World Generation
Trial Chambers
Trial Chambers are underground Copper-and-Tuff structures built around repeatable combat encounters. Their rooms combine traps, supplies, varied terrain, and Trial Spawners, supporting both solo expeditions and groups.
Combat and Rewards
Trial Spawners and Vaults
Trial Spawners adjust encounters to nearby players and enter a cooldown after a completed trial. Vaults use Trial Keys and allow each player to claim their own reward rather than sharing one ordinary chest’s contents.
Ominous Trials
An Ominous Bottle provides Bad Omen. Entering a Trial Spawner’s area with the relevant omen turns the encounter into an Ominous Trial, with tougher conditions and access to Ominous rewards. This system also changed how players initiate Raids.
Mace and Wind Charges
Mace
The Mace combines a Heavy Core from Ominous Vault loot with a Breeze Rod. Its smash attack rewards falling onto a target, supported by Density, Breach, and Wind Burst enchantments.
Wind Charges provide knockback for combat, movement, and interactions with selected blocks.
Mobs
Breezes move around Trial Chambers and fire Wind Charges that push players and activate mechanisms. Bogged are poisonous-arrow Skeleton variants found in swamps and suitable Trial encounters; Shears can harvest the Mushrooms on their heads.
Blocks and Automation
Crafter
The 
Crafter automates crafting with a redstone signal. Individual slots can be disabled to control the recipe layout, allowing transport systems and redstone to supply ingredients and collect results.
Copper and Tuff
Expanded sets include Copper Bulbs, Grates, Doors, Trapdoors, and Chiseled Copper, alongside Tuff Bricks, polished forms, Stairs, Slabs, and Walls. Copper oxidation changes the lighting behavior of Copper Bulbs.
Other Highlights
New Armor Trims, Banner Patterns, Pottery Sherds, Paintings, and Music Discs extended the update beyond combat. The new effects Wind Charged, Weaving, Oozing, and Infested provide additional interactions through Potions and Ominous Trials.
