So I've seen this only one one other server and i remember only wanting to play that server Simply for the fact of the Dungeons and giving players another way of making money and interacting with the server, Have the Community Share there own builds, being the dungeons of any difficulty from easy to Extreme, what ever u may want to call them and have this plugin 'TreasureChest' Have the items rewards at the end of that dungeon, it maybe a little bit of work with command blocks for say if u touch a certain block you get teleported back to the start, For instance Piano Tiles the game on your mobile, or having something just ranging from Mob Fights to mazes to Puzzles or Park-our, The Opportunity's that could come of this plugin would be nice and I'm sure the community may like it or may not Thanks for Reading - Cydea https://dev.bukkit.org/projects/treasurechest
