Trial Glow
Trial Glow makes mobs spawned by a trial spawner glow once a bell placed on top of the spawner is rung.
What it does
While the bell is rung, mobs that the trial spawner produces receive a glow effect, so they stand out against the surrounding area. The effect is applied to the mobs the spawner releases, not to every mob in the world.
The mod is server-side and runs on Fabric, Forge, NeoForge and Quilt. It is also offered as a data pack for servers, and it is open source under the MIT License. Files are published for game versions 1.21 – 26.3, with 1.2.0+mod for 26.3 as the latest file on every loader, dated 2026-10-13. Snapshot builds are not part of the release list.
Only the server needs the mod installed for the glow to work. Players can join without installing it, so a client copy is not required.
Key features
Bell-triggered glow
Ringing a bell placed on top of a trial spawner gives the mobs it produces a glow effect.
Glow on spawned mobs
The glow is applied to mobs the trial spawner releases, so the effect is limited to those mobs.
Bell placement on spawners
A bell can be placed on top of a trial spawner to serve as the trigger for the glow.
Data pack option
The same behavior is offered as a data pack, for servers that prefer not to add a Java mod.

Use cases
Spotting spawned mobs in a trial chamber
A player rings the bell so that the mobs released from the spawner are easier to pick out in a dim or crowded room.
Who it’s for: Server owners who run trial chambers and want the mobs from the spawners to stand out, and players who want a visible cue when a trial spawner releases mobs.
