Warden

The warden is a hostile mob introduced in the Caves & Cliffs update. It is the first blind mob in Minecraft and spawns in the Deep Dark biome in 1.18. They move toward vibrations sensed through their ears in the surrounding environment. Projectiles, player footsteps, and more can alert a warden, causing it to investigate. Sneaking does not trigger vibrations. The warden is powerful, intended to be fled from, not engaged in combat by a player.

Appearance
A warden is about 3.5 blocks tall, compared to an iron golem at 3. It is made of sculk and a bone-like material, with ears like the top of the Sculk Sensor. It has a glowing heart on its chest.

The warden's heartbeat is audible and visible, and the heart flashes as the Warden becomes stronger from attacks. Its entire body is made out of sculk.

Spawning
The warden spawns in the Deep Dark Caves biome. It can also be spawned using spawn eggs or using commands. It needs at least a 2x3.5x1 space to spawn naturally.

Behavior
The warden is a hostile mob, and the first completely blind mob in the game. The warden has acute senses for sound and vibration. It relies on echolocation. A warden attacks any mob that produces a sound or vibration, except for another warden. If the player steps onto any kind of sculk block, the warden charges at the player and attacks. The warden also charges at any player who tries to go near it or attack it.

Players can sneak to avoid alerting the warden to their presence. The warden can be distracted by throwing snowballs and eggs, or by shooting projectiles.

A brief dimming of light may alert the player of the presence of a warden.

Fighting a warden is not recommended. It can detect invisible entities. When the Warden has been attacked repeatedly, it ignores all distractions and targets the attacker. At this point the warden increases its charging speed. Attacking the warden makes it stronger and faster, and its heart flashes more. The warden deals significant damage ( hearts), enough to kill a player wearing a full set of unenchanted netherite armor in two hits. A player wearing weaker armor or no armor would die from one hit.

The warden burns when exposed to sunlight. Upon death, a warden drops a trophy item or nothing. It can resist knockback.
