YDM's Iceologer

The mod brings the Iceologer, a mob proposed in the 2020 mob vote, into cold landscapes. When summoned, it leaves Ice Chunk blocks behind, and those can only be mined with a tool enchanted with Silk Touch. The mob can appear in a range of icy terrain, from open plains of frost to frozen water, and the frozen peaks entry excludes jagged peaks.

Spawning is controlled by a config file found in the run folder. Server owners can set the spawning biomes, spawn rate, minimum and maximum number, and the time between Ice Chunk summons, where 40 ticks equal 2 seconds. Biome names use the modid:name form, and several biomes are listed separated by commas, so the mob can also spawn in biomes from other mods. Since version 1.19, spawn settings are replaced by biome tag and biome modifier JSON files stored in the data folder of the jar.

The mod is client and server, so the server and every player need it. It is published for Fabric, Forge and NeoForge across 8 release versions, 1.17.1 – 1.21.8, and is released under All rights reserved, so it is not open source.
