WotC has declared the amulet of mighty fists overpriced, citing an alleged "uncustomary item slot."
Rules of the Game said:You can reasonably assume that a pair of gauntlets of mighty fists ought to have the same base cost and market price as the amulet (6,000 to 150,000 gp), depending on the enhancement bonus the item provides. The +1 version (6,000 gp) has a monetary cost to create of 3,000 gp (half the base price) and an experience cost of 240 XP (1/25th the base cost).
On the other hand, a +1 magic weapon (such as a +1 spiked gauntlet) costs only 2,000 gp (for the magical enhancement). Another quick look at the table on page 288 of the Dungeon Master's Guide shows that the amulet slot is best for items that involve protection and discernment, not attack, so it's a good bet that the amulet's price already had an adjustment for an uncustomary item slot. That makes sense, because almost any creature can wear an amulet or necklace and the amulet works on unarmed attacks and natural weaponry. The amulet of mighty fists probably also is intended for familiars and animal companions as well as monks.
That uncustomary item slot adjustment is x 1.5 (see Table 7-33), so the base cost and market price for the gauntlets would be 4,000 gp (6,000/1.5). The item should have the same caster level as a magic weapon with the same enhancement bonus (3 x the bonus), and it would require the Craft Wondrous item feat.
