So I'm creating a Cavalier with a Griffon Mount.
As per Monstrous Mount at lvl 7 it gains Pounce, which it can use with a Bite and two Talon attacks.
As per Mounted Combat rules: If your mount charges, you also take the AC penalty associated with a charge. If you make an attack at the end of the charge, you receive the bonus gained from the charge.
So following those rules: Your mount actually carriies our YOUR Charge action and you simply gain the benefit.
So if my Mount takes a charge action she should be able to pounce with it. And since it's part of mounted combat i can also take my attack at the end of the charge.
Things get complicated when you consider Ride-by Attack
The feat states that "you may move and attack as if with a standard charge and then move again". Does this mean that my mount can Charge an enemy, make it's full-pounce attack, then keep moving the rest of the movement.
Ignoring Charge-paths adn the PCs attacks.
I've already speculated a bit on this and i'm interested if there's any rules/erratas/official statements towards this that can help clarify this.
