I had fun with these guys in SP. I made an awake Dom9, F3E3D5 Bakemono Kunshu and used him to expand solo. Dom9 for Awe and hit points, D5 for fear, F3 for attack, E3 for a little protection, and it leaves you with only 4 wasted points.
Scales were: Ord3,Sloth3,Heat1,Misfortune2,Drain2.
Sloth 3 still let me recruit as many O-bakemonos as I had gold for, and they're a decent morale troop for another expanding army. One Uba crafted out skull talismans for a load of Mujina assassins, who can then kill most indy leaders. The leaderless indies will route when you send in a single unit (a scout will do, or a Bakemono shaman can hide and preach until the leaders are all dead). Watch out for lizard and amazon provinces, since they like to use bodyguards. Bodyguards = 1 dead Mujina prophet.
