o.k i buy the repair gem in item mall all it does is same repair as weapon merchant
how am i to make the endurance higher on items when its at 2 i though as alot of people though
you buy this gem and weapon item will go back to endurance like when it was made (WRONG)
ITS USLESS ITEM or is it bugged?

u cant  ==! this item make u repair without reduce endurance .

There is nothing wrong with the item. It can not repaire your maximum durability, but it will repair you weapon and make your maximum durability no drop.
