A sculk shrieker is a sculk block that "shrieks" if any player touches its top (even indirectly) or activates a nearby sculk sensor. Only players can trigger it.

Naturally-generated sculk shriekers appear only in the deep dark biome. They also inflict Darkness and may summon a warden if triggered, but shriekers placed by players or sculk catalysts are completely inert and harmless.

Obtaining

Breaking

A sculk shrieker can be mined with any tool, but hoes are the quickest. It drops itself only if mined with any tool enchanted with Silk Touch. If mined with a non-Silk Touch tool, it drops 5 experience instead. When a sculk shrieker is broken, it loses the ability to summon wardens, even if mined with Silk Touch.

Natural generation

Sculk shriekers can be found infrequently within the deep dark biome, and they are much more common within ancient cities. All naturally generated shriekers can summon wardens.

Post-generation

A sculk catalyst has a 1% chance of generating a sculk shrieker on top of a sculk block. These shriekers do not summon wardens.

Usage

Sculk shriekers "shriek" after being activated. A sculk shrieker activates when any player stands on the black part in the center of the block, even when sneaking. Sculk shriekers are also activated by any sculk sensor triggered within an 8-block spherical radius of itself, but only if the vibration was caused by a player. However, a sculk sensor cannot activate the sculk shrieker if the line between the two contains a wool block. The shrieker shrieks for 90 game ticks (4.5 seconds).

Spawning wardens

Sculk shriekers that naturally generate in the deep dark biome are capable of inflicting the Darkness effect upon players and summoning wardens. In Bedrock Edition, when a warden is summoned from a sculk shrieker, the spawn event minecraft:spawn_emerging is applied to it. This spawn event is what allows the warden to play the emerging animation with the minecraft:behavior.emerge component. If a sculk shrieker is placed by a player or generated via a sculk catalyst, the tag can_summon is set to false, and therefore a warden cannot be summoned and Darkness cannot be inflicted by that sculk shrieker.^[1] The top texture of shriekers with the tag set to false are different from the ones with the tag set to true. The "souls" on the "dummy" shriekers spin slowly, more dim and spin counter-clockwise, as opposed to the "souls" on the real ones spinning faster, glow more brightly and spin clockwise. Each time a naturally generated sculk shrieker is activated, it adds 1 to a "warning" level to alert a warden. The warning level is specific to each player, not each sculk shrieker, meaning that the same player can activate a different sculk shrieker for each of the four times, and a warden still spawns on the fourth activation, even though any particular shrieker had been activated once. If a player does not activate any sculk shrieker, the warning level decreases by 1 every 10 minutes (12000 ticks). In multiplayer, all other players in a 16-block spherical radius are also "blamed" for a sculk shrieker's activation, and all blamed players have their warning level set to one more than the highest warning level among blamed players, and all of their warning level timers are reset. After the shrieking ends, all players in Survival or Adventure mode within 40 blocks are given the Darkness effect for 12 seconds. After a warden is summoned, a player's warning level does not reset back to 0, meaning multiple wardens can be summoned.

Naturally generated sculk shriekers have a 10-second cooldown per player. This means that if a player triggers one shrieker, they are completely unable to trigger any other shrieker within 10 seconds. The cooldown period includes the 4.5-second shrieking, which means 5.5 seconds after the previous shrieking ends, the player can activate sculk shriekers again.

When a player's warning level reaches level 4, the sculk shrieker attempts to spawn a warden after its shrieking ends. If the shrieker is broken before it ends shrieking, a warden will try to spawn immediately. Up to 20 attempts are made to spawn a warden within an 11×13×11 box centered on the shrieker. If there isn't another warden within 24 blocks, a warden emerges from the ground. The warden always spawns at the highest available block. If all 20 spawning attempts fail, a loud roaring sound is played. Spawning a warden does not decrease the player's warning level, so a warden can be immediately summoned again after the 10-second cooldown. However, the warning level does not increase above 4.

In Peaceful difficulty or in Java Edition, if the game rule spawn_wardens is set to false, naturally generated sculk shriekers behave as if they are placed by a player: they do shriek, but there is no shrieking cooldown, the player's warning level does not increase, no Darkness effect is inflicted, and no warden spawns.

If the player that triggered the sculk shrieker is outside the shrieker's range when the shrieking ends, the sculk shrieker does not apply the Darkness effect to any player. The player's warning level still increases by 1.

It is possible to make a warden spawn from a distance, by shooting a projectile into the direction of known sensors that are near shriekers.

The warnings have unique subtitles at different levels of warning:

1. Warden approaches
2. Warden advances
3. Warden draws close
4. Warden takes notice angrily

The subtitles for warning level 4 are shown only if the warden fails to spawn. This subtitle is often seen while there is already a warden nearby.

Vibration filter

Because sculk shriekers activate only in response to vibrations sent from nearby sensors caused by a player, it has the potential be used for systems that require player-only vibration filters. Activated sculk shriekers can also be detected by an observer, making it useful for sending a pulse to redstone components. This works even if the shrieker and sensor are both waterlogged.

No sculk sensor responds to the sound of a shrieker, so they cannot be used to re-emit player vibrations a long distance, but blocks of amethyst can re-emit all vibrations and then a sculk shrieker at the destination can filter for whether this vibration was originally player-caused.

Some vibrations do not trigger a sculk shrieker even though they may seem player-caused: one is the vibration of passing by while riding a minecart. Even passing through a tripwire while in a minecart does not trigger the shrieker.

Piston interactivity

Sculk shriekers cannot be moved by pistons or sticky pistons.

• The sculk shrieker's design was inspired by the human larynx.^[8]
• The old trypophobia shrieker was a combination of the modern day shrieker and scrapped sculk jaw as it would both scream and show teeth.^[9]
