have list of all NPCs that are not locked by quests/areas/etc like all the npcs you vip tele to. randomize it. have each npc have the player go to the next random npc (which maybe anywhere in Vic Orbis leafre nlc Malaysia etc... until player has gone to every npc. reward exp + 100k NX bonus; same quest, fast travel and telerocks disabled, also taxicab disabled whenever possible to walk, much bigger reward going on with the same theme: visit random map, all maps on maple one at a time, tele rock fast travel disabled. (lightbulb quest )
How about instead we make the reward a 1 wa nx ring that lasts for 3 months, and then make it a yearly quest available during Xmas?
