The Silence Infection
by Arcane5050
The Silence Infection adds a spreading infection that converts mobs and terrain on NeoForge 1.21.1 – 1.21.4, with sonic tools to fight it back.
What it does
Infection starts when a player right-clicks a chosen position with the start infection item. Mobs that touch silent dirt are converted, and converted disquieters convert more mobs in turn. When a disquieter dies it leaves behind an infection cloud that spreads the infection further.
Silencers can spawn, and the skeletal creatures grow stronger as they kill, so the infection becomes harder to stop over time. Players can craft sonic tools from iron and diamond to fight it. The mod is published for NeoForge only, with two release versions, 1.21.1 and 1.21.4, and the latest file is 1.0.1 for 1.21.4, dated 2025-04-08. Every player and the server need a copy of the mod. It is released under All rights reserved and is not open source.

Sonic tools
