The trial update is a major update for Minecraft, adding new decorative blocks, items, mobs, art, and more to the game. It also adds new challenges and gameplay elements, such as Trial Chambers — sprawling structures stuffed with traps and intense combat that provide exciting rewards for every player who triumphs.
Trial Chambers are procedurally generated dungeon-like buildings that feature many of the block types and layouts of other Minecraft structures, including hallways, rooms, atriums, and intersections. Each chamber contains a variety of trial spawners, vaults, and dispensers that can dispense fire charges, snowballs, arrows, splash potions, and other hazards. The challenge level of a chamber can vary depending on the biome, with stray and skeletons found in badlands providing little difficulty while the breeze and bogged — two new melee mobs that can spawn in trial chambers — provide much more difficulty.
Defeat mob waves in a series of trials and receive loot, including rare items such as the new mace. The update also introduces the breeze, a new hostile mob that attacks with wind projectiles that can send players and other entities flying, and the bogged, a swamp variant of skeleton that shears with axes and shoots poisonous arrows.
In addition to the new challenge, the trial update also features twenty new paintings by Mojang artists Sarah Boeving and Kristoffer Zetterstand. It also features new ambient tracks by Lena Raine, Kumi Tanioka, and Aaron Cherof. The update will be available to all players on Java Edition and Bedrock Edition, releasing June 13.
