Arthritis
by ProstStuff
Arthritis is a NeoForge challenge mod for 1.21.1 that adds bleeding and fracture mechanics, along with other nuisances meant to make survival harder.
What it does
Arthritis is aimed at players who find Minecraft too simple and want the game's progression to carry a few challenges. Its new mechanics include bleeding and fractures that players can inflict on themselves, and the mod changes existing rules, for example by making most wood-related recipes unavailable through normal crafting. Players spawn with a pebble inventory, and time, weather and biomes are affected as well.
Crafting moves toward a more primitive path. Flint can be crafted from three Flint Shards and a Flint, and Drying Net, Dried Fiber and a flint-based tool set are added. Chopping and drying recipes run through the new systems, and the mod adds a lighter axe and tools in several materials, from flint up to netherite. Dried fiber is obtainable through a Drying Net, and string can be made from it.
The mod is a NeoForge build for 1.21.1 only, released under All rights reserved and not open source. Servers that run it need every player to install it too. Its latest file is 0.0.9-alpha, published on 2025-05-16 on the alpha channel, and the first release dates from 2025-04-22. A later update was put on hold by the author.
Key features
Bleeding and fractures
Bleed and Fracture are new status effects that players can inflict, adding a risk to combat and falls.
Drying and chopping recipes
Drying Net and chopping recipes handle flint and wood processing in place of ordinary crafting.
Flint tool tier
Flint tools form a tier between the vanilla materials, and an axe strips blocks faster than the standard one.

What the author says
After "careful" consideration, 0.1.0-beta or above is put on hold/delayed and there will be no planned update schedule. Due to certain circumstances, I am sorry. I can't extend the idea furthermore or a will to continue. As this mod is used for me to learn Java, and as a beginner, it's hard to manage those spaghetti…
