Entropic Block Magic

Exchange blocks can put slabs back together, turn stairs back into the full blocks they came from, and reverse decorative steps such as unpolish, unbrick, unwall and untile. Spells cast from a wand can extend structures in the manner of a builders wand, replace ground blocks with ones held in the offhand, and throw raw cobblestone, ore and other items from the inventory onto the ground in front of the player. A search feature scans chests within a 10 block radius for requested items.

The mod is tied to location through a world entropy value that ranges from -350 to 350, and some spells need the entropy to sit within a specific band, such as 100. Spells can be looted and have alternative casting costs, and a book crafted with a quill, a diamond and a prismarine shard holds the player's favourite entries. Most utilities look up items through registries rather than hardcoded lists, so blocks added by other mods that follow standard naming are usually handled without extra setup.

The mod runs on Fabric and is published for six release versions, 1.20.1 – 1.20.6. It is released under the MIT License and is open source. Both the source code and the issue tracker are public. Client and server share it, so the server and every player install it.
