Sleepo's Slime & Progression
Sleepo's Slime & Progression is a Fabric server mod that adds slime-based items and a progression ladder built around iron.
What it does
Slime items in this mod can be eaten endlessly, which is the mod's most unusual behavior. Iron is split into smaller pieces: a dirt iron fractal, an iron fractal and an iron nugget form a chain of ever-finer iron items. The author describes the mod as aimed at making Minecraft somewhat cooler, and as a way to annoy friends in multiplayer.
The author plans a larger update that would make items require extreme progression to obtain. No such update is included in the 1.0.0 release, so the current content is limited to the slime and iron items described above. The mod is built for Fabric and covers five game versions, 1.20 – 1.20.4, with 1.0.0 for 1.20.4 as the latest file, published on 2024-03-12 and released under the MIT License. It is not open source.
Only the server needs the mod: players join without installing it, so the server owner is the one who adds it to a Fabric server. The mod lists no required dependencies on its page.
Key features
Infinitely edible slime
Slime items can be eaten repeatedly, a joke-driven mechanic that sets the mod apart from ordinary food.
Iron fractal chain
Iron is split into smaller pieces, from a dirt iron fractal through an iron fractal to an iron nugget.
Planned progression update
The author says a future update will make some items require extreme progression, but this release does not add it.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Who it’s for: Server owners and players who want playful, unserious additions to a Fabric server. The mod suits joke-driven play more than balanced progression, as the author's own notes suggest.
