Bone Grinding is supposed to be MR+ to avoid receiving the "Crippled" affliction, according to the manual. I used the following plus Shift + U to test w/ a D9 Vampire Queen, and got 100 Kuro-Onis with various afflictions (limp, blind, mute) but no Crippled (although I didn't check every single Oni). Either the manual is wrong about the "Crippled" affliction or it's a bug.
