It's nice that the Amulet of Mighty Fists can be enchanted with special abilities under the Beta, but they're still too cost prohibitive for monks. I propose a 3,000gp base price multiplier instead of the current 5,000gp one.
I'm playing a druid, and I'm not finding it too expensive, especially if you compare a +0 Holy amulet of mighty fists (20K gp) vs. a +1 Holy sword (18K gp), say.
Is it legal to take a +0 amulet of mighty fists? you are not allowed to take a +0 holy sword, so why can you get a holy amulet without the +1?
It specifically says so in the Pathfinder Beta rules. Whether that's a good idea or not is a separate question, of course.
The wording on it is wierd. It says:
but then adds:
, which isn't consistent with the first part.
I feel it should be consistent with other weapons and require +1 minimum.
Honestly, since this applies to two OR MORE "weapons", it doesn't seem too expensive, compared to a 2-Weapon-Fighter who needs to buy (and upgrade) two separate weapons: The Fists are only 25% more expensive than 2WF (NOT counting base weapon costs), and apply to all Unarmed/Natural Attacks, which means outpacing a 2WF (in # of attacks) is easily possible.
If Enhancement bonuses apply to Maneuvers (which is uncertain, but a possibility, certainly if Maneuver AC is adopted), then Unarmed being able to attempt ALL Maneuvers with this Enhancement is certainly a signifigant benefit. I simply don't see the pricing as problematic: Any extra cost is countered by the benefit of concentrating on one "weapon", which scales well with level.
All in all, this seems a very effective item for both Monks and "Bad Asses with Multi-Attack".
