When a player's warning level reaches level 4, the sculk shrieker attempts to spawn a warden after its shrieking ends. 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. This means that if a player triggers one shrieker, they are completely unable to trigger any other shrieker within 10 seconds. Naturally generated sculk shriekers have a 10-second cooldown per player. After a warden is summoned, a player's warning level does not reset back to 0, meaning multiple wardens can be summoned.

After the shrieking ends, all players in Survival or Adventure mode within 40 blocks are given the Darkness effect for 12 seconds. If a player does not activate any sculk shrieker, the warning level decreases by 1 every 10 minutes (12000 ticks). 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. Each time a naturally generated sculk shrieker is activated, it adds 1 to a "warning" level to alert the warden.

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. Sculk shriekers that naturally generate in the deep dark biome are capable of inflicting the Darkness effect upon players and summoning wardens. The shrieker shrieks for exactly 90 game ticks (4.5 seconds).Ī set of shriek particles emitted by a sculk shrieker. However, a sculk sensor cannot activate the sculk shrieker if the line between the two contains a wool block. 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. A sculk shrieker activates when any player stands on the black part in the center of the block, even when sneaking. Sculk shriekers "shriek" after being activated. These shriekers do not summon the warden. For more information, see Breaking § Speed.Ī sculk catalyst has a 1% chance of generating a sculk shrieker on top of a sculk block.
