I assume this is one the new JC items from GoD which you have to do the combines in AbSea to get axcess to.
for those who don't know that involves combining 5 different items 100 times and while handing indivually back to the vendor </Yawn> on the good side it is a free way to increase your skill to 70.
Hail the merch on left as you enter the room and say 'i am interested in helping with your work' she will give you a stack of items to combine in jewelry kit and just rince repeat for 500 combines.
*Remember one at a time folks <well 4 one in each handin slot>
