I'm got a Feral Champion Warpriest and I just realized that even with 4 natural attacks at level 2 (Kistune and a single level of Adaptive Shifter), with possibly 3 more later from some items, it doesn't matter too much since moving means only being able to use one at a time.
So I was wondering how I would get pounce on my build? There's Vulpine Pounce but you can't get it until BAB 10, which for a WarpriestX/Shifter1 is level 12. And the Greater Beast Totem rage power requires 10 levels of Barbarian which I don't want to do.
Are there any other ways?
The Tail Slap from your shifter level would still be a secondary attack, no? Not a very attractive dip.
Would probably be better to check out the Alternate Natural Attacks table and see what Aspects have uncommon alternate attacks. Talons, Stings and Pincers are Primary attacks available to you.
As for the pounce option, Vulpine Pounce seems like the easiest and cheapest option available. Doesn't mesh well with a Warpriest though, since you'll want to use your swift actions for Fervor.
