I do not know if it is possible to modify pserver to have dungeon 125. My first plan is to have dungeon 125 similiar to dungeon 115. So I will modify the QuestDungeon.scp by copy the line for dungeon 115 to another line.
The original line for dungeon 115 is
294 0:11 0 0 6 115 7 3000 1 1185:1313 1693: 10000 294 0:0:0:0:0:3000:0 4 236 241 241 236 23 0 1 3 115 1 2 0 0 0 1
??? 0:12 0 0 6 125 7 3000 1 ????:???? 1693: 10000 294 0:0:0:0:0:3000:0 4 236 241 241 236 23 0 1 3 115 1 2 0 0 0 1
Another file to modify is world8-npc.scp
[WarpLst] NpcsIdx NSetIdx TargetIdx LV Fee Type
0 1 0 28 1 0 0
1 8 0 273 95 0 1
2 10 0 294 115 0 2
3 10 0 ??? 125 0 2
4 11 0 28 1 0 0
5 12 0 28 1 0 0
The 294 is warp number, 1185:1313 is Muster Card B1F. So I need to find the warp number (may be 297 or more) and the item code for Muster Card B2F. Is is possible to find these values from the original client?
