this bug works since january 2007
The idea is to reuse the Lunargent and the HellFire Oil..
1.-Have mixed the materials 5Lunargernt and 1 HellFire.
2.-Make the quest even they request this mats.
3.-Talk with Noel " I cant Help?..." <--click it.
4.-When you see " Listen " Don't click it.
5.-Trade the mats to some friend, drop it on the ground or deposit it in warehouse.
6.-Press " Listen " and you got it.
7.-You have still the mats and u are able to get nobless many times as u want.
sorry for my english...
i will be glad to answer ur questions.
