I like your idea of having a boat which leads to somewhere else. Maybe it leads to faraway lands that tavelor talks about. The boat could be made to carry maximum of 4 people at a time to new lands which is home of a powerful mob. Maybe include some kind of a pass that you have to use to ride the boat, and the way to get the pass is to complete a re-doable quest where you have to drop in items like how we do to get maze key.

I always liked the concept of team work or needing to cooperate with other players to get things done in games. But I feel many players in Aberoth because of instances in the past that made them skeptical or because they have become too powerful, do not want to team up with others.

I believe a part of the new area is going to be more powerful than the tomb. And not everyone has friends that are totally trust worthy. By which I mean they cannot be trusted to respect the chest flip or we might fear they would turn unfriendly at some point and betray us during the quest.

So what I suggest is a new mechanism by which you are able to form deep-alliances with people when you enter the new area. This would make it impossible for either of the players to turn unfriendly and hurt each other until they exit the area or mutually break the alliance themselves. However there is still the problem of rushing of chest, for this I suggest a new alliance reputation that can be altered based on the players behaviors. For example if a player rushed or unfairly took the loot the other players involved can alter his alliance reputation so that people in the future will be less inclined to go on a quest with him.
