Anchoring unarmed strike....how would this work?

[FiddlersGreen]

Anchoring:

This special ability can only be added to a melee weapon or a
thrown weapon. An anchoring weapon pins a target in place
and prevents it from moving. As a swift action, the weapon
can be fixed in place in a point in space, functioning as an
immovable rod. This ability can also be used when the wielder
hits a creature with a melee attack using an anchoring weapon.
This anchors the target to the weapon, preventing it from
moving away from the weapon. The target is not entangled or
paralyzed; it simply cannot move from its location without first
destroying the weapon or making a successful DC 30 Strength
check as a full-round action to move with the weapon up to 10 feet.

An anchoring weapon remains motionless and cannot be
used to attack while it is anchoring a creature. An anchoring
weapon has no effect on amorphous creatures, including
elementals, oozes, and creatures in gaseous or liquid form. It
also cannot anchor incorporeal creatures unless the weapon
also has the ghost touch special ability.

How would this item work for my PFS monk?

1. Can I put the property on a bodywrap of mighty strikes?

2. If I do and trigger the ability, does it achieve anything since the bodywrap only affects my unarmed strike for the duration of the attack(s).

3. If it does work, is is just the body part that I used for the unarmed strike that is immobilised, or is it my entire body?

4. On a different note, does the line "This enhancement can only be placed on a melee weapon which is usable with the Weapon Finesse feat." prevent the agile weapon property from being put on an amulet of mighty fists?

I think you would grab them.

i think you are better off putting this on an amulet of mighty fist. having all of your body parts count as an immovable rod, as a monk, all the time.

but i dont think using it for an unarmed attack would change anything about how it works. if you use the effect on a strike, the body part used would be anchored in space just as any weapon would have been. you are not stuck just what you struck the target with, so dont use it with a frog splash.
