Quest: Amber Kaming Transaction

Go to East exit of Explore Map through that narrow bridge, you'll arrive in Kaming Camp. Then find a tent at X: 040 Y: 020. (not far from the entrance)

Talk to the man inside, he'll help you summon a spirit into Fire Sword. But first you need to bring him some (a lot) items and Coins.

Once you bring all the item he need, talk to him again. He'll trade the items for Spirit Fire Sword, Tobacco Pipe and Legend. But remember that you'll lose some Karma after doing this quest.
