Sculk Infection
Sculk Infection adds sculk-themed blocks, items and three advanced mobs to Minecraft, with the aim of increasing sculk presence in the world.
What it does
The mod introduces new sculk-themed content, including blocks and items. Several of its mobs are new, and some are existing mobs that have been given sculk versions. The new entities spawn outside the Deep Dark biome as well, though still below deepslate, so sculk creatures can turn up in more places than before.
The main goal is to spread sculk across the game world. The mod is built for Fabric and needs Fabric API to run. Files for 1.20 – 1.21.1 are published for Fabric, and the mod works on NeoForge 1.21 and Forge 1.20 through Sinytra Connector, which requires the Forgified Fabric mods folder placed instead of Fabric API. Installation covers the server and each player's game. The code is not open source; the mod is released under All rights reserved.
Key features
Sculk-themed blocks and items
New blocks and items are themed on sculk, adding to the decorative and crafting options of the sculk world.
Advanced sculk mobs
Three new sculk-themed mobs are added, along with sculked versions of existing mobs and some entirely new creatures.
Worm and Arbiter loot
Worms grab players, and Arbiters, which replaced the Watchers, drop Worm Mucus and Watcher Tendrils.
Crulk spawn control
A config value from 0 to 100 sets how many Crulk a single Watcher summons and how often Crulk appear naturally; 100 disables natural Crulk altogether.
Sculk Sludge and Echo Shells
Echo Shells and Sculk Sludge are mined regularly, and Sculk Sludge must be in an uninhabited area to be collected.
