DO NOT WORK ANYWHERE, retail/privat server !!!
Why ? Check in C4 data base Where is mobs like "treasure box" and Treasure Chest" witch originally have same title TREASURE CHEST, was esy to "fix" changing npcname-e.bat.
THIS WAY DONT WORK ON INTERLUDE,CT1 or HELLBOUND, dont know how about c5.
P.S. Duno you must be playing in c4 privat server
Yes i play in privat server, this way worked then it was C4, more, server uses retail global server files now (as it updated hellbound), only rates are changed, no mod and other **** (patch is only lounher to conncet) it is not l2j and whis way don't work. !!!
