also, reposting the combat section for comment:
COMBAT
A rakasta fights fiercely, expecting its opponent to do the same. Though rakasta can use normal weapons, they disdain such equipment and prefer to rely on their own natural weapons. Rakasta are often armed with a special set of metal war claws that they call kasas, which are worn on the paw like a glove.
Rakasta that ride saber-toothed tigers use special saddles that enable them to fight unhindered while mounted. These saddles allows them maintain control of their mount by controlling the tigers with knee pressure, and do not hinder the mount’s combat capabilities. These saddles also allow them to leap and attack in the same round.
Improved Grab (Ex): To use this ability, a rakasta must hit either with both claw attacks or both kasa attacks. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can make two rake attacks with its rear claws.
Rake (Ex): Attack bonus +X melee, damage 1d3+1.
Mounted Leap (Ex): A rakasta can leap up to 20 feet from its mount and still make its full attack in the same round.
and when that is settled, i'll need to work up a "rakasta as characters" bit.
