Good news, I did a thing!
FTB Infinity Evolved Skyblock is now on the server but does not have “Expert mode” enabled yet. The pack is available via the FTB launcher and the Curse launcher.
Upon joining the server, you’ll see a stupid piece of computer with signs (because style). To start the game, simply type “/island join <your-name” as I’ve already created islands for just about everyone. If you have trouble joining try your name in all lowercase or bother me here/on Steam as I may have forgotten (eek).
More news is coming.
