Sculk Shrieker

A sculk shrieker is a redstone block found in the deep dark biome.

Natural generation
Sculk shriekers can be found within the deep dark biome.

Breaking
Sculk shriekers can be mined with any tool, but hoes are the quickest. It drops experience when mined without Silk Touch.

Usage
Sculk shriekers can "shriek" after getting enabled, which can happen by stepping on it, activating a nearby sculk sensor, or activating a redstone signal. This gives the player the darkness effect for 30 seconds.

If a sculk shrieker is activated within the deep dark biome, it creates a "warning" level to alert the Warden. A warden spawns when the warning level reaches level 3.

A sculk catalyst has a 1% chance of generating a sculk shrieker on top of a sculk block.
