About this project
What does Trial Glow add?
Trial Glow
Trial Glow is a datapack that allows you to ring a bell on top of a trial spawner to make all its mobs glow!

How to use:
- Place a bell on top of a trial spawner
- Ring the bell by right-clicking it
- The glow effect will now be applied to all mobs spawned from that trial spawner!

Details
Ringing a bell will only highlight the mobs spawned from the trial spawner below the bell. Only mobs already spawned before ringing the bell will be highlighted (meaning mobs spawned after ringing the bell will not be highlighted). Mobs are highlighted for 30 seconds.
Compatibility
This datapack is automatically compatible with any mod and/or datapack that adds trial spawners in its structures. A popular example is Dungeons and Taverns
