I’m not totally certain how the catfolk weapon claw blades work and specifically how they interact with the Brawler class and the catfolk feat Claw Pounce. As I understand it, claw blades do two things:
1) Change a catfolks cat’s claws from a natural to a light slashing weapon.
2) Count as cat’s claws for feats such as Claw Pounce.
It’s not clear what weapon group claw blades belong to, though it would seem to make the most sense for them to be in the close weapons group.
If my understanding of how claw blades work is correct and if they are considered to be close weapons, then I think the following is a possible. A 10th level catfolk brawler wearing a set of claw blades could charge and then make a full attack with them. This could be a brawler’s flurry of four attacks whch can be done with close weapons at that level and one additional natural weapons secondary attack with the other paw that does not have claw blades on it.
Does this sound right, and if not, what am I missing.
Claw blades do not have a weapon group other than natural. So normally, the brawler is out of luck. However, there is another way to use brawler's flurry with a clawblade: the monk FCB.
Monk (Blood of the Beast pg. 4): Add 1/2 to the monk’s damage rolls with claw attacks and claw blades. A monk who selects this bonus at 1st level also treats claw blades as a monk weapon. If he is an unchained monk, he can use his style strikes with unarmed strike or claw blade attacks.
A brawler can flurry with a monk weapon. Of course it's just easier to do this with a straight level unchained monk. [Scaled Fist so you can use Cha for monk abilities]
Thanks for the rules clarifications and general advice. This is for a back-burner project that hopefully I'll get to play some day.
