PFS StandardMountain Oni

Mountain oni are the most common oni and often considered the least sophisticated. While other oni might have a stronger connection to the spiritual world, mountain oni have little interest in anything beyond satisfying their relentless appetites. Sloth and gluttony are common vices among mountain oni, which can allow them to coexist with nearby villages so long as they're well fed, but more ambitious mountain oni can often be found leading ogre war parties or orchestrating violent bandit raids. It's rare for mountain oni to live solitary existences, but those who do prefer to maraud the countryside or exploit villages and hoard the spoils for themselves.

They make a tetsubo Strike. On a success, the target takes an additional 1d10 sonic damage. Each creature in a 10-foot emanation around the target, other than the oni, take this damage as well and is pushed 5 feet away from the target.

Sidebar - Advice and Rules Tetsubo

A mountain oni wields a tetsubo, which appears in Lost Omens Tian Xia Character Guide. This uncommon martial weapon costs 3 gp, deals 1d10 bludgeoning damage, has 3 Bulk, and require two hands to use. Tetsubo are in the club weapon group and have the razing, shove, and sweep traits. The razing trait means that whenever the weapon damages an object, the object takes an amount of additional damage equal to double the number of weapon damage dice.

Oni

Source Monster Core pg. 252
Oni are large, brutal creatures originating in Tian Xia who resemble humanoids with brightly colored skin, tusks, and horns. Though commonly mistaken for fiends, the first oni were originally kami, tutelary nature spirits. These kami suffered a terrible trauma, losing their sacred wards to dramatic disasters or the callousness of others, and as a result transformed into the violent creatures they are today. While some believe that oni can be spiritually placated through proper ritual worship that transforms them back into kami, many of these would-be saviors fall to oni's notorious brute strength, flesh-rending teeth, and command of storms.

Oni possess the ability to disguise themselves as other humanoids. They are rarely creative in their disguises, often choosing a specific appearance similar to their oni form and sticking with it. This simplicity catches many by surprise, however, as people assume oni are limited to a single alternate form, which is by no means the case.

Sidebar - Additional Lore Kishin Oni

The mightiest oni are powerful quasideities known by the title of kishin, possessing unique powers and isolated mortal domains. The most powerful is Inma, the Empress of the World, but Akuma the Horned King, Murona the Dark Mother, and Nataka the Red King are also worshipped.

Sidebar - Additional Lore Oni Origins

The first oni originated in the nation of Minkai on the continent of Tian Xia. Whether due to prevalent local kami— particularly in the mist-shrouded Forest of Spirits—or its peoples' faiths, Minkai is a hotbed of oni activity

Sidebar - Related Creatures Other Oni

Different oni exist across the continent of Tian Xia. Village oni mask their golden skin and four-fingered claws in human form. Other oni include night oni, which lurk in darkness and smoke, void oni, with their malevolent shadowy flames, and the awesomely powerful storm oni.
