Animal Companion: Tricks and Purpose?

[Dracoknight]

I have two questions about animal companions:

Does the purpose you train them for count against their trick count?

Do every point in intelligence give 3 tricks, or is it just the first two?

Quote:

[I]f the creature is capable of learning additional tricks (above and beyond those included in its general purpose), it may do so.

I've never run into someone who doesn't run it as "general purposes count against tricks," and this text appears to confirm that. If purpose tricks did not count, then the parenthetical would be unnecessary.

To my knowledge there is nothing in the rules about tricks except at Intelligence 1 and 2. Beyond that, most players I know give their companions a rank in Linguistics so they can give commands, bypassing the trick system.

Every pt of INT allows for 3 tricks to be taught

Relevant excerpt
"...for every point of Intelligence it gains above 2, that is three more tricks it can learn."

A purpose is a set of tricks. Each trick in the set counts as a trick but the purpose itself does not

PRD

Relevant excerpt
"... an animal's purpose represents a preselected set of known tricks that fit into a common scheme"

The benefit of a purpose is that it requires a single training check (the DC is given in parentheses in the rules) and it can be used by a DM to adjudicate grey areas of what an animal might do that is not spelled out.

EDIT
Rules also state that if a package has more than three tricks, the animal needs INT 2+

Is that for all of Pathfinder or just PFS?

Specifically for PFS. But there's no reason it shouldn't hold true for regular Pathfinder as well. Really up to the GM.
