TrialChamberPro

What's new in 1.5.0

• Fixed: vaults handing out vanilla loot instead of your tables. On servers with 100+ chambers the chamber cache was evicting older ones, so their vaults quietly fell back to vanilla trial loot and ignored your loot-table edits. The cache now keeps every registered chamber — the fix also repairs spawner-wave tracking and tier scaling on large servers.
• Faithful loot + bulk drag-in editor. Loot items now keep their enchantments, potion effects, custom names and NBT, and a new Bulk add button lets you drag/shift-click a whole chest of items in at once.
• Procedural dungeon generation. Build modular rooms with minecraft:jigsaw-block doorways, then /tcp dungeon generate stitches them together (with rotation) into a brand-new chamber that resets, loots and scales like any other.
• Hardened resets. No more StandaloneCoroutine was cancelled errors or has no detected players console spam; resets are throttled/staggered so a wave of due chambers can't tank TPS; evicted players are never teleported into a wall; optional operator-confirm queue and FastAsyncWorldEdit placement.
• New ChamberClearedEvent for plugin developers — fires once when a registered chamber is cleared in one continuous run, carrying the chamber, the cumulative set of participating players, and the run duration. Built for progression plugins, achievements and leaderboards.

Plus everything from the 1.4.x line: per-chamber reset broadcast toggle (1.4.7), Folia/Luminol teleport crash fixes (1.4.6), Silk Touch recovery for preset spawners (1.4.5), vanilla-accurate bundled loot tables (1.4.4), chamber pause state (1.4.3), MiniMessage everywhere, smarter auto-discovery, a flatter admin GUI, and trial spawner wave tracking fixes. And from 1.3.x: custom mobs (MythicMobs, EliteMobs, EcoMobs, LevelledMobs, InfernalMobs, Citizens), fully translatable GUI (~330 gui.* keys), Bukkit events API, spawner presets, /tcp give, and Minecraft 26.x support via the -mc26 build.

Premium Add-on Modules

TrialChamberPro is, and always will be, completely free. But after a lot of requests from server owners wanting to push things further, we now offer optional premium modules for servers that need more.

🔷 TCP-WildSpawners

Place TCP preset spawners anywhere on your survival map — no Trial Chamber required. Hand them out via shops, crates, or staff commands. Wherever a player puts one down, it summons your custom mobs. Includes an in-game GUI editor, per-preset griefing protection, holograms, mob tether, creative pick-block, and state-preserving mining so players can relocate a live spawner without losing cooldown progress.

Requires TrialChamberPro v1.4.0+ (free).

🔶 TCP-VaultCrates

The first crate plugin that doesn't use chests. Vanilla Trial Vaults are the only Minecraft block with built-in per-player loot state, two visual tiers (normal + ominous), a key mechanic, and a dramatic open animation that doesn't need a resource pack. TCP-VaultCrates lets you register vaults anywhere on your map as crates with configurable loot pools and per-tier keys. Hand keys out via shops, missions, or — when paired with TCP-WildSpawners — drop them from spawner mobs.

Requires TrialChamberPro v1.4.0+ (free).

The definitive Trial Chamber management plugin for multiplayer servers.

Transform Minecraft's Trial Chambers from single-use dungeons into renewable, multiplayer-ready content. Automatic resets, per-player loot, custom rewards, griefing protection — and it all works out of the box.

Why TrialChamberPro?

Vanilla Trial Chambers weren't designed for multiplayer. The first player takes everything, vaults stay locked forever, and griefers destroy spawners. TrialChamberPro fixes all of that.

Problem	Solution
First player gets all loot	Per-player vault system with individual cooldowns
No way to reset chambers	Automatic scheduled resets with player warnings
Griefers break spawners	Full protection system with optional WorldGuard support
Paper trial key bugs	Built-in fixes for known Paper issues
No progression tracking	Statistics, leaderboards, and PlaceholderAPI support
Setup overhead per chamber	Auto-discovery — chambers register themselves

---

Two-Line Plug-and-Play Setup

For most servers, the only thing you need to configure is this:

# plugins/TrialChamberPro/config.yml
discovery:
  enabled: true        # find natural trial chambers automatically
  auto-snapshot: true  # capture blocks so resets can restore them

Restart once. Fly or walk through your world — every natural trial chamber registers itself as its chunks load, with per-player loot, protection, and automatic resets already active. Done.

Why it's opt-in: on old worlds that pre-date 1.21, players sometimes build decorative structures out of tuff and copper blocks. The auto-detector could register those as chambers. On fresh worlds there's no risk. More detail in the docs →

Prefer manual control? You can still register chambers with WorldEdit (/tcp generate wand MyChamber) or by coordinates — see Your First Chamber.

