Post-generation

A sculk catalyst has a 1% chance of generating a sculk shrieker on top of a sculk block.

Usage

Sculk shriekers can "shriek" after being enabled, which can happen by a player stepping on it, activating a nearby sculk sensor, or activating a redstone signal. The shrieker shrieks for exactly 90 game ticks (4.5 seconds). After the shrieking ends, all players in survival mode within 40 blocks are given the Darkness effect for 12 seconds. Sculk sensors pass on the warning to shriekers only if the sound comes from a player action.

Sculk shriekers have a 10 second cooldown per player. This means that if a player triggers one shrieker, then triggers another shrieker within the cooldown period, that shrieker does not activate. The cooldown period includes the 4.5-second shrieking, meaning the shrieker can shriek again 5.5 seconds after the previous shrieking ends.

A sculk shrieker has a spherical range of 16 blocks. When a shrieker is activated via redstone power, if there is a player within 16 blocks, the shrieker starts shrieking; if there is no player within range, the shrieker does not shriek.

Spawning wardens

Each time a sculk shrieker is activated, it adds 1 to a "warning" level to alert the warden. The warning level is specific to each player, not each sculk shrieker, meaning that the same player can activate a different skulk shrieker for each of the three times, and a warden still spawns on the third 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.

When a player's warning level reaches level 3, the sculk shrieker attempts to spawn a warden after its shrieking ends. Up to 20 attempts are made to spawn a warden within a 11×13×11 box centered on the shrieker. If there isn't another warden within 48 blocks, and the light level is lower than 11, a warden emerges from the ground.

If the player that triggered the sculk shrieker is outside the shrieker's range when the shrieking ends, or if the shrieker is destroyed before it stops shrieking, the sculk shrieker does not apply the Darkness effect to any player, and it does not spawn a warden. The player's warning level still increases by 1.
