Old world, or you want to pick the chambers yourself?
Auto-discovery is off by default on purpose, because on established worlds, player-built stuff made of tuff and copper, which in rare cases the plugin mistakes for a trial chamber.
Select it with WorldEdit instead:
//wand
/trial generate wand MyChamber
/trial snapshot create MyChamber
Same features either way. Docs →
What it does
Loot
- Every player gets their own vault loot
- Chests, barrels, droppers and pots too, if you want
- Or make it a race: first player claims the vault, it stays shut for everyone else
- Build your own loot tables. By weight, or by plain % chance
- Different loot per chamber
- Edit it all in a menu. No YAML (optional)
Resets
- Chambers restore on a timer you set
- Players get a warning first
- Set it to
0to only reset by hand
Protection
- Nobody breaks blocks or spawners inside a chamber
- Optional: let players tunnel in through the wall. They get no drops, the wall heals on reset
Custom chambers (optional)
- Use a datapack, such as Crazy Chambers
- Or make rooms yourself, the plugin stitches them into a new chamber
During a fight
- Boss bar shows wave progress
- Spawner mobs stop killing each other
- Leftover spawners glow so nobody hunts for the last one
- Dead players can spectate their team
After completion
- Statistics; Vaults opened, mobs killed, chambers cleared, time spent
- Leaderboards
- 30+ PlaceholderAPI placeholders
Under the hood
- Paper, Purpur, Pufferfish and Folia
- Won't lag your server! Big chambers load in small pieces (smooth even with only 4GB ram)
- SQLite or MySQL
- Every message is editable in one file (fully translatable)
- Config updates itself, keeping your settings.

Want more?
This plugin stays free. Three paid add-ons, if you want them — esmp.fun/plugins:
- Mythic Trials — chambers get harder every time a player clears them -> 25 difficulty tiers with custom tweaked smarter vanilla MobAI, better rewards and optional seasons
- Wild Spawners — (custom-mob) trial spawners, anywhere on the map and/or in your shops
- Vault Crates — crates that use real Trial Vaults instead of chests (no resource packs!)
