Oriental Adventures
Mamonos are hideous shapechangers with a strong resemblance to doppelgangers. In their natural form, they are skin-less creatures of bone and muscle, with a single eye and a gaping, spiderlike maw in their abdomens. Their arms end in serrated blades of bone, each as deadly as a wakizashi.
Like doppelgangers, mamonos use their natural abilities of mimicry and deception to infiltrate human society. Unlike doppelgangers, however, they are motivated by a deep loathing of humanity rather than simple self-interest, and they delight in flaying their victims before devouring their eyes, liver, and other soft tissue.
Mamonos speak Shadowlands and Rokugani (Common).
Combat
In human form, a mamono attacks with a weapon or unarmed, but if it is severely threatened it reverts to its natural form and uses its formidable natural weaponry.
Taint (Su): Those hit by a mamono's bite or claw attack must succeed at a Fortitude save (DC 17) or have their Taint score increased by 1.
Alter Self (Su): A mamono can assume the shape of any Small or Medium-size humanoid. This works like alter self as cast by an 18th-level sorcerer, but the mamono can remain in the chosen form indefinitely. It can assume a new form or return to its own as a standard action.
Invisibility (Sp): A mamono can use the invisibility spell at will.
Rejuvenation (Su): If a mamono is killed at night, it reawakens in 2 hours, completely healed and very angry. The only reliable way to kill a mamono is to cut it into three or more parts and bury them separately. A mamono cannot rejuvenate if killed during the day or exposed to direct sunlight.
Light Sensitivity (Ex): When exposed to the light of the sun a mamono takes 1d8 points of damage per minute of exposure.
