After installing this modification, you can find nuclear ore, which will be located underground in the normal world and space ore, which can only be found in the lower world.
After you have obtained a large amount of both ores, you can start crafting. In this modification, nuclear ingots can be made from nuclear ore. Space ore will simply be used in sword crafting recipes.
Once you have a nuclear sword, it can be enchanted and made the most powerful weapon in the game. Its damage will be around 1006 units, but in reality it is much more.
