Pounce (Ex): If a sphinx leaps upon a foe during the first round of combat, it can make a full attack even if it has already taken a move action.

Rake (Ex): A sphinx that pounces onto a creature can make two rake attacks with its hind legs. Attack bonus +15 melee, damage 1d6+3.

Most sphinxes fight on the ground, using their wings to help them leap much as lions do. If outnumbered by earthbound creatures, a sphinx takes wing and attacks on the fly.

Criosphinxes attack with their claws and deadly bite, as do their kin, but they can also butt with their horns. They don't cast spells and employ only the most simple battle tactics.
