Loot fountains

Trial spawners and chests will dispense considerably more items (increased with luck), making them look like loot fountains!

More loot:

All chests, barrels, spawners and trial chests will have more items inside them
Increased loot variety (including iron, gold and copper ingots, blocks related to the trial chambers, rare items, etc)
Luck effect increases loot from all sources

Some of the loot:

Good equipments and tools are rare, but they exist
Small (very small) chance of getting mending books, so you don't need to interact with those pesky villagers (tell me if I should boost the chances for mending)
XP bottles! They aren't really OP and, unless you get super lucky, you'll just find a couple
Bucket of axolotl (I put it there because I can, but it's super rare)
Milk buckets (rare, but you can get rid of annoying effects now)
Wind Burst books are quite rare. If you think I should boost the chances for them to drop, please let me know!

"I didn't find XYZ drop":

Unless I messed up big time, every major drop from the trials should be there (discs, templates, books and core). Unless you opened the files and saw that I actually forgot something, please avoid commenting about them, as you could just be unlucky (some are rare even in vanilla).

Suggestion:

Use the Revault mod by EMD123 (available on Modrynth) together with this mod for balanced renewable vaults and a better experience :)

IF (AND ONLY IF) you know what you are doing, you can edit and tweak the datapack as much as you want, to suit your prefered Trial Chambers experience and needs :)

In case you want to edit it, some stuff you need to know:
"Weight": The chance of stuff appearing (1 = super rare | 100 = super extremely common)
"Rolls": The number of items that will appear from a chest, spawner, etc
"Bonus Rolls": Number of extra items that you get if you have the Luck potion effect
If you really want to change everything, there's a pretty good page on the Minecraft Wiki about this
