to the touch. A creature influenced by Hades also gains one or more of following traits of your choice:

Aura of Gloom. An invisible, magical aura surrounds the creature. Colors are muted within 30 feet of the creature, and other creatures in that area have disadvantage on Charisma checks and Charisma saving throws.

Extinguish Light. Nonmagical flames within 10 feet of the creature are extinguished.

Larval Rebirth. When the creature dies, it re-forms somewhere in Hades as a larva (see the Dungeon Master's Guide) in 1d10 days.

Shadowy Form. Whenever the creature is fully in darkness or dim light, it becomes semi-incorporeal and gains resistance to bludgeoning, piercing, and slashing damage. If the creature takes radiant damage, its Shadowy Form trait is suppressed for 1 hour.

Limbo

Creatures influenced by Limbo have their appearance shift at each dawn. Their skin might change color, or their features might morph into unnatural, even abstract, configurations. A creature influenced by Limbo also gains one or more of following traits of your choice:

Chaotic Magic. The creature can cast the thaumaturgy cantrip, choosing a magical effect at random. Charisma is the spellcasting ability for this spell.

Churning Chaos. When the creature scores a critical hit or takes a critical hit, chaotic energy bursts from the creature, creating one the following effects (choose one or roll a d6):

• 1–2: Melting Terrain. For 1 minute, the ground within 20 feet of the creature melts into a mud-like texture, becoming difficult terrain.
• 3–4: Miraculous Resilience. This creature gains temporary hit points equal to half the damage the critical hit dealt (rounded up).
• 5–6: Disrupted Gravity. Each creature within 20 feet of the creature must succeed on a DC 15 Constitution saving throw or rise vertically, up to 20 feet, and remain magically suspended there for 1 minute. While suspended in this way, a creature has the restrained condition.

Hidden Slaad. When the creature dies, a slaad tadpole bursts from the creature's chest.

Mechanus

Creatures influenced by Mechanus have angular, symmetrical features, and their skin gains a metallic sheen. A creature influenced by Mechanus also gains one or more of following traits of your choice:

Lightning Rod. Lightning damage can't reduce the creature below 1 hit point. Whenever the creature takes lightning damage, one other creature within 5 feet of it (determined randomly) takes half as much damage.

Viper Nest. When the creature dies, its body disgorges a swarm of poisonous snakes in the same space.

"The planes work on you in all sorts of ways, Chief. Sometimes they'll change your hair or give you spots. Other times they'll turn you into the sort of ugly little worm fiends love to snack on. If you're planning to visit one of the Outer Planes, best to keep your stay short–if you ever want to leave at all."— Morte

Pandemonium

A creature influenced by Pandemonium appears as though it were exposed to cold air for a long time, its skin dry and cracked. Its hair might blow in a phantom wind. A creature influenced by Pandemonium also gains one or more of following traits of your choice:

Hindering Winds. Cold winds sweep around the creature. Any other creature that enters a space within 20 feet of the creature or starts its turn there has its flying speed halved until the start of its next turn.

Wailing Screams. Whenever the creature casts a spell or makes a spell attack, the faint sound of crying and screams can be heard by it and those affected by its magic.

Denizens of the Outlands

As the Outlands are the crossroads of the Outer Planes, travelers in that realm might encounter any creature in existence, many of which have been influenced by other planes. The following sections detail the various creature types likely to be encountered in the Outlands. Use the tables in these sections to inspire encounters and whole adventures in the Outlands.

Planar Exemplars

Some creatures originate on specific Outer Planes. Just as flesh and blood are fundamental to many creatures from the Material Plane, the forces of these creatures' home planes are fundamental to their being. These creatures are manifestations of a plane itself and are altered by other planar influences only under unusual circumstances. The archons of Mount Celestia, the demons of the Abyss, the devils of the Nine Hells, the modrons of Mechanus, and the slaadi of Limbo are just a few examples of such children of the planes.

