A mix from the Mods: Hekxit und tekkit.
It's a modpack with a wide variaty of different kinds of ores, mobs and dungeons. (e.g. diamonds can be found at earth ground.
This modpack's focus is in technology and in withcraft. So you can either decide to either rely on an (very small in number but large in space) storehouse.
Or you can construct your own weapons (not only consisting of wood, stone, iron, gold and diamonds).in other words Tinkers Construct.
You can also do some magic crafts, through wich you can get buffs from time to time.
After you played this modpack, you will have a different kind of view of minecraft.
Have fun
