Breeze & Wind Charges
- The Breeze now avoids jumping into dangerous blocks or air
- Wind Charges no longer collide with End Crystals
Ominous Events
- Bad Omen has been expanded to give access to an optional experience in Trial Chambers
- These optional experiences accessed through Bad Omen are now known as Ominous Events
- They are more challenging than usual, and are designed to shake up the experience in unique ways
- Illager Raids are an example of an existing Ominous Event
- Bad Omen is getting some changes with this redesign:
- It has a new, shadowy icon and a sound for being applied to the player
- It no longer triggers a Raid directly when entering a village
- Instead, it will transform into a Raid Omen variant with a duration of 30 seconds
- Once the Raid Omen expires, a Raid will start at the location the player gained the Raid Omen
- Like any other effect, players can drink a Bucket of Milk to clear the Raid Omen to prevent the Raid from starting
- It is no longer given to players that defeat a Raid Captain outside a Raid
- Instead, players can gain access to Bad Omen by consuming a new Ominous Bottle
Ominous Bottle
- An item which can be consumed by players to receive the Bad Omen effect for 1 hour and 40 minutes
- Comes in 5 variations, one for each Bad Omen level
- The bottle breaks when consumed
- Can be stacked to 64
- Can be found uncommonly in any Vaults that are unlocked with Trial Keys, and is dropped by Raid Captains when defeated outside a Raid
Ominous Trials
- A new Ominous Event that can be accessed by exploring a Trial Chamber with Bad Omen
- This event will have players facing more powerful Trial Spawners if they dare!
Trial Omen
- A variant that Bad Omen can transform into
- This occurs when the player is within detection range of a Trial Spawner that is not Ominous
- The Trial Omen has a duration of 15 minutes multiplied by the transformed Bad Omen’s level
- Players that have Trial Omen are surrounded by ominous particles
Ominous Trial Spawner
- A more powerful active phase of the Trial Spawner with unique challenges and rewards
- Provides a more challenging experience that advanced players can opt into for better rewards
- If a Trial Spawner detects a player that has the Trial Omen effect, the spawner will become Ominous if:
- It is not in cooldown
- Or, it is in cooldown but was not Ominous during its last activation
- Making it Ominous this way will bypass the cooldown
- While active, it will:
- Glow blue instead of orange
- Emit soul flames instead of normal flames
- Very commonly spawns mobs with equipment if they can wear it
- The equipment these mobs wear have armor trims applied from the Trial Chambers
- Known issue: these mobs can currently drop their equipment on death, but they will not in the future
- Periodically spawn potions and projectiles on top of unsuspecting players and mobs
- Based on their location, spawners in an area will select a random set of projectiles to spawn
- These projectiles will always include a single type of Lingering Potion from a set of possible effects
- Becoming Ominous will despawn any existing mobs it spawned and reset its challenge
- It will stay Ominous until it has been defeated and its cooldown has finished
- When defeated, it will eject a different set of loot to normal Trial Spawners
Ominous Trial Key
- A new variant of the Trial Key which can only be obtained by defeating an Ominous Trial Spawner
- They can be used to unlock Ominous Vaults
Ominous Vault
- A variant of Vaults that have a different texture and emit soul flames instead of normal flames
- These can be found throughout the Trial Chambers in harder to find places and require an Ominous Trial Key to unlock
- These Vaults hold a more valuable set of rewards than the standard Vaults unlocked by Trial Keys
Mob Effects
- The following effects have been added:
- Wind Charged
- Affected entities will emit a wind burst upon death
- Brewed with an Awkward Potion and a Breeze Rod
- Weaving
- Affected entities will spread Cobweb blocks upon death

- Oozing
- Affected entities will spawn two Slimes upon death
- Brewed with an Awkward Potion and a Slime Block
- Infested
- Affected entities have a 5% chance to spawn 1-2 Silverfish when hurt
- Brewed with an Awkward Potion and a Stone block
- Wind Charged
- These effects can be encountered while taking on an Ominous Trial Spawner
- Some mobs are immune to these effects
- Slimes are immune to Oozing
- Silverfish are immune to Infested
Trial Chambers Loot
- The loot found within Trial Chamber Vaults has been adjusted
- Standard Vaults will give slightly less items of high quality, but also include the following changes:
- Ominous Bottle I – II can be found
- Flow Banner Pattern, Flow Armor Trim Smithing Template, and Heavy Core can no longer be obtained
- Guster Banner Pattern and Bolt Armor Trim Smithing Template remain exclusive to standard Vaults

- Flow Banner Pattern and Flow Armor Trim Smithing Template
- Wind Burst, Breach and Density Enchantments for the Mace

- The loot ejected from Trial Spawners have been adjusted

Trial Spawner
- All spawners now increase the amount of mobs present at once by 0.5 for each additional player, down from 2
- Baby Zombie spawners now only have 2 mobs present at once for its baseline, down from 3 mobs
- Can now only activate when a player is in line of sight
Trial Chambers

- Reduced amount of Trial Spawners in corridors
- Updated layout and placements of Vaults
- Placed Ominous Vaults in chambers, intersections, at the ends of corridors
