This mod is intended to be used with "Cracker's Wither Storm" mod. It simply allows you to craft from various components and place down command blocks in survival. You can mine them once they are placed down but they don't drop anything (I can't add a loot table. I tried), and but you cannot use them once they are placed down unless you are in creative.
Each of the components can be found in the following structures:
Command Chunks can be found in Desert/Jungle Pyramids! (10% chance)
Command Panels can be found in Bastion Remnants! (7% chance)
Command Cores can be found in End Cities! (5% chance)
I'm done with Forge modding altogether, all mods that have a Fabric version will continue to be supported. I cannot guarantee the future of this mod.
