A warden standing in a deep dark biome. It is bending forward and roaring.

Minecraft Snapshot 22w12a

A Minecraft Java Snapshot

Waaaaaaaaaaah! It's Wal... wait that's not it. It's the warden! The spooky, unfriendly (maybe it just wants a hug?) mob is making its way into our latest snapshot. 

Additionally, you'll be seeing some functionality for the sculk shriekers and some fancy new boats (they have chests).


New Features in 22w12a

  • Added Darkness mob effect
  • Added Sculk Shrieker functionality
  • Added the Warden mob
  • Added boat with chest
  • Added the Swift Sneak enchantment

Sculk Shrieker

  • Added functionality to the Sculk Shrieker: Notable for its boney appendages, this block responds to Sculk Sensors detecting vibrations by sending out a warning call to distant Wardens
    • Watch out when stepping on them, as they will feel that too and send out a call!
  • Initially it may take some time for a Warden to arrive, but you’ll hear it responding in the distance…
  • Once it’s close enough, a call from the Sculk Shrieker will summon the Warden nearby - be prepared!
    Added Warden mob


The horror of the Deep Dark! A creature with no eyes, roughly resembling the Sculk that can be found throughout the Deep Dark, the Warden is an unstoppable force of nature that inhabits this biome

  • Just like Sculk Sensors, these terrifying creatures use vibrations as a means to navigate their environment
  • When vibrations aren’t enough, they will also use a sense of smell to track down their prey - you can observe them sniffing their surroundings to get closer to unsuspecting players and mobs
  • To add to their myriad of ways to detect you, try not to get too close! If you collide with a Warden, it will notice you
  • In the Deep Dark, Wardens are everywhere - you just can’t see them. They slumber beneath your feet, and only dig out when enough Sculk Shriekers have alerted them of your presence
  • Watch your step: the more vibrations a Warden detects, the angrier it will get. You can hear and see this from how fast the souls in its chest are beating
  • Once a mob has pushed beyond the Warden’s anger threshold, it will face its prey and roar before charging
  • If, however, you keep the Warden from noticing you or getting angry for 60 seconds, it will dig back underground and despawn
  • They have a special interaction with thrown projectiles
    • If the Warden receives two projectile vibrations within 5 seconds of one another, it will grow angrier at the shooter
    • If the Warden receives a projectile vibration more than 5 seconds from the last projectile, it will not grow angrier at the shooter
    • This allows you to strategically distract the Warden without it getting angry while you take loot from nearby chests
  • Unfortunately for all players, Wardens will also disable shields when they hit them with their fists
  • They do not drop any loot
  • Wardens are powerful creatures, and it is often better to sneak around one that has emerged instead of taking it head on - you’ve been warned


  • A new mob effect unique to the Warden and Sculk Shrieker, which will afflict you with it when nearby
  • Lowers the gamma down at an equivalent of “Moody” while having this effect
  • In periodic pulses, will lower the overall brightness of the world so that the darkness creeps up against light sources
  • When the Warden is around, torches will be more important than ever!
  • A new Accessibility slider has been added in your Options menu called “Darkness Pulsing”
    • Controls how dark the Darkness effect gets when a Warden or Sculk Shrieker gives it to you, but will not affect the fog distance

Boat with chest

  • Lets you bring more stuff on your boat adventures
  • If you are in the boat, press the open inventory key to access the chest contents
  • If you are not in the boat, shift-right click to access the chest contents
  • If you break the boat the chest contents will spill out, like with other chests
  • Also works with hoppers, droppers, and other blocks that interact with chests
  • Like other chests, opening a boat chest or breaking the boat will anger piglins, since they think all chests belong to them

Swift Sneak

Imbue your leggings with this shiny new enchantment to move as fast while crouching as you would normally walk!

  • When applied, it will increase your movement speed while sneaking
  • Has 3 different levels with different speed increases
  • It is the first enchantment unique to leggings equipment!

Changes in 22w12a
