Stuff Ain't Cheap
Villagers in vanilla Minecraft have a dirty little secret: they pull diamond gear out of thin air. Hand an Armorer a stack of emeralds and a few pieces of coal, and suddenly you are walking away with a full diamond chestplate. Stuff Ain't Cheap puts a stop to that nonsense. This add-on reworks villager trading so that diamond equipment actually costs diamonds, while keeping the prices below what you would spend crafting the same gear yourself.
What Stuff Ain't Cheap Changes
The core idea is simple economics: if a villager is selling diamond gear, they should want diamonds in return. The add-on applies this logic across several professions, and the result is a trading economy that feels earned rather than exploited.
- Armorer, Toolsmith and Weaponsmith villagers now request diamonds as part of their payment for diamond equipment, though the total cost still undercuts crafting from scratch.
- Librarian first trade pool no longer contains Enchanted Books, so you cannot reroll a fresh librarian for a cheap Mending book on day one.
- Librarians now ask for Diamonds instead of a single book when selling Enchanted Books.
- Low level Enchantments are gone from librarian offers entirely, and the quality of enchantments scales upward as the librarian levels.
If you have ever built a trading hall and watched it print diamond gear like a factory, this mod is aimed squarely at you. It does not remove villager trading, and it does not make the grind miserable. It simply closes the loophole where emeralds alone could buy you endgame equipment.
Supported Versions and Loaders
Stuff Ain't Cheap for Minecraft targets modern Java Edition releases, and the version you pick determines which mod loader you need.
Version 1.21.1 to 1.21.5
These builds run on NeoForge 21.0.0 or superior. If you are already on a NeoForge 1.21.x profile, dropping the mod into your mods folder is all it takes.
Version 1.20.1
The 1.20.1 release requires Forge 1.20.1 - 47.1.43. This is the version most modpack players still live on, so expect it to be the most widely used build.
Version 1.19.2 and Above
For older worlds, the 1.19.2 build (or superior) runs on Forge 1.19.2 (or superior) - 43.2.21. Compatibility here means you can retrofit the add-on into an existing 1.19.2 save without regenerating anything.
One practical note: if you are juggling multiple modpacks across different loaders, the foxygame.net launcher keeps Stuff Ain't Cheap matched to the correct NeoForge or Forge build automatically, so you are not hunting down the right jar for each profile by hand.
How to Install Stuff Ain't Cheap
Installation follows the standard add-on routine, and it takes about two minutes.
- Confirm your Minecraft version and install the matching loader: NeoForge 21.0.0 or superior for 1.21.x, Forge 47.1.43 for 1.20.1, or Forge 43.2.21 for 1.19.2 and above.
- Download Stuff Ain't Cheap from the official project page and place the jar file into your mods folder.
- Launch the game once with the loader active so the mod can register its trade tables.
- Load an existing world or start a new one. Villager trades update on their own, though villagers you have already locked into a trade keep their current offers.
If you want to download Stuff Ain't Cheap and test it immediately, back up your world first. Trade table changes are safe, but it is good practice before adding any mod to a long-running save.
Who Should Use This Add-On
Players who enjoy the early and mid game will get the most out of it. The mod restores a sense of progression because diamond gear stops being a shopping trip and starts being an investment. Server owners benefit too, since trading halls become less of an infinite resource and more of a legitimate business.
Players who prefer pure vanilla convenience may find the librarian changes annoying, especially the loss of cheap Enchanted Books. That is a fair trade-off, and it is the entire point of the design.
Final Thoughts
Stuff Ain't Cheap is a small, focused add-on with a clear philosophy: rare materials should cost rare materials. By making villagers charge diamonds for diamond gear and tightening librarian enchantment offers, it rebalances one of the most exploitable systems in the game without breaking it. Whether you run it on NeoForge 1.21.x or stick with Forge 1.20.1, the result is a trading economy that finally makes sense.
