Sculk
minecraft:sculkSculk is a decorative block found abundantly in the Deep Dark biome, or generated wherever a mob dies within range of a sculk catalyst. It features an animated texture with faintly glowing spots but produces no light of its own. The block has low hardness and is best broken with a hoe, dropping experience when mined without Silk Touch.
FAQ
Where does Sculk naturally spawn?
Sculk generates in patch formations throughout the Deep Dark biome and can also be found in Ancient City loot chests.
How does Sculk spread?
When mobs die within 8 blocks of a sculk catalyst, sculk blocks replace nearby replaceable blocks like stone, dirt, and various ores, converting the area into a sculk patch.
What's special about mining Sculk?
Sculk drops 1 experience point when destroyed with a tool that lacks Silk Touch, and drops itself when destroyed with a Silk Touch tool.
Does Sculk make noise or attract the Warden?
No. Early development prototypes let players trigger loud noises simply by stepping on sculk, attracting the Warden, but this mechanic was removed before release for being unfairly punishing.
