Download AbyssalCraft v.1.9.3.8 [1.11]

AbyssalCraft mod will give you the unique opportunity to visit the world of the dead (or in the abyss as it calls the author) - while remaining alive. Anyone who's played Dark Souls or Demon Souls, probably has a good understanding of how this concept works. You would be dead, but at the same time controlling your character.

actually, the mod has a total of three new dimensions. Players will start at the Deep Wastelands gradually descending the way down, travel through the Dreadlands and come in Omothol. In addition to the biomes mod adds of course new mobs, weapons, and various objects without which you cannot survive in the netherworld no matter how strange it may sound, because you would already be dead..
