  • Innate Spellcasting. The yeren’s innate spellcasting ability is Charisma (spell save DC 13). The yeren can innately cast the following spells, requiring no material components:
  • Scrawl Yeren Symbol. The symbol created by the yeren’s Innate Spellcasting trait steals the memories from its victims. At the end of this effect, a creature forgets any interactions with a yeren that occurred over the past 24 hours. The creature’s memory can be restored in the same fashion as though affected by a modify memory spell. A creature that loses its memories to a yeren symbol can’t lose its memories from another yeren symbol for 24 hours.


  • Multiattack. The yeren makes three attacks: one with its bite and two with its claws.
  • Bite (Yeren Form Only). Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) piercing damage.
  • Claw (Yeren Form Only). Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage.
  • Change Shape. The yeren can magically polymorph into a Small or Medium humanoid, into a Large giant, or back into its true form. Other than its size, its statistics are the same in each form. Its equipment, if any, does not transform. If the yeren dies, it reverts to its true form.
  • Steal (Yeren Form Only). The yeren makes a Dexterity (Sleight of Hand) check against the target’s passive Perception to steal a carried or worn item. The yeren has disadvantage on the check to steal a worn item if it is secured (such as worn ring, or item in a closed pouch).


Yeren are rarely found in collusion with other oni, for they have no concerns with the mortal world—beyond indulging in its wilderness. Yeren despoil lands, hunt areas to extinction, and actively push back the advances of civilization. They’re often confused for other, more curious species, such as sasquatches or yetis, but are far more aggressive in nature. A yeren that is seen, enters an almost immediate rage, rushing those that discovered it in a vicious display of claws and bites.

An unseen yeren attempts to steal trinkets and good from those unaware of its presence. A typical yeren oni stands 11 feet tall and weighs around 700 pounds.

Groups of yeren sometimes form in the deepest of wilderness regions, preferring the secluded nature of forests, jungles, or mountains. Unlike peaceful species, the yeren are quick to tax the natural resources of a location, and often relocate. Yeren pick up others of their kind, creating continually growing tribes, though sometimes they come into conflict among one another. They constantly vex innocent kami, whose wards they defile at the earliest opportunity; yeren not being far enough removed from their oni brethren to leave even an unobtrusive kami to its business.

Symbols scrawled across the breadth of yeren territory are the hallmark of these creatures. Yeren can magically imbue their scrawled symbols to befuddle those viewing them. If a yeren views an outsider affected by their scrawled symbols, they’ll quickly break from cover and attempt to steal from the confused target. After taking a few choice items, the yeren retreats back into whatever natural cover is available, and the final magic of its symbol erasing all memory of the yeren from its target. Those of sufficient willpower, can overcome the power of a yeren scrawling, earning the deadly ire of the oni. Yeren fight to the death against creatures who discern their whereabouts and overcome the magic of their symbols, unwilling to risk discovery by others.
