Sculk – Minecraft Wiki

Sculk is a block found abundantly in the deep dark or converted from other blocks by a sculk catalyst. Like most of the rest of the sculk family it drops experience when broken by a tool that is not enchanted with Silk Touch. Sculk blocks can be mined with any tool, but hoes are the quickest. It always drops 1 experience if mined without Silk Touch. Sculk are naturally generated in patch formations within the deep dark biome. Sculk blocks generate when a mob dies within 8 blocks of a sculk catal
