Sculk Shrieker

A sculk shrieker is a block found in the Creative inventory.

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

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

Trivia

 * The sculk shrieker's design was inspired by the human larynx.
