Crafting Amulets is a good way to level up crafting skill. But what does one then do with 30 Amulets of Attack? There really doesn't seem to be much of a secondary market for them at this time.
One possibility would be the ability to take say, 10 Amulets of Attack + some amount of energy, and create an Amulet of Greater Attack that would give the user greater benefits than the regular amulets.
This would also please the Lindens, as my inventory already creates a massive server load, and less amulets = less inventory! ^.^
