Iron club-wielding demons from another world, Oni have left their mark upon the material plane. Reclusive and misanthropic, they dwell at the precipice of civilization. They used to guard the entrances to the hells of the earlier age, but as those places have been lost to the ages so have they fallen out of focus. Despite their bad reputation however, Oni are still useful in many ways. To guard places is in an Oni's blood, and many powerful individuals hire, recruit or bind them to do so on their behalf.


While mostly stringent and unyielding in their presumed duty, Oni come in many different types and temperaments, ranging from ill-tempered and sanguine to laconic and lazy.


Oni are usually large and muscular, although they are divided in many different subspecies, denoted by their coloration. The main types of Oni are red, blue, grey, green, purple and black. Most oni employ simple dress, usually limited to a simple loincloth or equally uncomplicated attire.

Red oni are almost ogre-like in appearance, and by far the largest and strongest of the oni. They channel a fearsome fury and are sanguine in temperament, always eager to fight or feast. They are associated with fire, and are capable of breathing it, as well as possessing hides tempered by flame. Red oni are chaotically inclined, and they stand up to 8 feet tall and weigh in at up to 750 pounds.

Blue oni are smaller and leaner in appearance than red oni, and have an elemental connection to water. They are very good swimmers and can take the shape of marine animals, as well as channel nature magic, with an affinity for water. They are immune to cold. Blue oni are neutrally inclined, stand roughly 6 to 7 feet in height and weigh in between 160 and 400 pounds.

Grey oni are close to red oni in size. They are a little bit weaker, but their toughness is legendary. Their skin is the hardest of all oni by far, making them very difficult to injure with physical might alone, and they are the most martially inclined of the oni as well. They have access to maneuver-like abilities and are immune to acid. Grey oni are lawfully inclined, stand roughly 6 to 6 and a half feet in height and weigh in at between 180 and 300 pounds.

Green oni are the leanest and most dextrous of oni, and are capable of melding into the background of any forestal area with supernatural ease. Their breath is poisonous and their spell-like abilities manipulate nature. They are skillful hunters that will chase their quarry obsessively wherever it goes. They are immune to electricity and poison. Green oni are evilly inclined, stand about 6 feet tall, and weigh in at roughly 160 pounds.

Purple oni are the smallest and fairest of oni, and are roughly human-sized. They wield powerful arcana and are immune to spells, but are rather weak physically and have no further immunities. They are chaotically-aligned and, stand roughly 5 and a half feet in height, and weigh in at 140 pounds.

Black oni are the most insidious and evil of the oni, and have a powerful connection to death magic and necromancy. Their spell-like abilities allow them to animate the and control the dead, and they are immune to negative energy, negative levels and death effects.

White oni are generally neutral and free flowing souls. They highly value training, meditation, and free spirit. They have a powerful connection to the air and wind currents, using the vast skies to summon ride-able clouds, run through the air, fire bullets of wind from their fingers, or protect themselves with a blowing winds. They are similarly agile and dextrous to green oni, although not as lean. They tend to stand between 5 and a half feet tall to 7 feet tall.


Usually non-good.


Volcanic areas (red), places near water (blue), mountains (grey), forests and jungles (green), dungeons (purple) gravesites and crypts (black), or clouds and pinnacles of the world (white).


Oni speak oni, a pidgen of Old Infernal and elemental languages. Oni tongue has many inflections and hidden meanings, and different species of oni often use different words and phrases to denote the same thing. Red oni speech has Ignan influence, blue oni speech has Aquan influence, grey oni speech has Terran influence, green oni speech has Sylvan influence, and purple and black oni speech has Draconic influences. Creatures that speak these corresponding languages can roughly understand an oni's speech. Creatures that speak oni can understand an oni regardless of what languages it loans from.

Racial Traits[edit]

All subraces of oni possess the following general racial traits.

  • Oni base land speed is 30 feet.

  • +8 Strength, +2 Constitution, -2 Intelligence. These ability score modifications stack with oni general traits.

  • Powerful Build: A red oni's physical stature lets it function in many ways as if it were one size category larger. Whenever it is subject to a size modifier or special size modifier for an opposed check (such as during grapple checks, bull rush attempts, and trip attempts), it is treated as one size larger if doing so is advantageous to it. It is also considered to be one size larger when determining whether a creature’s special attacks based on size (such as improved grab or swallow whole) can affect you. It can use weapons designed for a creature one size larger without penalty. However, it retains the space and reach of a Medium creature.
  • Fast healing 5.
