Hello, May I suggest adding a Minigame plugin to the Skyblock server called "Mob arena". It is a plugin where you build different arenas and players can join, choose a class, and then try to survive an onslaught of different waves of mobs and Bosses. You can set it up to where each wave or how many concurrent waves can give out Rewards to the players for surviving. I have set up this plugin on 3 different servers and have made some very nice arenas for people to play on and people LOVED it! I have the config files if by chance you would like to see how I have set it up before and I would be more then happy to assist in creating the different arenas. I hope you will give "Mob Arena" a try!
