Hello, i want to propose something I saw in Wom2 back when i still played it. It had a feature that there were droppable Treasure maps with a level limit. Using this item shows you a place of a corresponding map with an X that marks where the room is. It could be party-only accessible challenge, where you have to fight for the Treasure with a random boss monster, corresponding to the level of the Treasure map with a 5 minute time limit to kill the boss. All party members get separate rewards if they emerge victorious.
I think that would improve the team work of the guilds/friends on the server whilst bringing rewards to the players, and kinda bring some life to farming, instead of mindlessly grinding metins all day.
EDIT : When the treasure map owner and his party arrive at the location, the party owner MUST click on the Treasure map item in their inventory. Then the players in the party (party is mandatory, I repeat!) get teleported in a secluded room to fight the boss. Once the boss is down, a Treasure Chest will spawn. Players have to click on it to get AND get their loot separately. After 60 seconds have passed, the party automatically is teleported to the map they used to enter the room, regardless if they claimed their loot or not.
The boss for every level is random, and map corresponding, e.g. - Temple boss can be either Dark Leader or Yellow Tiger Ghost, at level 60/70, depending on the Treasure Map level cap.
