Minecraft:Enchantments<ref name=noexp>Template:Bug</ref>

• Three new enchantments have been introduced that are unique to the Minecraft:mace.
• Minecraft:Breach
  • Rare enchantment, accessible in the Minecraft:enchanting table and on Minecraft:enchanted books in loot.
  • Has 4 levels.
  • Maces enchanted with Breach reduce the effectiveness of armor on the target.

• Minecraft:Wind Burst
  • Unique enchantment which can only be found in Minecraft:ominous vaults.

  • Maces enchanted with Wind Burst emit a burst of wind upon hitting an enemy, launching the attacker upward and enabling the linking of smash attacks one after the other.
  • Each level bounces the attacker higher up in the air; however any level above the default maximum of 3 obtained through commands makes the player simply lose all downward momentum and begin falling again, without gaining any upward momentum.

Command format

Entity sub-predicates

• Added raider sub entity predicate.
  • New sub-predicate has been added to match raidersFields:
    • has_raid - Match whether the raider is in an active raid.
    • is_captain - Match whether the raider is a captain.

Item stack components

• Non-default components on item stacks containing block items are now stored on block entities when placed.
• Component removals from defaults are currently not preserved.
• Placing and breaking non-block entity blocks remains unchanged - nothing is preserved.
• Does not automatically cause preserved components to be restored on drops - this requires addition of copy_components function to loot table.
• Components are stored in field called components.
  • Some components (like custom_name) are still handled by legacy serialization, which means they might not be present in there.
  • Contains map of component id to component value.

  • Removed field components and replaced it with:
    • include - optional list of data components to be copied from source.
      • If omitted, all components present are included.

General

Chat

• Client chat state (on-screen messages and chat input history) is now preserved by client when entering and exiting configuration phase.

Protocol

• The minecraft:chat_command_signed packet has been split from minecraft:chat_command.

• A more powerful active phase of the Minecraft:trial spawner with unique challenges and rewards.
  • Provides a more challenging experience that advanced players can opt into for better rewards.
• A trial spawner becomes ominous when it detects a Minecraft:player with the Minecraft:Trial Omen effect if:
  • Either it is not in cooldown.
  • Or, it is in cooldown but was not ominous during its last activation. This bypasses the cooldown.
• While active, it:
  • Glows blue instead of orange.
  • Emits soul flames instead of normal flames.
  • Spawns mobs, usually with equipment if they can wear it.
    • The Minecraft:armor these mobs wear have Minecraft:armor trims applied from the Minecraft:trial chambers.
    • Known issue: these mobs can currently drop their equipment on death, but they will not in the future.
  • Periodically spawns potions and projectiles on top of unsuspecting players and mobs.
    • Based on their location, spawners in an area select a random set of projectiles to spawn.
    • These projectiles always include a single type of Minecraft:lingering potion from a set of possible status effects.
• Becoming ominous despawns any existing mobs it spawned and resets its challenge.
  • It stays ominous until it has been defeated and its cooldown has finished.
• When defeated, it ejects a different set of loot to normal trial spawners.
• An Minecraft:ominous trial key has a 30% chance of ejecting from a defeated ominous trial spawner, replacing the usual 50% chance to eject a Minecraft:trial key.

• 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 transforms into a Raid Omen variant with a duration of 30 seconds.
