Rotting Away
Rotting Away is a Fabric mob mod in which an undead death spreads infection, and a Silver metal line gives players a counter to it.
What it does
Infection starts with a single undead death. Undeads that die leave a rotten mass behind, and a mob that walks over that mass begins to zombify. Once enough mass has built up near undeads, they can turn into an Abomination, a very hostile mob that attacks non-undead creatures. An Abomination explodes exactly one day after it spawns and leaves rotten mites behind, which spread into uninfected land and turn nearby blocks into rotten mass. The mod also tracks a number-based power that grows as a mob claims more ground.
Silver is the counter to the spread. Raw Silver comes from mining Silver Ore, is smelted into Silver Ingots in a blast furnace, and nine ingots craft into a Silver Block. Placing a Silver Block above a copper grate and a lava cauldron melts the silver into Molten Silver, which a bucket can collect. Molten Silver poured over rotten mass decays it. Smiting swords deal extra damage to undeads.
Rotting Away needs Fabric API. Installation covers the server and each player's game. Files are published for Fabric only, for Minecraft 1.21.1, under All rights reserved, and the code is not open source.
Key features
Undead infection
A single undead death can seed an infection that spreads through rotten mass across the land.
Abomination mobs
Enough accumulated mass lets nearby undeads turn into Abominations that attack non-undead mobs.
Silver smelting chain
Silver Ore, raw silver, ingots and blocks form a path from mining to a usable metal for the counter.
Molten Silver decay
Molten Silver poured onto rotten mass decays it, using a bucket collected from a lava cauldron setup.
Smiting swords
Swords in this set deal extra damage to undeads, in addition to the normal damage that other mobs take from fire.

How it compares
Custom Weapons is a Fabric mod for 1.21 – 26.2 that is also client and server, under All rights reserved and not open source, so it adds weapons rather than an infection system. Silver & Withers is a Fabric mod for 1.21.11 with the same environment and license, and it only covers that one version. Polymer Patch for The Silver Age is server-side only and open source under the MIT License, for 1.21.8, so players do not install it. Rotting Away targets 1.21.1 alone.

What the author says
Infection mods these days like to copy each other. If you are getting bored of this trend, this unique twist on infection mods is a must-try, overhauling zombification and undeads. All of this infection begins with 1 undead death. When Undeads die, they leave behind rotten mass.
