Help me understand how this Grappler I made works.

[Mako Senako]

This weekend, i will be returning to a old game with a 11th level character. I went through all the allowed material and created a guy who is to serve as the party Tank/Healer

I took a human took, 4 levels of Oracle, 1 of Warlord, 6 Battle Templar.

Relevant Feats,
9th-Fang & Fury, 11th-Mighty Frame,

Relevant Stance,
Primal Warrior Stance

Okay Mighty Frame basically gives me the Powerful Build racial trait,
and Fang and Fury basically says once per round whenever I activate a strike I can make a free bite attack.

However I have the Oracle Curse Hunger, which basically gives me a bite attack, and at 5th and 10th level it increases in damage as if I was one size larger, and I can automatically initiate a grapple when the bite hits someone 1 size smaller than myself.

So This is what I want to clarify.

Primal Warrior Stance Warrior stance also gives you a version of Powerful build, but it's supercharged. The difference is that in Primal Warrior Stance your weapon damage (manufactured and natural) work as if they were 2 size categories bigger, and you for all advantages purposes count as if you were one size larger, the kicker is that it says "The benefits of this stance stack with abilities or effects that increase the initiator’s size (such as enlarge person).
And Mighty Frame says, "`The benefits of this ability stack with the effects of abilities, powers, and spells that change the subject’s size category."

So now when I switch to Primal Warrior Stance and walk over to Mr Big Bad, and chop him with my axe do I hit him for 6d6 damage, then bite him for 3d6 damage, then automatically initiate a grapple because of the Grab special ability?

Is my grapple modifier going to be as if im a huge creature? (mighty frame + warrior primal stance)?

So if I'm considered huge then my Grab should work on creatures Larger and smaller correcT?

How many arms do I need to maintain a proper grapple on the target?
I'm assuming my mouth isn't enough.

You would only be considered Large not Huge as they are both effective size increases which only stack with actual size increases (Such as enlarge person, righteous might and other effects that increase your actual not effective size)

You would still need both hands free to grapple normally unless you are going to use the special grapple action from Grab called Hold.
Hold says you suffer a -20 to your grapple check but if you succeed you do not gain the grappled condition and can move freely.

Otherwise, Grab adds a +4 to a grapple check, but you take a -4 penalty on grapple checks when you don't have 2 hands free...

I'd think the limb with the Grab Ability + 1 hand removed from the Axe should count as 2 hands.

I'd say your mouth in this case counts as 1 hand.

But if the GM nixes that, letting go of the axe is a Free Action.
