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!
• Please note: There are some changes that are already in the Java Edition Snapshot that haven’t made it here, but we are working on more tweaks that will be included in the upcoming Previews.

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 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 Trial Spawner

• A more powerful active phase of the Trial Spawner with unique challenges and rewards
  • Provides a more challenging experience that 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
  • 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
  • More commonly spawn mobs with equipment if they can wear it
  • The equipment these mobs wear have Armor Trims applied from the Trial Chambers
  • Periodically spawn potions and projectiles on top of unsuspecting players and mobs
• 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 than normal Trial Spawners

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
• Known Issue: Vaults in Trial Chambers may generate without loot and cannot be opened by Trial Key

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 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

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 transformed Trial Omen has a duration of 15 minutes multiplied by the previous Bad Omen level
• Players that have Trial Omen are surrounded by ominous particles

  • Brewed with an Awkward Potion and a Slime Block
• Infested
  • Affected entities have a 5% chance to spawn 1-2 Silverfish when hurt

• These effects can be encountered while taking on an Ominous Trial Spawner
• Spawners in an area will select a unique effect for the duration of their challenge, and drop them as lingering potions onto mobs and players nearby
• Some mobs are immune to these effects
