Sculk Warden

"This is a sculk warden. A completely blind monster summoned by sculk shriekers that rely of vibrations and smell to identify anyone who can stand on their way. Being extremely powerful with a high health and extremely dangerous force of pain, we could be screwed up. Really screwed up. That reminds me of a tank from the two Left 4 Dead games."

--Su Ji-Hoon, Congressman Andrews

The Sculk Warden is a hostile mob summoned by sculk shriekers. They are completely blind, and thus rely on vibrations and their sense of smell to identify the player and other mobs. They are extremely powerful, having the highest health and dealing the most damage of any mob in the game, including bosses.

In When the Cold Breeze Blows Away, most of them are first appear in Exegol and some parts of ancient city.

Believe about special ability, the Coalition of the Red Phoenix created the sculk  shriekers as they, Beleninsk Pact and New Central Powers can summon them after the Coalition of the Red Star also created them.
