Enchantments^[3]

• Three new enchantments have been introduced that are unique to the mace.
• Breach
  • Rare enchantment, accessible in the enchanting table and on enchanted books in loot.
  • Has 4 levels.
  • Maces enchanted with Breach reduce the effectiveness of armor on the target.
    • The effectiveness of the armor is reduced by 15% per Breach level.
• Density
  • Common enchantment, accessible in the enchanting table and on enchanted books in loot.
  • Has 5 levels.
  • Maces enchanted with Density do more damage per fallen block per Density level.
    • Damage dealt per fallen block is increased by 1 per level of Density.
• Wind Burst
  • Unique enchantment which can only be found in ominous vaults.
  • Has 3 levels.
  • 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.

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

• Added item_name item stack component.
  • When present, replaces default item name with contained chat component.
  • Differences from custom_name:
    • item_name can't be changed or removed in anvil.
    • item_name is not styled with italics when displayed to player.
    • item_name does not show labels where applicable (for example: banner markers, names in item frames).

Loot tables

• Added new loot table type minecraft:equipment.
  • Has required parameters of this_entity and origin.
    • this_entity: the mob that is about to be given equipment.
    • origin: the position of the mob.
• Added optional equipment_loot_table to the spawn data present in the SpawnPotentials of monster spawners and spawn_potentials of trial spawner configs.
  • If present, rolled items from the specified loot table are equipped to the mob that spawns.

Tags

• Added minecraft:is_player_attack damage type tag: for attacks performed by the player.
• Added the #enchantable/fire_aspect, and #enchantable/sharp_weapon item tags.

Cobweb

• Added unique sounds.

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.

Loot functions

• Changed copy_components loot function.
  • 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.
    • exclude - optional list of data components to be excluded from copying.
      • If omitted, defaults to empty.
    • Only components that are included (explicitly or implicitly) but not excluded are copied.
• Changed set_name loot function.
  • Added optional field target to specify which name should be set.
  • Values:
    • custom_name - sets custom_name component (default).
    • item_name - sets item_name component.

Chat

• Client chat state (on-screen messages and chat input history) is now preserved by client when entering and exiting configuration phase.
• Message signature chain handling remains unchanged - going into configuration phase starts new session.
• If client has message delay configured, pending messages are delivered immediately before leaving world.
• Server can clear chat state by sending reset_chat packet in configuration phase.

Data pack

• The data pack version is now 37.
• Int and float providers used in worldgen definitions are no longer wrapped in an extra value field next to type
  • For example, {"type":"minecraft:uniform","value":{"min_inclusive":0.0,"max_inclusive":1.0}} becomes {"type":"minecraft:uniform","min_inclusive":0.0,"max_inclusive":1.0}.

Protocol

• The minecraft:chat_command_signed packet has been split from minecraft:chat_command.
  • Commands that do not accept any signed arguments use the unsigned packet, and don't pass any 'last seen' chat updates.

Resource pack

• The resource pack version is now 31.
• Added the following particle types: infested, item_cobweb, small_gust, raid_omen, trial_omen, trial_spawner_detection_ominous, and ominous_spawning.
• Added the following sound events: block.cobweb.break, block.cobweb.step, block.cobweb.place, block.cobweb.hit, block.cobweb.fall, block.trial_spawner.about_to_spawn_item, block.trial_spawner.spawn_item, block.trial_spawner.spawn_item_begin, block.trial_spawner.charge_activate, block.trial_spawner.ambient_charged, item.ominous_bottle.dispose, event.mob_effect.bad_omen, event.mob_effect.trial_omen, and event.mob_effect.raid_omen.

• Updated textures for normal vault block.
• Added the following mob effect icon textures: infested, oozing, weaving, wind_charged, raid_omen, trial_omen, and bad_omen_121.
• Added new models for ominous state of vault block.

Tags

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.
• A trial spawner becomes ominous when it detects a player with the 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 armor 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 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 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 ominous trial key has a 30% chance of ejecting from a defeated ominous trial spawner, replacing the usual 50% chance to eject a trial key.

• Can be found throughout the trial chambers in harder to find places.

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 transforms into a Raid Omen variant with a duration of 30 seconds.
    • Once the Raid Omen expires, a raid starts 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.

    • For entities that cannot receive the Infested effect.
  • #immune_to_oozing: contains slime.
    • For entities that cannot receive the Oozing effect.

  • #enchantable/mace: contains mace.

Trial spawner

• 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.
• The loot ejected from trial spawners has been adjusted.
  • It now has a focus on providing higher quality food more often to make replenishing between fights more safe.

Vault

• The loot found within vaults has been adjusted.
• Standard vaults 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.
  • In heavy core's place, standard vaults instead have a very rare chance of providing a trident.

Mace

• Increased the power and range of the knockback effect from a smash attack.
• Introduced an even stronger knockback when falling for more than 5 blocks before attacking.
