i wouln't even say that they need grapple/trip/etc related feats. i'd just saty that they need intuitive attack and combat expertise.
write it up in standard format too, cuz right now you have production commentary going on right in the feat description. other than that, looks good.
write this one in standard format too, and specify what kind of attacks they are. right now you mention claws and kicking, so it could confuse people that don't know kyrill's background.------------------------------------
For the Were-Bear Barbarian
Round-house claw to the face!
Feet of Fury (Fighter)
Requirements: Balance +10, BAB +10, at least one claw attack
At some point, you realized that the claws on your feet are just as sharp as those on your hands. Through extensive martial training, you have learned to strike with your feet as readily as with your weapon. While making a full attack with a weapon, you may also kick your opponent with your claw attacks.
A fighter may take this as her bonus feat.
Reasoning: There is a similar monk feat called "Lightning Fists", which allows you to take two extra attacks in a round, with all attacks made this round at a -5 penalty. I ignored the -5 penalty because both of Kyrill's claw attacks only deal two-thirds of the damage of a single fullblade attacks, so this is in fact much weaker than Haste or Lightning Fists and more about flavor.
For Kyrill the were-bear, this gives him:
Fullblade 1 / Fullblade 2 / Fullblade 3
Bite attack 1
Claw attack 1 / Claw attack 2
it should probably look something like:
Feet of Fury
At some point, you realized that the claws on your feet are just as sharp as those on your hands. Through extensive martial training, you have learned to strike with your feet as readily as with your weapon.
Prerequisites: Balance 6 ranks, +10 base attack bonus, one or more natural claw attacks, one or more limbs that are not normally listed as capable of claw attacks (four-legged bear that only gets two claw attacks)
Benefits: When making a full attack, you can make two extra claw attacks using your feet. All attacks this round suffer a -2 penalty to hit.
something like that.
