Just Trial Spawners
If you have been longing for the thrill of Minecraft 1.21's Trial Chambers but prefer the stability and mod ecosystem of version 1.20.1, your wait is over. Just Trial Spawners is a full-featured Forge backport that transplants the entire Trial Spawner and Vault system, complete with the Breeze, Bogged, wind charges, ominous mode, and all trial-themed enchantments, directly into your 1.20.1 world. This isn't a stripped-down imitation; it is a production-ready, faithful recreation designed with modpack makers in mind.
Why Choose Just Trial Spawners for Minecraft?
There are a few backports out there, but Just Trial Spawners for Minecraft stands apart because it focuses on being a complete package. It does not add any world generation, which means you have total control over where and how these mechanics appear. This makes it an incredibly powerful tool for map makers and modpack creators who want to integrate trial-style challenges into their custom adventures without relying on the vanilla 1.21 structure generation.
The core philosophy here is "faithful behavior." The developer has meticulously recreated the full state machine of the Trial Spawner, ensuring that every mechanic, from player detection to reward ejection, works exactly as it does in the newer version. This includes the intricate per-player scaling for mob waves, the ominous item spawner system, and the transformation into ominous mode when a player with Bad Omen approaches.
Core Features: The Trial Spawner and Vault
The heart of this add-on is, of course, the Trial Spawner itself. It is not just a block that spawns mobs; it is a complete system. You can right-click it with a spawn egg to set the next mob type, and a custom item renderer will show a spinning preview of that mob in your hand and in GUIs. A tooltip conveniently displays the currently configured mob, making setup intuitive.
Vault Mechanics
The Vault is equally well-implemented. It requires a Trial Key or Ominous Trial Key to open and features per-player reward tracking, ensuring each player gets exactly one reward per vault. The ominous vault variant offers upgraded loot for those brave enough to trigger it. The team even ensured proper cutout rendering for transparent textures, so the Vault looks crisp and correct.
New Mobs and Combat Mechanics
No trial is complete without its adversaries. The Breeze is a faithful recreation with authentic 1.21 AI, including long jumps, slides, wind charge shooting, and even stuck detection. The Bogged, a skeleton variant, shoots poison arrows and can be sheared for mushrooms via a datapack-configurable loot table. Both come with their own spawn eggs.
Wind Charges and Projectiles
The Wind Charge and Breeze Wind Charge projectiles have authentic 1.21 knockback physics, including eye-height direction vectors and line-of-sight falloff. The throwable Wind Charge item creates a wind burst explosion that can trigger redstone components like buttons, levers, trapdoors, doors, and fence gates, adding a new layer of puzzle potential to your builds.
Enchantments, Effects, and Creative Tools
The add-on brings the full suite of trial-themed enchantments to 1.20.1. Density (I-V) adds +1 damage per level and is incompatible with Sharpness, Smite, and Bane of Arthropods. Breach (I-IV) bypasses armor effectiveness via a damage multiplier. The treasure-only Wind Burst (I-III) triggers a wind burst explosion on hit. All the new mob effects—Trial Omen, Wind Charged, Weaving, Oozing, and Infested—are included with custom textures.
For creators, the Just Trial Spawners creative tab is a goldmine. It includes pre-configured trial spawners for 36+ hostile mobs, ranging from zombies and skeletons to wardens and the new breeze and bogged. You also get all five amplifier variants of the Ominous Bottle. Admin-only commands like /trialspawner edit and /trialspawner give allow for precise configuration, making it a breeze to set up complex encounters.
Configuration and Compatibility
Server-side configuration is handled through config/justtrialspawners-server.toml. You can adjust the cooldown ticks, player detection range, mob spawn range, and toggle ominous mode. There is also a knockback multiplier for wind charges. This level of control is essential for balancing gameplay in a modpack. The add-on is built for Forge on 1.20.1, and it integrates with Architectury API and FTB Library for NBT editor support. If you are looking to streamline your modpack setup, the foxygame.net launcher offers a one-click install for Just Trial Spawners, ensuring version compatibility and automatic updates so you can spend less time troubleshooting and more time playing.
How to Install and Download
To download Just Trial Spawners, you will need to have Forge installed for Minecraft 1.20.1. Once your mod loader is ready, simply place the downloaded JAR file into your mods folder and launch the game. The mod is released under the MIT License, so you are free to use it in any modpack, private or public, without needing permission.
