Animal focus question

[Orcsmasher]

This ability allows the Hunter to take on the aspect of animal.
What exactly is an aspect?
Is it like shapechange or wild shape or is it taking on the abilities of an animal?

It is exactly as listed: it is not a polymorph effect, and it grants you a bonus, typically to a stat or skill. It grants only the abilities listed under the various Animal Focus types (eg. for Bear, you gain a +2 enhancement bonus to Constitution, increasing to a +4 bonus at level 8 and a +6 bonus at level 15).

Reading the text of the Animal Focus ability is all you need: it is fairly unambiguous and specific as to the benefits you gain.
