KleeSlabs (Outdated Versions)
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.
This project has been moved. Click here for Minecraft 1.21.2+ versions.
This mod allows you to break only one half of a double slab. The half that is broken depends on which half you're looking at.
It supports Vanilla slabs as well as many modded slabs. Modded slabs that do not work yet should be reported on the Issue Tracker.
This mod is available for NeoForge, Fabric and Forge. It requires Balm, which must be installed alongside the mod.
- Break only the half of a double slab that you're looking at
- Supports all Vanilla slabs
- Supports slabs from many different mods
This mod was made by suggestion of Kleetho during one of her Subathons, hence the name.
