Tweaked Trials Mod (1.21.1, 1.21) introduces several quality-of-life improvements to the newly added Trial Chambers in Minecraft 1.21. One of the most frustrating mechanics in vanilla is the permanent lockout on trial vaults once opened, they can’t be used again. This mod changes that behavior by allowing vaults to be reopened after a configurable cooldown, making repeated runs and multiplayer gameplay significantly more enjoyable.
Beyond that, the mod also helps players visually locate the trial spawner by adding particle effects to spawned mobs. This makes navigating and clearing chambers faster, especially when multiple players are exploring at once or if the chamber layout is particularly complex.

Features:
- Trial vaults can now be reopened after a user-defined cooldown period
- Adds glowing particle effects to mobs that spawn from trial spawners
- Helps players identify the trial spawner by following particles
- Greatly improves multiplayer replayability of trial chambers
- Fully configurable via server/data pack settings
- Keeps core trial chamber mechanics intact while improving usability
- Compatible with Fabric mod loader

Why Use Tweaked Trials Mod?
Minecraft 1.21’s trial chambers are a fun new addition, but their one-time vault usage can make them feel static, especially in long-term multiplayer worlds. Tweaked Trials fixes that by allowing you to reuse chambers over time. With added particle trails that visually mark trial spawner activity, the mod also reduces confusion during raids and enhances your sense of direction in large structures. Whether you’re designing an adventure map or running a public SMP, this mod makes trial chambers more dynamic and player-friendly.
FAQs
Can I set my own cooldown time for vaults?
Yes. The cooldown duration is fully configurable so you can tailor it to your server’s pacing or personal preference.
Do vaults reopen automatically?
Yes. Once the cooldown expires, players can reopen the vault normally without any additional setup.
Are these features client-side or server-side?
The mod requires installation on the server to enable vault cooldowns and particle functionality. Clients may also need it for visual effects.
Will this work in singleplayer?
Yes. All features function in both singleplayer and multiplayer environments.
Is this compatible with other 1.21 structure mods?
Yes. Since it only modifies behavior inside trial chambers, it should not conflict with other structure or worldgen mods.
