Feats
Versatile Unarmed Strike, Throw Anything
Equipment of Note:
Glove of Taarnahm the Vigilant (PGtF)
First of all, the important thing to note is that this character's feet, hands, head, elbows, and knees are all +1 Masterslaying Fleshgrinding Tentacle weapons. (Plus whatever other abilities might seem worth adding; Exit Wound could be nice.)
As Throw Anything doesn't make any mention of unarmed strikes not being valid targets for its use, this character throws all of his extremities at an unfortunate target when he attacks. Versatile Unarmed strike allows Fleshgrinding to work, meaning that all of the thrown extremities can start to burrow into the target.
On the target's round, the victim can either continue to take damage or make Strength checks to rip out the offending limbs.
When the monk's turn comes up again, he can move and attack like normal (since nothing says otherwise, and monks can attack with any part of the body) even though he's just a torso. If the opponent happens to be holding any of the limbs at this period, the monk activates the Masterslaying ability of said limb. In this case, the limb automatically gets a critical hit, begins to grind again, and the opponent must make a Fortitude save or have their brain removed.
Wambo!
