Sculk Contagione
by Clomclem
Sculk Contagione makes the Sculk blocks of vanilla Minecraft spread more aggressively, and it is a Fabric mod for 1.21.1 that requires Fabric API.
What it does
Sculk spreads further and converts nearby blocks into Sculk more often than in vanilla. Sculk catalysts that spread convert almost any block into Sculk, and Sculk shriekers can summon Wardens when they are placed in a spawn-enabling setup. Sculk also absorbs non-Sculk items that land on it, and it deals damage to entities that walk across it unless they wear boots.
The mod was inspired by Sculkhunt and the Sculk Horde concept, with the aim of a vanilla-esque infection mod. Timings, spread amounts and related behavior can be adjusted through gamerules, which are documented by the author, so a world can be made milder or harsher without editing code.
Fabric API is required. A server running it needs every connecting player to have it too. The code is under the MIT License and is open source, with a public source repository and issue tracker. Builds cover 1.20.4 – 1.21.1 across five release versions, and the latest Fabric file is 1.1.0+1.21.1 for 1.21.1, published on 2024-09-15.
Key features
Invasive Sculk spread
Sculk grows into neighboring blocks more readily than in vanilla, changing terrain over time.
Item absorption
Sculk absorbs non-Sculk items that fall onto it, removing them from the world.
Boot-dependent damage
Entities that walk on Sculk without boots take damage, so footwear matters in infected areas.
Warden spawning from shriekers
Sculk shriekers can trigger Warden spawns, adding a risk to Sculk areas.
Tunable through gamerules
Spread timings and amounts are set with gamerules, letting world owners adjust the infection.
