Ominous Trial Spawner

An ominous trial spawner is a variant of the trial spawner that gives better loot and spawns more armored mobs (when applicable). It replaces a normal trial spawner when a player having the Trial Omen effect approaches the trial spawner, during an ominous trial. The ominous trial spawner can reward players with ominous trial keys instead of normal trial keys.

Obtaining

Ominous trial

Trial spawners convert to ominous trial spawners if a player with the Trial Omen effect enters the 14 block detection area and is in the line of sight of the trial spawner. This also happens when the player has the Bad Omen effect, which gets converted into Trial Omen. 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. The ominous trial spawner then immediately becomes active. An inactive ominous trial spawner converts back into a regular trial spawner after cooling down for 30 minutes.

The ominous trial spawner cannot be obtained as an item, because it is technically a block state of the normal trial spawner, not a separate block. It can only be obtained by using commands, such as:

Java Edition:

• /give @s minecraft:trial_spawner[block_state={ominous:"true"}]
• /setblock x y z minecraft:trial_spawner[ominous=true]

Bedrock Edition:

• /setblock x y z trial_spawner ["ominous"=true]

Breaking

An ominous trial spawner can be broken, but it does not drop itself as an item, and it takes a long time to break.

Due to their high blast resistance, ominous 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

The ominous trial spawner is similar to the trial spawner, but releases more difficult mobs and ejects more powerful loot.

Mob spawning

Ominous trial spawners converted from trial spawners that generate naturally in trial chambers spawn mobs with (better) weapons and wearing armor. Ominous Trial Spawners with mobs that are unable to wear equipment spawn double the total mob count over the course of the challenge. These spawners also spawn an additional mob out at once during their challenge.

Each armor set consists of only a chestplate and helmet with each piece having a 50% chance of being missing. All armor is enchanted with Fire Protection IV, Projectile Protection IV, and Protection IV. Mobs don't drop the armor on death or upon conversion to a drowned. The armor is selected from:

• Chainmail armor with bolt armor trim in copper (4 in 7)
• Iron armor with flow armor trim in copper (2 in 7)
• Diamond armor with flow armor trim in copper (1 in 7).

Melee mobs spawn with a weapon selected from:

• Iron sword (4 in 7)
• Iron sword with Sharpness I (1 in 7)
• Iron sword with Knockback I (1 in 7)
• Diamond sword (1 in 7).

Ranged mobs spawn with a bow with:

• no enchantment (2 in 4)
• Power I (1 in 4)
• Punch I (1 in 4).

Ominous trial spawners converted from manually placed trial spawners continue to spawn the same mob as the trial spawner.

Projectile spawning

When at least one player is within the activation range of an ominous trial spawner, every 8 seconds it spawns ominous item spawners above any such player or any mob that was spawned by this ominous trial spawner. The location where it should spawn is determined by first performing a raycast from the feet of the entity to a random height between 2 and 6 blocks above the entity. If it hits a block, this block is used, otherwise the end of the line is used. Which block can be hit is determined by the same algorithm as the 3rd person camera. The item spawns in the center of the block below it, unless the block has a collision box. The ominous item spawner displays a projectile for 3 to 6 seconds before shooting that projectile downwards. Each ominous trial spawner has a set of 2 projectiles it spawns, one of which is a lingering potion. The lingering potion effect is selected randomly from one of the following (all with equal chance):

• Wind Charged
• Oozing
• Weaving
• Infested
• Strength
• Speed
• Slow Falling

The second projectile is randomly selected from one of the following (again, all with equal chance):

• Arrow
• Arrow of Poison
• Arrow of Slowness IV
• Fire charge
• Wind charge

Loot

Ominous trial spawners in trial chambers eject different (better) rewards compared to the non-ominous state.

Like the normal trial spawner, it ejects the loot once for each detected player. Instead of trial keys, an ominous trial spawner has a 30% chance to eject ominous trial keys, in which case it drops for all players. The other 70% of the time it drops one of the other items for each player. In Java Edition and Bedrock Edition, each trial chamber ominous trial spawner contains 1 item stack, with the following distribution:

Item	Stack Size	Weight	Chance	Avg. per spawner	Avg. # spawners to defeat
Ominous Trial Key	1	30⁄100	30.0%	0.300	3.3
Baked Potato	2–4	21⁄100	21.0%	0.630	4.8
Steak	1–2	21⁄100	21.0%	0.315	4.8
Golden Carrot	1–2	14⁄100	14.0%	0.210	7.1
Potion of Regeneration	1	7⁄100	7.0%	0.070	14.3
Potion of Strength	1	7⁄100	7.0%	0.070	14.3

Ominous trial spawners converted from manually placed trial spawners continue to drop the loot of a normal trial spawner (see Trial Spawner#Loot).

Data values

The ominous trial spawner is technically a block state of the trial spawner. Therefore, it has the same data value structure.
