Revamping the Trial Chambers with the Not Enough Trials Datapack
Trial chambers arrived in Minecraft 1.21 as a fresh combat challenge, but many players felt they lacked variety and consistent rewards. The Not Enough Trials datapack (also available as a mod for Forge, Fabric, and NeoForge) completely overhauls these structures, injecting them with new mechanics, redesigned rooms, and a loot system that respects your time. Whether you are a seasoned adventurer or a builder hunting for rare tridents, this expansion transforms trial chambers into a must-visit destination.
Redesigned Core Mechanics and World Generation
One of the first things you will notice is how much more open the chambers feel. Gone are the cramped, maze-like corridors that often dead-ended into nothing. Every chamber now generates consistently, eliminating collisions and awkward hallway terminations. The structure is no longer fully encased in blocks, making it easier to spot while caving or mining—trial chambers are now exposed in caves, so you can stumble upon them without a treasure map.
Wind charges play a much larger role. You can activate out-of-reach buttons, efficiently open groups of trapdoors, and even use them to expand hanging platforms in certain chambers. Dispensers scattered throughout are significantly more powerful, allowing you to strategically turn them against mobs. Every block of chiseled copper activates something when scraped, so keep your axe handy and scrape every piece you see. Luck potions, earned from secret non-combat challenges, increase vault loot and become a key resource for maximizing your haul.
Each chamber now contains exactly four spawners, giving you a predictable number of keys per structure. Spawners can feature zombie variants, skeleton variants, spiders, slimes, pillagers, and more. Tough spawners introduce mini-boss-like encounters that drop food, keeping you sustained without clogging vault loot tables.
New and Redesigned Chambers
The datapack introduces five brand-new chambers alongside revamped classics. Here is a quick tour of what you will face:
Classic Chambers, Reimagined
- Corridors – Pots, vaults, and chamber doors line the walls, with arrow and fire charge dispensers that can be aimed at spawners. Dripstone on the floor punishes careless falls.
- Ledge – Platforms sit lower, with skeleton variants as normal spawners and jockeys as the tough spawner.
- Chasm – A powder snow pit dominates the center, with holes and trapdoors to drop mobs. Normal spawners include zombie variants, spiders, and zoglins; the tough spawner unleashes big slimes.
- Cubic – A randomly generated layout featuring zombie variants, zoglins, slimes, and wither skeletons.
- Crawl – Mostly unchanged but now includes wind charge launchers to fling you to the next floor.
- Eruption – Press all four buttons to guide lava from the center. Fight vindicators, slimes, pillagers, and breezes.
- Pedestal – Cross a gap using trapdoors and extending platforms while slimes, pillagers, and phantoms harass you. Witches act as the tough spawner—honey bottles cure poison.
- Assembly – A breeze guards the bottom; climb a parkour section to fight ranged mobs on hanging platforms. Wind charges can expand those platforms, and deadly rocket dispensers keep you moving.
- Slanted – Split into corner mini-chambers designed for specific mob types, with a more maze-like layout. Vexes serve as the tough spawner.
Five Original Chambers
- Ladder – Ascend a tower of platforms, each with a spawner, while blazes rain fire from above. Use chiseled copper to create staircases and knock mobs onto dripstone.
- Channel – A water-themed room where soul sand launches mobs above the surface. Drowned and trident drowned swarm, with guardians as the tough spawner.
- Crash – Explosive chaos defines this chamber. Creepers and zombies fill the floor, while ghasts shoot from fixed positions. The terrain itself is trapped to punish reckless explosions.
- Cargo – Ride shifting rails alongside mobs. Activate a secret to reach the top rails and face rocket pillagers as the tough spawner.
- Streak (1.21.4+) – Speed potions and soul speed help you evade fast melee skeletons. Avoid tripwires that release the tough spawner: creakings.
For players who enjoy tinkering with mods, the Not Enough Trials datapack can be effortlessly added through the foxygame.net launcher—a flexible, modern tool that lets you browse and install mods directly from its menu, saving you the hassle of manual file management.
Loot System: Vaults, Keys, and Customization
Base vaults are now split into three categories: armor, valuables, and weapons. All three always generate together, letting you spend keys on exactly what you need. Luck grants a 33% chance for double loot. Aesthetic items like sherds, banner patterns, and trims have been moved to hidden chests in intersections, so they never clutter your vault rewards.
The armor table offers iron and diamond pieces, shields, armor books, and even turtle helmets. The valuables table provides emeralds, iron, diamonds, enchanted books, and golden apples. The weapons table delivers spectral and tipped arrows, enchanted axes, bows, crossbows, and trident or sword books.
Ominous vaults remain a single category but act as an enhancement. You always get wind charges and an ominous bottle, plus a chance at iron blocks, emerald blocks, high-level diamond gear, mace books, rare enchantments, mending, or even enchanted golden apples. Luck adds a 25% chance for one of the four exclusive trial chamber enchantments.
Pots scattered around hold wind charges or less valuable ores like lapis, copper, and redstone—perfect for the mining-focused adventurer. Tridents and heavy cores are reserved for bosses, guaranteeing a 100% drop per chamber instead of the vanilla lottery.
Exclusive Enchantments
Four single-level enchantments change how your weapons behave, offering powerful situational effects:
- Daredevil – Mace smash attacks create an explosion that deals massive damage but also hurts you based on proximity.
- Storm Front – Trident throws trigger a wind charge explosion, giving you a renewable wind charge source. Incompatible with Riptide.
- Equity – Axes mimic Flame II and Knockback II (plus a small damage boost) when hitting an entity holding a sword.
- Razor Tip (1.21.11+) – Spears deal double damage if you land a hit at the very tip of your attack range. The bonus range scales with attack reach, including creative mode.
Boss Chambers and Secrets
At the end of every trial chambers lies one of five boss chambers, each with unique mechanics and punishing mobs. Defeating the main boss spawner on normal difficulty rewards every player with a trident; on ominous difficulty, you get a heavy core. While you can rush straight to the boss, you would miss out on the rest of the structure’s loot. Supporting spawners often spawn mobs indefinitely, so you must stay focused.
Secret chambers hide puzzles that reward keys for vaults within the same room. A sign with a number next to a vault tells you how many keys are needed. The main mechanic is usually visible right as you enter, so keep your eyes open. These non-combat challenges also grant luck potions, further boosting your ominous vault rolls.
Why Not Enough Trials Deserves a Spot in Your World
This datapack fixes the trial chamber’s biggest flaws: repetitive layouts, uneven rewards, and a lack of meaningful choice. By restructuring rooms, adding verticality, and tying powerful items to boss fights, it makes every run feel purposeful. The enchantments alone give you a reason to grind vaults, and the revamped loot tables let you target specific gear without frustration. Whether you are playing on a vanilla server or a modded instance, Not Enough Trials breathes new life into the underground combat loop. Install it, grab your wind charges, and prepare for the ultimate adventure.
