Welcome to Cosmic Armory, this mod adds some great new passive machines as well as a new crafting system. The end goal of this mod is to add weapons and armor in a way that doesn't feel like just another mo'swords mod.
One: Craft a Solar Dust Collector, this will put you on the path to Comet Tools, fast but not super strong. Once crafted, place the machine anywhere and wait, it's as simple as that. It will collect a couple resources for you on the side, but what you're looking for is Comet Tail Dust.
Two: Craft a Bedrock Miner, this will put you on the path to Dense Steel Tools, super heavy duty. Once crafted, place on bedrock and wait, once again it's that easy!
Three: Find a meteorite. Sounds hard, but it's not. Once found, they must be mined with a diamond pickaxe or higher.
Step Two: Make a Cosmic Forge, smelt any of the three resulted items with iron ingots to get better ingots. This forge will eat up anything blue and shiny instead of coal!
Step Three: Make the tools and armor like you would with vanilla tools.
Going Further: To gain creative flight in survival, you must craft the shells of each armor piece, made with a Dense Steel armor piece and the respective meteorite ingots in the shape of that piece around it. Then smelt this with a comet armor piece of the same type. It sounds like a lot because it is, but this will result in super strong armor with creative flight!