As a result, it's rare to encounter a group of modrons embracing the chaos of Limbo or devils awash in the natural energy of the Beastlands. It's up to you to decide what creatures are exemplars of their home planes and under what circumstances they might be influenced by other planes.

Aberrations

With their inscrutable biologies and agendas, Aberrations might journey to the Outlands pursuing all manner of schemes or sustenance. Slaadi from Limbo are among the most common Aberrations found on the Outlands.

Outlands Aberrations

Beasts

Varied Beasts roam the Outlands, with many species being long extinct on Material Plane worlds. Plane-influenced creatures and gigantic or idealized animals from the Beastlands are common.

Outlands Beasts

Celestials

Various Celestials watch over the Outlands, particularly those reaches that border the Upper Planes. Angels and archons (presented later in this book) are particularly common. Some seek to prevent fiendish incursions into the plane, while others try to align the Outlands closer to goodly philosophies.

Outlands Celestials

Constructs

Constructs in the Outlands might be the remnants of forgotten civilizations, servants of plane-walking magic-users, or creations with varied important or ridiculous purposes. Among the most common are modrons, mechanical denizens of Mechanus that seek to enforce order on the plane.

Outlands Constructs

Dragons

All varieties of Dragons can be found in the Outlands, though many dwell in isolated reaches away from the plane's gate-towns. Some remain aloof due to their territorial natures, while others seek to avoid the Mausoleum of Chronepsis, home to the legendary dragon Chronepsis (see Sigil and the Outlands for details).

Outlands Dragons

Elementals

Elementals of all varieties can be found in the Outlands. Mephits are common and often serve more powerful creatures as messengers.

Outlands Elementals

Fey

Being close to nature—even the surreal nature of the Outer Planes—Fey dwelling in the Outlands are often influenced by other planes. Fey encountered near a gate-town typically exhibit influences from the town's associated Outer Plane.

Outlands Fey

Fiends

Denizens of the Lower Planes regularly invade the Outlands, seeking to shift the balance of the realm toward evil. The Blood War, the endless conflict between demons and devils, regularly spills onto the plane and can devastate whole regions.

Outlands Fiends

Giants

Giants are common in the Outlands. Many gravitate toward regions influenced by planes corresponding with their alignments, but others seek to find the secret realm of the giant god Annam (see Sigil and the Outlands for details).

Outlands Giants

Humanoids

Humanoids from across the planes travel the Outlands and number among the most common inhabitants of the gate-towns.

Outlands Humanoids

Monstrosities

Monstrosities are common in the Outlands. Due to the influence of the Outer Planes, many behave differently than they might on the Material Plane.

Outlands Monstrosities

Oozes

Oozes often appear in swampy or subterranean reaches of the Outlands or in regions influenced by the Lower Planes.

Outlands Oozes

Plants

Plants in the Outlands often grow to incredible size, produce remarkable flowers or fruit, and exhibit bizarre shapes and colors. Regions influenced by other planes are typically first recognizable by the effect those planes have on vegetation.

Outlands Plants

Undead

Undead often lurk in the dismal reaches of the Outlands, but some wander the land, either seeking places to spend eternity or preying on the living.

Outlands Undead

"Some folks have notions about what sorts of creatures they don't expect to see around the Outer Planes. Like undead, for example–as if they can't grok how souls and vampires and zombies might all wind up on the same infinite planes. What can I say? The planes are wild, Chief–I'm unliving proof."— Morte

Planar Encounters

The following tables present random encounters adventurers might face across the Outlands or in other realms influenced by the Outer Planes. These tables are divided by the alignment of the planes affecting a region. Unless otherwise noted, creatures marked with an asterisk (*) appear in this book, while the rest are described in the Monster Manual.

If you wish to further customize these encounters, use traits detailed in the "Planar Influences" section.

Chaotic Planar Encounters

Evil Planar Encounters

Good Planar Encounters

Lawful Planar Encounters

Neutral Planar Encounters

"Don't go thinking you've got a handle on the planes now, Chief. That's the surest way to find out you don't know the first thing about how they really work."— Morte
