A trial spawner is a type of spawner found only within trial chambers. It spawns mobs in waves, which increase in number the more Survival/Adventure mode players are nearby. When all of its spawned mobs are defeated, it ejects a combination of consumable items and/or trial keys, then goes inactive for 30 minutes. It cannot be obtained as an item or moved by a piston. A trial spawner converts into an ominous trial spawner during an ominous trial.

Obtaining

Trial spawners cannot be obtained in Survival, even with Silk Touch, and can not be moved with a piston.

Natural generation

Trial spawners generate naturally in every chamber and every corridor of trial chambers, except for the entrance chamber.

Breaking

A trial spawner can be broken but it does not drop itself as an item and takes a long time to break. It can be obtained only via the Creative inventory, the /give command, or by using pick block whilst in creative mode.

Due to their high blast resistance, trial spawners are immune to explosions, but can still be destroyed by the ender dragon, the wither's block-breaking attack and blue wither skulls.

Usage

A trial spawner summons a limited number of mobs, scaled based on the number of nearby players. When these mobs are defeated, the spawner drops a reward for each player and enters a cooldown period.

Activation

The trial spawner has a required player range of 14 blocks. Any player in Survival or Adventure mode activates the spawner if the distance between the player's center and the spawner's center becomes less than the required player range, and the spawner has a direct line of sight to the player. Once activated, the spawner begins summoning copies of the mob set in it, and no longer requires the player to be within range or maintain line of sight.

The line of sight check for trial spawners can pass through transparent solid blocks, such as copper grates and glass. This differs from the line of sight check for hostile mobs, which cannot pass through these blocks.

Trial spawners do not activate if the game rule doMobSpawning is false.[1]

When a trial spawner first activates, it shoots spark-like particles up into the air. While active, it emits smoke and flame particles around itself and any entities it summons.

The light level around a trial spawner does not affect how it summons entities.

Mob spawning

A breeze and two skeletons spawning from a trial spawner.
See also: Trial Chambers § Trial spawners

When a player enters the trial spawner's range, the spawner attempts to spawn 1 mob every 40 game ticks (2 seconds). With 1 player, it does not spawn a mob if there are already 2 mobs from the spawner that are still alive. It spawns a total of 6 mobs before ejecting loot and going into cooldown. The number of living mobs required to prevent further mob spawning is called the simultaneous mob count. The number of mobs spawned before going into cooldown is the total mob count. These numbers are summarized in § Spawning values.

This duration of time between each mob being spawned is the spawn interval. If the spawner can't spawn a mob, it waits for the duration of the spawn interval and tries again. Once the number of living mobs spawned by the spawner has reached the simultaneous mob count, it stops trying to spawn mobs. Mobs spawned by the spawner do not naturally despawn, but the spawner does not detect or count living mobs from unloaded chunks. Therefore, moving mobs into unloaded chunks causes them to build up and the spawner to continue spawning more.

A trial spawner also stops spawning mobs if the number of living mobs spawned by it reached the total mob count. The spawner doesn't need to detect these mobs being alive, and therefore still counts them if they are in unloaded chunks. The spawner detects the death of the mobs only for the total mob count, and it always detects the death of the mobs even if it is not in a loaded chunk.

Both the simultaneous mob count and the total mob count increase if another player comes within the spawner's range. For each additional player present, the simultaneous mob count increases by 1, and the total mob count increases by 2. For example, with 2 players, 8 mobs spawn in total with 3 at once, and with 3 players, 10 mobs spawn in total with 4 at once.

If a player leaves the detection range of a trial spawner, these values do not scale back down.

The values described above are the default values used when trial spawners are placed manually. Naturally generated spawners in trial chambers use different values. Additionally, these numbers can be configured by modifying the block's NBT data.

Naturally generating trial spawners in trial chambers use different values for the spawn interval, the total mob count, and the simultaneous mob count. The quantity that the last 2 values change by with additional players is also different for different types of spawners. All naturally generated spawners attempt to spawn mobs every 20 game ticks (1 second), or every 160 game ticks (8 seconds) for the slow versions of the spawners. Additionally, naturally generated breeze spawners allow 1 breeze to exist at once (+0.5 for each additional player present) and stop after spawning 2 mobs (+1 for each additional player present). Baby zombie spawners allow 2 baby zombies to exist at once (+0.5 for each additional player present) and stop after spawning 6 mobs (+2 for each additional player present). All other spawners generated in trial chambers use the default value of 6 total mobs, plus 2 for each additional player present, and 3 simultaneous mobs, plus 2 for each additional player present. This is summarized in § Spawning values.

Spawning values

Type Spawn interval Total mobs (base) Total mobs added per player Simultaneous mobs (base) Simultaneous mobs added per player
Default values 40 game ticks (2 seconds) 6 2 2 1
Breeze 20 game ticks (1 second) 2 1 1 0.5
Baby zombie 20 game ticks (1 second) Default Default Default 0.5
All others in trial chambers 20 game ticks (1 second) Default Default 3 0.5
Slow versions (those that appear in chamber_8) 160 game ticks (8 seconds) Default Default 4 2

Mobs spawn in positions that have a line of sight to the spawner, in a 4-block spherical radius. This is different from the monster spawner, which has a larger, rectangular spawning box, and no line-of-sight requirement. Otherwise, the standard mob spawning rules apply (mobs cannot collide with blocks, guardians and elder guardians spawn only in water, etc.)

Completion

All mobs spawned by the trial spawner must be defeated before the trial spawner can drop loot. A mob is considered defeated when is either killed or transformed into another entity (excepting the transformation of creepers into charged creepers; the charged creeper must be defeated before completion of the trial spawner).

If a mob spawns more mobs upon death, only the initial mob must be defeated to complete the spawner (i.e. slimes and magma cubes).

Cooldown

Upon completion, the trial spawner enters a cooldown state for 30 minutes (36000 game ticks) before it can be activated again.[2]

Custom trial spawners

Using a spawn egg on a trial spawner sets the trial spawner's type to that egg's entity.

Trial spawners placed by players have the same loot data as those found in trial chambers.

Loot

When all mobs have been killed, the spawner waits 40 ticks (2 seconds). Then, every 30 ticks (1.5 seconds), it ejects random items from the loot table. It does this for every detected player. It has a 50% chance of picking the trial key, in which case it drops for all players. The other 50% of the time it drops one of the other items for each player. In Java Edition and Bedrock Edition, each trial chambers trial spawner contains 1 item stack, with the following distribution:

Ominous trial

Main article: Ominous Trial Spawner

A player with Bad Omen that is within the activation range of a trial spawner is given the Trial Omen effect, starting an ominous trial. During an ominous trial, trial spawners near a player with Trial Omen are converted into ominous trial spawners. When a trial spawner becomes ominous, all of its existing mobs are despawned. If the spawner was on cooldown and was not ominous before going on cooldown, the cooldown is skipped when becoming ominous.

Trivia

  • Trial spawners placed by hand have both spawn_potentials and spawn_data data. Right clicking the trial spawner with a spawn egg changes its spawn_data. Changing its spawn_potentials without removing its spawn_data causes the trial spawner to stop functioning.
  • If there are multiple entities listed within the spawn_potentials data of a trial spawner, the icon displayed by the trial spawner reflects the next entity to be spawned.
  • The line of sight check for trial spawners was implemented to prevent mobs from spawning outside of the room, or outside trial chambers' structure, such as inside caves.[4]
