YDM's Glare

The glare was proposed in the 2021 mob vote. Once tamed, it can be bred with glow berries. The mob reacts to the light level around it: it shows the areas dark enough for hostile monsters to spawn, and it flies toward dangerously dark spots, where it can throw a tantrum that leads monsters to gather.

Spawning can be widened into other biomes. The config file takes a biome list written as modid:name, so a biome from another mod such as biomesoplenty:cherry_blossom_grove can be added, and several biomes can be listed together, separated by commas, for example minecraft:desert and minecraft:forest. On 1.19 and later the spawn settings are replaced by biome tag and biome modifier JSON files, found under the data folder of the jar. Config changes take effect after the game restarts.

Files are released for Fabric and Forge across eight game versions, 1.18 – 1.20.1, and the environment is client and server, so the server and every player need the mod. The code is closed: the mod is released under All rights reserved and is not open source.
