Warden

A warden is a hostile mob summoned by sculk shriekers located in the deep dark. It is completely blind, relying entirely on vibrations and its sense of smell to detect players and entities to attack, and digs down to despawn if it does not detect anything for 60 seconds and if it doesn't have a name. If a warden successfully detects a target, it rapidly strikes them with its arms, or fires damaging sonic beams which pass through blocks and ignore armor, shields, as well as all enchantments.
