How to Build Cruxes for Nether Star, Neutronium, and Nitro Crystal
What a Crux Is
Cruxes are placeable blocks that gate the mod's top-tier materials. The registry includes Awakened Draconium Crux, Dragon Egg Crux, Gaia Spirit Crux, Nether Star Crux, Neutronium Crux, and Nitro Crystal Crux. Each crux is tied to a specific material line, so build the one that matches the material you are chasing.
Nether Star Crux and Nether Star Shard
Nether Star Crux is the block you place for the Nether Star line. Nether Star Shard is the item that goes with it. Place the crux, supply the inputs its tier needs, and collect the shards. This is the line to run if you want Nether Star material without hunting the vanilla boss.
Neutronium Crux and Nitro Crystal Crux
Neutronium Crux and Nitro Crystal Crux are the other two high-tier crux blocks. They follow the same pattern: place the block, feed it, and take the output. Build them near your storage so you can restock inputs quickly.
Awakening
This mod includes an mysticalagriculture:awakening recipe type. That is the process that pushes a crux line to its awakened form, and Awakened Draconium Crux and Molten Awakened Supremium are the endgame results. Set up your crux blocks first, then run the awakening step once you have the inputs gathered.
