Warden

The warden is a hostile mob summoned by sculk shriekers in deep dark biomes. It has high health and deals the highest melee damage of all mobs. It can also fire ranged sonic boom attacks that bypass blocks and almost all damage-reducing items, including enchanted armor. The warden is completely blind and relies on vibrations and its sense of smell to detect players and mobs to attack.

Spawning
Wardens do not use standard mob spawning mechanics. Instead, they are spawned when a player activates naturally generated sculk shriekers four times, and if there isn't already another warden within 24 blocks of it. When a warden spawns, it emerges from the ground near the shrieker that summoned it, taking about 6.7 seconds to do so and being completely invulnerable until fully emerged.

The warning count for sculk shriekers is specific to each player, rather than each sculk shrieker. This means that the player can activate four different shriekers in different locations, and a warden still emerges after the fourth activation.

Up to 20 attempts are made to spawn a warden within a 11×13×11 box, which is centered on the shrieker. During each attempt, the game picks a random Y column, then the game picks the topmost block in that column with a top surface with full collision, and the block above must have no collision. Unlike other hostile mobs, light level does not have an effect on warden spawning. Like other mobs, the spawning warden cannot collide with any existing entities or liquids.

$$, warden spawning can be toggled on or off with the game rule.

Drops
Wardens drop a single upon death. They also drop experience if killed by either a player or a tamed wolf.

Behavior
After spawning, wardens wander randomly around the world and move toward nearby vibrations originating from players, mobs, and non-mob sources including projectiles and minecarts. The warden also periodically sniffs the area around it, allowing it to zero in on targets even if they don't create vibrations. As wardens sniff, pick up vibrations, or are touched by other players/mobs, they become increasingly agitated.

Passive
The warden can fit inside of any space that is 1 block wide and 3 blocks tall, allowing it to chase players and mobs through small corridors.

Wardens are immune to damage from fire or lava, and do not take knockback. They can pathfind through blocks that are usually avoided by other mobs, including rails, powder snow, and magma blocks.

The warden, whether angered or not, gives 12 seconds of Darkness to all players within a 20 block radius of it every 6 seconds. The souls in its chest make a low, throbbing heartbeat that occurs in tandem with the Darkness effect. The heartbeat speeds up as the warden becomes increasingly agitated. The warden prefers to track down the most suspicious targets, rather than the ones closest to it.

Detecting mobs
The warden listens to all vibrations within a 16 block radius, except those from other wardens, armor stands, dying mobs, and players in Creative or Spectator mode. Like with sculk sensors, they cannot detect a sneaking player who's walking, falling, or shooting a projectile. The warden has a 2-second cooldown between detecting vibrations.

When idle, wardens sniff the surroundings to detect nearby mobs every 5 to 10 seconds. At the end of the sniffing animation, which takes around 4.2 seconds, the warden moves toward the location of the nearest mob or player within a box of approximately 49x51x49 centered on itself.

Anger
Wardens keep track of how angry it is at each suspect as a number from 0 to 150. When the warden notices a vibration, it adds anger to the mob that caused the vibration. It adds 10 anger if the vibration was from a projectile, or 35 anger for other vibrations. However, if two projectiles are heard by the warden within five seconds, it instead adds the full 35 anger toward that player/mob. Wardens do not add anger toward a mob/player if the projectile was shot from than 30 blocks away, although the projectile does count toward the counter of two projectiles. Anger decays at a rate of 1 per second and immediately clears if the targeted player switches to Creative or Spectator mode, the target or warden leaves the dimension, or if the target dies.

The warden adds 35 anger toward any mob that directly touches it. This effect has a 1-second cooldown.

When it finishes sniffing, the warden adds 35 anger to the nearest mob or player within 6 blocks horizontally and 20 blocks vertically.

Once a warden reaches 80 anger with a target, it roars for 4.2 seconds, adds another 20 anger, and pursues the target. In this angered state, the warden chases the target normally despite being blind. The warden also enters its hostile state and adds 100 anger if directly attacked by a mob. If the attacking player or mob is within 5 blocks, it skips its roaring animation altogether and immediately gives chase.

The warden is biased toward player vibrations, attacks and contact - even if a warden is angrier at another mob, it still attacks the player first as long as they have angered the warden as well. This is not true of any other mob.

After 60 seconds of being "calm" and not detecting any vibrations or sniffing any mobs, it burrows back into the ground and despawns, unless the warden has been named. If the warden is floating on a liquid, it instead immediately despawns without any burrowing animation. During its emerging/burrowing animation, the warden can take damage only from, though it can still be pushed by entities, pistons, or liquids. Named wardens do not dig or despawn.

Attacks
The warden's melee attack has a cooldown of 0.9 seconds and disables shields for 5 seconds, dealing to  HP depending on the difficulty.

If a warden cannot reach its target, it switches to its ranged attack: a powerful sonic boom. It does so when the following are true:
 * It has been 10 seconds since the warden detected the target
 * It has been 5 seconds since the warden last used a melee or ranged attack
 * The target is within 15 blocks horizontally and 20 block vertically of the warden.

The sonic boom directly attacks the target, passing through blocks and other mobs without damaging them. The warden takes 1.7 seconds to charge up, then unleashes the attack, which instantly hits the target as long as the target is within attack range. It cannot be dodged. The attack takes an additional 1.3 seconds to cool down before the warden can use melee attacks again for a total of 3 seconds. The sonic boom is visible via green-blue particles that are projected out of the warden's chest. This attack bypasses shields, armor, enchantments, blocks, and even the wither armor of the wither. Only the Resistance effect can reduce this attack's damage.

Wardens have entity data associated with them that contains various properties.



Advancements
There are currently no advancements associated with killing a warden. The warden is intended to be a natural disaster that is nearly impossible to kill and best avoided. Therefore, killing a warden doesn't count for the Monster Hunter advancement, nor is it needed to receive the Monsters Hunted advancement.

Trivia

 * Although the warden is supposed to be blind, spectating it reveals that it still has normal vision.
 * The concept for the warden was originally planned for the Nether Update as a "blind piglin that could only respond to sounds" that could be found within a "new biome".
 * Some previous names being considered for the warden were the shade, the stalker, and the hollowed.
 * The stalker iteration was tall and asymmetrical with a glowing core (sometimes referred to as a chest crystal ). It occurred in totems throughout the deep dark. The stalker would stand completely still to trick players into taking its core and aggravating it, and could transform into a form one block high form to prevent players from escaping through small tunnels. This iteration, specifically its appearance and transformation mechanic, felt clunky and was more goofy than scary, so it was scrapped by the Mojang developers.
 * The hollowed was designed with the intent of inciting trypophobia and had white flesh with holes in it. The developers deemed that iteration too gory and had to be toned down.
 * In the sixth episode of The Secrets of Minecraft, it was jokingly revealed that the warden's personal names are "Jonathan" and "William", depending on the scene, similar to how the player, ender dragon, and wither all have personal joke names. "Warden" itself was also jokingly broken down into "War! Dens!" in the description.
 * "Jonathan" can be seen on a blackboard for name suggestions alongside "the stalker" and "the hollowed".
 * It jokingly explained that the name "warden" was the result of calling it "William" and spelling it wrong.
 * In the tenth episode, both names were used when the Narrator spotted the warden behind him.
 * Brandon Pearce stated in a tweet that the souls in the warden's chest is incredibly important to its lore.
 * He also stated that the warden is inspired by the "monster" heard at the end of the music disc "11".
 * Coincidentally, in the spin-off game, Minecraft: Story Mode, there is an unrelated character also named The Warden.
