Multi-Attack Feat from Bestiary

[Rithralas]

I have a player that wants to take subject feat. Rolled a half-orc, and wants to get the most out of his bite.

The feat clearly states a pre-req of three natural attacks. My argument is that the half-orc only has one natural attack (the bite) and the otehr limbs would be considered unarmed attacks. Am I correct?

Yes, you are correct. Now if the player finds a way to grab Claws (2 levels of ranger is easiest) then they would qualify.

[concerro]

Unarmed attacked are not natural attacks. You are correct.

Yes ,if he wants Multiattack he needs to get claws.
