Break Me Down (BMD) allows you to craft some blocks into their ingredients allowing you to revert some craftings. For example nether wart block -> 9 nether warts.
Looking for something that will work on vanilla minecraft or non-modded server? Check out the Datapack Version!
This mod adds 19 new recipes that allow you to break blocks into their ingredients.

This mod comes with 13 new advancements that will help you discover new recipes and give you some experience points once achieved.

Mod supports following languages:
English

I plan on updating this mod once new full releases of Minecraft comes out.
If you want some extra compatibility for blocks or items introduced with orther mods, let me know on Discord and I will release additional add-ons giving compatibility with desired projects!
