Not to necro the thread once more, but it is on top of google for Nimble Guardian.
There is a serious issue with how the original author calculated the damage for the attacks.
Claws are natural weapons, and unarmed strikes are considered manufactured weapons. Feral combat training lets you use claws in a flurry of blows, and apply monk feats to them, but it does not suddenly give you six full STR iteratives at level 9.
When you use natural weapons in a full round, you either use them as primary ( without any "manufactured weapon" attacks in the full-round) or as secondary attacks in addition to your "manufactured weapon" attacks.
If you use them as secondaries, in addition to the-5 BAB penalty, they only do HALF STRENGTH bonus on damage, which cancels out the Criosphinx double STR bonus.
You also can't actually take Multi-Attack without having three natural weapons to begin with (which a human, even with Catfolk Exemplar, does not, she only has the two claws, you'd need another source for the third).
Additionally, he somewhat misleadingly writes the Rake attacks out in the block with the iteratives. Dire Tigers only get the 3rd and 4th claw attacks as part of a Rake, which can only be done on a target they began the round grappling, and cannot be done in the same round the target is grappled.
Therefore, at level 9 for this build, the attack calculation for a full pounce should be
Unarmed Strike (4d8+16)
Unarmed Strike (4d8+16)
Bite (2d6+8)
Claw (4d4+8)
Claw (4d4+8)
Which is still a lot of damage, but is 8d4 + 48 damage LESS than the original calculations.
As an aside, Warcat of Rull from the Belkzen Hold books would be a better cat choice. It's naturally huge, with 15' reach, and has both Rend and Trample instead of Rake, which adds more damage upfront.
