I'm reluctant to drag up this old topic, but as much as I've searched the forums, I am unable to find anything official by the developers on this...unless the official response is enjoying a Concealment effect against my Search attacks.
I understand the difference between Unarmed Striking and Grappling. They are differentiated in the Weapon Focus Feat and as such it makes sense that WF (Unarmed Strike) does not translate into a bonus on Grapple checks and vice versa. Even though they both employ free hands, they are two different styles of combat. Got that.
The lingering question, and I know there have been a plethora of legitimate and well-reasoned responses on both sides of this, is:
Does having magically enhanced gauntlets and/or the Mighty Fists Amulet grant a bonus to Grapple CMB?
The implication at first glance would seem to be 'yes'. Since grappling requires you to have both hands free to avoid a penalty, then the hands are being used. However, as stated above, using hands that grab as opposed to fists that strike are two different combat modes. But then so are striking with a sword and using that sword to Trip (and yet the bonuses translate over from one fighting technique to another).
As mentioned, I have read all sorts of replies and reasoning on this topic, but I am curious as to any "official" ruling on this matter other than "delegated to DM ruling".
So if anyone can elaborate on this, I would be most thankful.
