A sculk catalyst is a block that generates Sculk features around it when a mob is killed nearby.



Sculk catalysts can be mined with any tool, but hoes are the quickest.

Sculk catalyst activating

Sculk catalyst detection range

It turns the blocks around the dead Mob into Sculk or Sculk Vein.

When a sculk catalyst is in range of where a mob dies, it blooms, giving off soul particles and creates a patch of sculk with sculk veins around that location. Some of the blocks that the sculk catalyst can replace with sculk blocks are grass blocks, dirt, coarse dirt, stone, deepslate, andesite, diorite and granite.