Features

Core Systems

• Auto-Discovery — natural chambers register themselves on chunk load + startup sweep. Docs →
• Automatic Resets — chambers restore on schedule with configurable warnings, or set interval to 0 for manual-only.
• Per-Player Vaults — everyone gets their own loot with separate cooldowns.
• Full Protection — block break/place, container access, mob griefing prevention. WorldGuard-aware.
• Statistics & Leaderboards — vaults opened, mobs killed, time spent. Docs →
• Admin GUI — /tcp menu does everything. No YAML editing required.

Advanced Loot

• Multi-Pool Tables — common / rare / unique pools like vanilla, fully configurable. Docs →
• Per-Chamber Overrides — assign a different loot table to any specific chamber.
• GUI Editing (new in 1.2.26) — open /tcp menu → Loot Tables, click a table, and edit it. Changes save to loot.yml instantly.
• Custom Plugin Items — drop Nexo, ItemsAdder, or Oraxen items directly from vaults:

  - type: CUSTOM_ITEM
    plugin: nexo        # or itemsadder / oraxen / craftengine / mythiccrucible
    item-id: mythic_sword
    weight: 5
  

• Custom Model Data — set custom-model-data on any vanilla item for resource-pack integration.
• Command Rewards — run any console command as loot (economy deposits, permission grants, XP).
• Potion & Tipped Arrows — full attribute support including Bad Omen III–V ominous bottles.
• LUCK Integration — optional bonus rolls for players with the LUCK effect.

Multiplayer Enhancements

• Spawner Wave Tracking — boss bar shows wave progress as players fight. Hysteresis-based despawn means the bar disappears when you leave the area (improved in 1.2.26).
• Spectator Mode — dead players can watch teammates complete the challenge, bounded to the chamber.
• PlaceholderAPI — 20+ placeholders for scoreboards, holograms, tab lists.

Technical Excellence

• Folia Native — full support for regionized multithreading.
• Paper / Purpur / Pufferfish — works on all major Paper forks.
• Async Architecture — Kotlin coroutines, zero main-thread blocking.
• Dual Database — SQLite (default) or MySQL with connection pooling.
• WorldEdit / FAWE — optional, used only if you want selection-based chamber creation.

Fully Translatable

Every user-facing string lives in plugins/TrialChamberPro/messages.yml. Want your server in French, Chinese, Spanish, or Klingon? Edit one file, /tcp reload, done.

Supports &-style color codes, {placeholder} substitution, and Adventure Components for boss bars.

Quick Start (manual mode)

Prefer not to use auto-discovery? Classic workflow still works:

1. Drop the JAR in your plugins folder
2. Start your server
3. Select a Trial Chamber with WorldEdit (//wand)
4. Run: /tcp generate wand MyChamber
5. Run: /tcp snapshot create MyChamber   (enables auto-reset)
6. Done!

Commands (at a glance)

Command	Description
/tcp menu	Open the admin GUI (does everything)
/tcp generate wand <name>	Register chamber from WorldEdit selection
/tcp reset <chamber>	Force immediate reset
/tcp snapshot create <chamber>	Enable automatic resets
/tcp loot set <chamber> <normal|ominous> <table>	Override loot for a chamber
/tcp stats [player]	View statistics
/tcp leaderboard <type>	View top players
/tcp reload	Reload config & loot tables

Permissions (essentials)

Permission	Description	Default
tcp.admin	Full admin access	OP
tcp.stats · tcp.leaderboard	View own stats / leaderboards	Everyone
tcp.spectate	Use spectator mode after death	Everyone
tcp.bypass.cooldown	Ignore vault cooldowns (careful: removes progression!)	OP
tcp.bypass.protection	Build in protected chambers	OP
tcp.discovery.notify	Get notified when auto-discovery registers a chamber	OP

Heads up: tcp.bypass.cooldown is granted to OPs by default. If you're testing cooldowns as an OP, they'll appear broken — either test as a non-OP or explicitly negate the permission.

Essential Configuration

Sensible defaults work out of the box. The three settings most servers actually tweak:

global:
  default-reset-interval: 172800   # 48 hours. Use 0 for manual-only resets.

vaults:
  normal-cooldown-hours: -1        # -1 = vanilla (locked until chamber reset)
  ominous-cooldown-hours: -1       # Set a positive number for per-player time cooldown.

discovery:
  enabled: true                    # Auto-register natural chambers. Opt-in.
  auto-snapshot: true              # Allow auto-discovered chambers to restore on reset.
