I would say yes. But that's also a lot of feats to get too specially if not a monk.
6 total plus ranks in bluff.
If talking about your character:
You got Improved Unarmed Strike. Need to pick another feat (Your still level 3), so thats 2. So your looking at level 18.
6th 1 feat, 9th 1 feat, 12th 1 feat, 15 1 feat, 18 then can take it.
If your a monk you can probably get it sooner or possibly a fighter.
