Additions

Blocks

File:Trial Spawner JE1 BE1.png Minecraft:Trial spawner

• A block similar to Minecraft:monster spawners that ejects rewards upon completion and can have variable levels of challenge in multiplayer.
• The challenge level increases for each new player a trial spawner notices nearby.
  • Challenge level doesn't decrease until it is reset during a trial spawner's cooldown.
• Unlike normal spawners, a trial spawner spawns a limited number of mobs proportional to its current challenge level.
  • It can only spawn a mob at positions that are within line of sight.
  • It can spawn a mob regardless of any light level requirement the mob has.
  • Spawned mobs are persistent and don't despawn.
• Once all mobs are defeated, the trial spawner ejects a set of rewards proportional to the current challenge level.
  • After the rewards have been ejected, the trial spawner goes into cooldown for 30 minutes during which it no longer spawns mobs.
• Can't be crafted nor obtained by players in Survival - instead, they can be found naturally placed throughout Minecraft:trial chambers.
• Extremely slow to mine and resistant to explosions, and don't drop even with Minecraft:Silk Touch.
• When placed in Creative, trial spawners have no mob type set by default.
  • The mob type can be set by interacting with it while holding a spawn egg.
• Creative and Spectator players cannot be detected or noticed by trial spawners.

Items

Minecraft:Spawn eggs

• File:Breeze Spawn Egg JE1 BE1.png Minecraft:Breeze spawn egg

File:Trial Key JE1 BE1.png Minecraft:Trial key

• An item that can only be obtained from trial spawners.
• Currently doesn't have any functionality.

Mobs

File:Breeze JE1.png Minecraft:Breeze

• The breeze is a cunning, hostile mob that can spawn via trial spawner in some rooms within the trial chambers.
• Has Template:Hp health points.
• Cannot be hit by Minecraft:arrows or Minecraft:tridents.
• The breeze moves primarily by leaping around the target, sometimes jumping quite long distances.
• An aggressive adversary, the breeze shoots volatile wind energy in the form of wind charge projectiles at its target.
• Wind charges deal a small amount of damage when colliding directly with an entity.
• After colliding with an entity or a block, wind charge projectiles produce a wind burst, which knocks back entities in the area by several blocks.
• Wind bursts also have the effect of 'activating' certain blocks:
  • Non-iron doors and trapdoors are flipped.
  • Fence gates are flipped.
  • Buttons are pressed.
  • Levers are flipped.
  • Bells are rung and swung.
  • Lit candles (both standalone and on cake) are extinguished.
• Wind bursts do not have any effect on iron doors, iron trapdoors, or any block being held in its position by a redstone signal.
• Currently does not drop any loot.

Non-mob entities

File:Wind Charge JE1 BE1.png Minecraft:Wind charge

• Fired by the Minecraft:breeze.
• Explodes upon impact, emitting a large burst of plume particles and knocking entities back similar to a TNT explosion.
• Its explosion interacts with certain blocks, including Minecraft:buttons and Minecraft:trapdoors.
• Deals damage when colliding directly with a player or mob.
• Can be deflected, just like Minecraft:fireballs.

World generation

Template:EnvLink

• A new structure in the Overworld where players can explore and take on combat challenges during the mid-game.
  • Made out of a variety of copper and tuff blocks and can be found in different sizes from large to small.
  • Relatively common throughout the deepslate layer of the underground, with the starting piece generating at a height between -40 and -20.
• The layout of each trial chamber is procedurally generated, and can include traps, supply and reward chests, decorated pots, and a variety of combat spaces.
  • Traps include dispensers containing different potential items, such as Minecraft:arrows or Minecraft:fire charges.
  • Supply chests can be found between the different rooms, and give the player blocks and items which help them navigate their trials.
  • Reward chests are guarded by challenges in each room, and can be a source of many high level enchanted books and equipment.
  • Decorated pots found in hallways can contain supplies such as iron or arrows. Some pots are decorated and others are blank.
  • The loot found in reward chests and decorated pots are still being iterated, and are absolutely not final as well as the loot from defeating mobs from a trial spawner.
• Each trial chamber can include trial spawners from three categories:
  • Melee: zombie, husk or slime.
  • Small melee: spider, cave spider, baby zombie or silverfish.
  • Ranged: skeleton, stray, or skeleton with arrows of Poison.
• Each trial spawner category only uses one mob for the entire structure when generated, and these mobs are randomized for each trial chamber.
  • For example, one trial chamber might only spawn zombies, cave spiders and strays, while another might only spawn slimes, silverfish and skeletons.
  • The exceptions to this are some trial spawners in unique rooms which always spawn breezes.
• Regular mob spawning does not happen inside the bounding boxes of the trial chamber pieces.

Trivia

• This snapshot is one of only three snapshots for Template:JE to have its digits consecutively increasing by one. The only other snapshots to have this property are 12w34a and 12w34b. As there can only be 53 weeks in a year, and because the snapshot format changed beginning with 26.1 Snapshot 1, this is also the final one.
