So suppose I make a ninja, and choose a race that can give me a couple claw attacks - Catfolk, Tiefling, or Tengu, for example. Now take the Adopted trait for the Half-Orc Tusked race trait to get a bite attack (or use the bite attack that comes for free with the Tengu).
At level 1: Take the Multiattack feat.
At level 2: Take the Unarmed Combat Training ninja trick to gain Improved Unarmed Strike as a bonus feat.
At level 3: Take the Two-Weapon Fighting feat.
Now my reading of Improved Unarmed Strike is that you can use it for kicks. So does this mean I now have 5 attacks: Claw, claw, bite, kick, kick?
And unarmed strikes count as light, so they're only at -2 each thanks to Two-Weapon Fighting. Using the unarmed strikes with the natural attacks makes all the natural attacks count as secondary, but thanks to Multiattack they're still only at -2. And if I'm flanking or the opponent is denied their DEX bonus to AC via being blinded or stunned or whatever, do I get my 2d6 sneak attack bonus damage on each attack?
Furthermore, when I get to level 8, my BAB hits +6, so do I get *another* attack with my foot that can get sneak attack damage (now at +4d6)? And yet another if I take Improved Two Weapon Fighting? (If so, I'll probably be taking Improved Two Weapon Feint shortly thereafter).
I know this might not be the best way to do this build (ninjas probably want Weapon Finesse pretty early), but do the rules work the way I've described?
