This is a massive pack used for the BOI private server, containing 325+ mods, and to be possibly updated with more in the future or to fit the pack better.
These mods range from massive tech mods, where you can build a fully automated foundry and never have to mine again (From buildcraft quarries to void drills), or magic mods, where you can craft spells to toy with your friends or enemies(From thaumcraft to astral sorcery). Or even go to space and nuke moon villages. The world is your playground, then again when isn't it.
This pack was designed with long multiplayer play in mind, allowing players to chose their own path and start their own adventure into this pack. And with no quest book the world is an open door for you to find out.
