Not Enough Trials is a datapack or mod that completely revamps the trial chambers. The goal is to add more content, mechanics and variety while refining the difficulty and rewards to be more consistent.

Redesigned chambers
5 new original chambers
Huge mob variety
Restructured and rebalanced loot
Boss chambers
Secret chambers
Vertical trial chambers Variant
4 new rare enchantments

General Changes

Rooms are generally more open to get rid of the maze-like traversal of the original
Every chamber generates consistently instead of constantly colliding into eachother, ending hallways with just dead ends
Wind charge usage is more encouraged, from activating out of reach buttons to more efficiently opening groups of trapdoors
Dispensers are way more powerful so that you can strategically use them against enemies
Every block of chiseled copper activates something when scraped, so scrape every one you see!
Luck potions will be rewarded after completing non-combat challenges in secret rooms, and its effect increases vault loot
The structure no longer forces itself to be covered in blocks, so you can find a trial chambers easier while mining
Each chamber will always have exactly 4 spawners (gives more consistency to the amount of keys you get per structure)
Trial Chambers are now exposed in caves so you can find them without needing a map

Loot

Base vaults are split into three: armor, valuables, and weapons. This will let you (partially) customize your loot and opt out of stuff you don't want. All 3 vault types will always be found grouped together. The structure will generate plenty of these incase a player wants to use all of their keys on only one category. Luck adds a 33% chance to dispense double the loot. Aesthetic based loot (sherds, banner patterns, trims) are moved to hidden chests in intersections so that they don't get in the way of the more useful vault loot.

Armor table

One of:
35% - Piece of iron armor (any enchants except for frost walker, swift sneak, soul speed and mending)
20% - Armor book (protection, feather falling, respiration, thorns, depth strider, aqua affinity)
20% - Shield (unbreaking 1-3, half chance of mending)
13% - Piece of diamond armor (same as iron)
6% - Turtle helmet (unbreaking 1-3)
6% - Turtle master potion

Valuables table

One of:
33% - 6-8 Emeralds
33% - 6-8 Iron ingots
13% - 2-4 Diamonds
13% - Random book (any enchants, levels 13-18)
8% - Golden apple

Weapons table

One of:
30% - 8-12 Spectral arrows
30% - 8-12 Tipped arrows (slowness, weakness, long poison)
10% - Iron axe (sharpness 1-3, unbreaking 1-3)
9% - Bow (unbreaking, punch, power)
9% - Crossbow (unbreaking, quick charge, piercing)
4% - Diamond axe (sharpness 1-2, unbreaking 0-2)
4% - Trident book (impaling, loyalty, riptide)
4% - Sword book (sharpness, fire aspect, knockback, sweeping edge)

Ominous vaults are still a single category. You will get both types of keys from ominous spawners so the ominous vaults will act as an enhancement to the loot the other vaults give you.

Ominous table

One of:
100% - 4-12 Wind charges

One of:
33% - Ominous bottle (level 1-3)

One of (if player has luck effect):
40% - Luck potion

One of:
13% - Iron block
13% - Emerald block
11% - Diamond axe (sharpness 1-4, unbreaking 1-3)
11% - Piece of diamond armor (same enchants from armor table, but higher levels)
10% - Bow (any enchants levels 20-25)
10% - Crossbow (any enchants levels 20-25)
10% - 4-12 Tipped arrow (Harming 2)
6% - Mace book (breach 1-3 with wind burst 1 or density 1-3 with wind burst 1)
6% - Rare enchant book (too many to list)
6% - Mending book
4% - Enchanted golden apple

One of:
22% - 6-8 Iron ingots
22% - 6-8 Emeralds
14% - 4-12 Tipped arrows (slowness 2)
13% - Golden apple
13% - Common enchant book (sharpness, protection, efficiency, power, piercing, unbreaking)
8% - 6-8 Diamonds
8% - 1-3 Ender pearls

One of (if player has luck effect):
25% - Special trial chambers enchantment book (daredevil, storm front, equity or razor tip)

Pots can hold wind charges or less valuable ores, such as lapis, copper and redstone. You'd likely find this structure while mining, so this is meant to synergize with that.

Tridents and heavy cores are reserved for bosses. Once defeated, the main boss spawner will dispense a trident on normal difficulty or a heavy core on ominous. This gives you a 100% chance of getting these items per trial chamber (unlike the very low chances per vault from vanilla) in exchange of the added difficulty from the bosses.

Food will be dropped by tough mobs instead of them filling up vault loot tables.

This is something I particularly want to balance well, so feedback would be appreciated!

Enchantments

Trial chambers contain 4 exclusive enchantments to act as another incentive for grinding vaults. All are single level, situationally powerful, and changes the behavior of the weapon sort of in the same vein as channeling or silk touch. Ominous vaults have a 25% chance of ejecting a book containing one of these but only if the player has the luck effect.

Daredevil: Creates an explosion on the opponent if hit with a mace's smash attack and deals massive damage, but also damages you depending on how close you are.

Storm Front: Causes a wind charge explosion wherever a trident is thrown. Acts as a renewable wind charge. Incompatible with riptide.

Equity: Axes mimic Flame II and Knockback II (along with a small damage increase) when attacking an entity holding a sword.

Razor Tip (1.21.11+): Spears deal 2x damage if a hit is landed right at the tip of your attack range. The bonus damage range increases if the player's attack reach also increases (including creative mode).

Bosses

There are 5 different boss chambers at the end of every trial chambers, each with unique mechanics and difficult mobs. I want most of these to stay a surprise so there won't be much detail here. Defeating a boss on normal difficulty will reward each player a trident. Ominous difficulty will reward a heavy core instead. While you always can run straight to the boss to get a trident/heavy core if you really wanted to, you'll be missing out on all the other loot the structure has.

Unlike normal chambers, you typically only need to complete the main boss spawner. Usually the other spawners are supporting the boss and sometimes spawn mobs forever.

Secrets

Without spoiling anything, here are some tips if you find yourself confused in a secret chamber:

The keys found in secret chambers can only be used on the vaults found within the same room
A sign with a number next to a vault means you need that many keys to open it
Figuring out what your goal is is part of the puzzle, but the main mechanic of the chamber is typically right in front of you as you enter the room.
