SubVirus
by SubTeam
SubVirus brings an Infected dimension with six infected classes, each with its own buffs and debuffs, plus custom potions and blocks.
What it does
SubVirus adds a custom dimension called Infected, in which six infected classes are found. A single class carries its own buffs and debuffs, and drinking a potion can switch a player from one class to another. Three custom potions can be crafted, though the Panacea Potion does not yet work correctly.
The mod is a Fabric world generation and adventure addition. It runs on the client and the server, so both the server and every player need it. It requires Geckolib, which is used to implement its custom armor, and it is released under the MIT License as open source for 1.21.8 only. Its latest Fabric file, 1.0.2, was published on 2026-03-01 on the alpha channel, and its source code is public.
