Sculk Catalyst Overrun
Sculk Catalyst Overrun V1.0
Sculk Catalyst Overrun transforms your Minecraft Bedrock world into a growing sculk infection where every mob death strengthens the sculk’s power.
When a player kills any mob, a vanilla Sculk Catalyst appears at the death location. The catalyst converts the mob’s XP into sculk charges, which spread outward and transform nearby blocks like stone, dirt, and deepslate into:
- Sculk
- Sculk Veins
- Sculk Sensors
- Sculk Shriekers
As the sculk spreads, it also increases the local mob spawn rate, especially Creepers, making infected areas far more dangerous over time.
This addon uses only vanilla Minecraft blocks and mechanics, ensuring full compatibility and a natural gameplay experience.
