This world is meant for the Odds and Ends modpack, please don't download without the mods because the world will break.
This world is like the original 1.7 or 8 skyblock, but with added mods and updates to allow the player access to things like netherite and the Ender Dragon, which you need to defeat to "finish" the map. You can continue to play in the world after the dragon is defeated, however.
This world is multiplayer compatible, but harder to finish without the modpack. Have fun trying to fight the dragon!
