Alternatively, this amulet can grant melee weapon special abilities, so long as they can be applied to unarmed attacks. See Table: Melee Weapon Special Abilities for a list of abilities. Special abilities count as additional bonuses for determining the market value of the item, but do not modify attack or damage bonuses. An amulet of mighty fists cannot have a modified bonus (enhancement bonus plus special ability bonus equivalents) higher than +5. An amulet of mighty fists does not need to have a +1 enhancement bonus to grant a melee weapon special ability.

Does the amulet of mighty fists allow a creature’s natural attacks to bypass damage reduction if the enhancement bonus is high enough?
Yes. If the amulet grants at least a +3 enhancement bonus it allows a creature’s natural attacks to bypass cold iron and silver damage reduction. If it is +4, it allows them to bypass adamantine damage reduction (although not hardness), and if it is +5, it allows them to bypass alignment-based damage reduction.
If a creature with multiple natural attacks (such as bite/claw/claw) wears an Amulet of Mighty Fists with the speed property, does it get one extra attack with each of its natural weapons?
No… mainly because that combination is way too good for monsters with multiple attacks, and gets better the more natural attacks a monster has. Doubling a creature’s attacks per round is really powerful, even for 80,000 gp (the price of a +4 amulet).
The Amulet of Mighty Fists’ price and cost were updated in a recent Paizo blog. This page reflects those changes.
