eq:Jewelcraft  

Jewelcraft is a tradeskill that allows players to craft items that enhance or augment existing armor and weapons. It can be quite costly and difficult to work on this tradeskill; it is not for the faint of heart, the impatient, or the adventurer of limited financial means. However, the items created often sell quite well to other players.
