New Dimensions:
This mod adds 3 new dimensions each with their own characteristics, biomes, and minerals. There is one in particular where you will get a specific mineral to craft mystical artifacts, and then it is purely exploration.
New mobs:
There are new flying mobs for each dimension, and we added new bosses that can only be summoned with structures.
New Biomes:
Apart from the new dimensions, biomes were added to the nether with new mobs and blocks.
New minerals:
Platinum and sapphire are those that stand out in new minerals, since these will be essential to create artifacts and new armor. You can find both in the overworld
New Weapons:
The katanas were added with this mod, and what the mechanics of the katanas consist of is being able to complement them with artifacts or precious stones, and bringing more of the mechanics of 1.8 with indefinite speeds of these weapons.
