How do I install Unbreakable Spawner?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

What Minecraft version does Unbreakable Spawner work with?

The listing gives Minecraft 1.21.1, 1.20.1, 1.19.2, among others. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Makes mob spawners unbreakable.

You cannot mine them.

Thats it.

Uses blockHardness = -1 as well as some data tags

I love this change in my worlds since it makes dungeons more Real and challenging, makes you build around them, or light them up or build a farm. cant just remove any blaze spawner you want etc, its there forever. Works regardless of what mob is inside.

Unbreakable mob spawners — regular monster spawners can no longer be mined or destroyed with any tool, same hardness as bedrock.
spawner block added to block/dragon_immune.json
Zero setup — no new items, blocks, or recipes.
Client + server — works the same in singleplayer and on dedicated servers.

(You probably wont need this if you are making modpacks with things like crafttweaker and zenscript, they usually have built in support for block hardness)
