Trial Chambers are massive underground dungeons from the 1.21 Tricky Trials update. They're packed with spawners that spawn mob waves, nasty traps, and vaults full of god-tier loot. Think copper and tuff blocks everywhere, super deep underground around Y=-40 to Y=0. Perfect for mid-to-late game grinds. Beat spawners for keys, pop vaults for the win. Go ominous mode with Bad Omen for juiced-up fights and better drops.

How to Find Minecraft Trial Chambers

Minecraft The Breeze

  • Cartographer Maps: Level up a villager to Journeyman Cartographer. Trade 12 emeralds + compass for a Trial Explorer Map. Points right to the nearest one.
  • Chunkbase: Punch your seed into Chunkbase. One every ~2km chunks.
  • Commands: /locate structure minecraft:trial_chambers (cheats on).
  • Dig Tip: Strafe mine at Y=-53 for dia stacks on the way down. Or shaft straight to the map coords at Y=-40.

Prepare your gear

These ain't no cakewalk. Prep for hordes, poison arrows, and knockback spam.

  • Armor: Full netherite with Prot 4 or Projectile Prot. Stack 3+ totems in offhand.
  • Weapons: Sharp 5 sword/axe, Power 5 bow or crossbow with Quick Charge. Infinity if bows. Shields x16 (they break fast).
  • Pots: Strength, Regen, Swiftness extended. Milk buckets for poison/slowness.
  • Utils: Cobble stacks for pillars, torches, golden apples, ender pearls, water bucket (lava traps).
  • Squad Scaling: Mobs ramp up per player. Squad up for faster clears, but waves hit harder.
Skip Swift Sneak. Doesn't work here.
