So I realize you can't use a claw/bite/ect and increase or do unarmed damage. If I make natural attacks Claw/claw/claw bite it must do damage and use attack rolls for claw/claw/bite stats. However I have been thinking of making a white haired witch monk (which is a pretty standard eastern arctype) Can I use the hair limb for my monk attacks if I forgo the natural attack all together. So I would be using the prehensile hair as I would my hands/feet/ect when making unarmed attacks.
My Justification for this is just because I have a claw doesn't mean I can't use that arm/hand and do unarmed attacks. Prehensile hair works as an extra appendage so couldn't I use it to strike with the monks unarmed attacks just like any other limb?
