What's included

22 creatures, each with its own behavior, attacks and visual effects:

Minds · Machination · Sinister · Beauty · Detritus · Fiend · Fend · Friend · Blitz · Eeper · Nothing · Canary · Vertigo · Coat of Arms · Dreamweaver · Cannonball Crab · Minedflayer · Mockingbird · Pathogen · Blossom · Saint Solis · Stained Glass

Plus the original content (see Not included below for the exceptions):

• Items and weapons: flintlock, heavy axe, vertigo horn, dream catcher, open mind, bouquet, vitric arrows and more
• Blocks: carapace, murky pearl, down feathers (with mosaic variants), wallpaper, doohickey and more
• Status effects, custom screen effects and shaders
• Armor trim materials, music discs and advancements

Changes from the original

Not included

• Toadstool and Runic Stone Bricks: they are built on Sable, a physics library that only exists for Minecraft 1.21.1. There is no Sable for Forge 1.20.1.
• Galena Hats (Team Galena's supporter top hats): the original only bundled it and never used it in its code.
• The original's unfinished, source-only content (Powder Skull, Trichael, Fish Eye, Wraith…).

Adapted to 1.20.1

• Blighted brain: still gives Nausea, Infested and Oozing (1.21 effects). With Trials Chambers installed (optional) it uses that mod's Infested and Oozing; without it, built-in copies of the 1.21 behaviour (silverfish when hurt, slimes on death).
• 1.21-only vanilla content replaced: Breeze sounds → similar 1.20.1 sounds; Open Mind is crafted with a crafting table (no crafter) and the Heavy Axe with a netherite ingot (no heavy core).
• Natural spawns: same biomes, weights and group sizes, with 1.21 biome tags translated to Forge 1.20.1 ones.
• Detritus loot: with Looting I/II one drop is slightly more likely (19 % / 24 % instead of 15 % / 22 %); same chance with Looting III and without Looting.
• pathogen = true (server config): "temperate overworld" becomes "overworld, neither hot nor cold" (1.20.1 has no temperate tag).
• The mod's armour trims no longer need Blueprint (still optional).
• No built-in config screen: edit the config files, or use a mod like Configured.

Fixed (bugs of the original)

• On dedicated servers, the Tools creative tab (and JEI) lost several items (vertigo horn, open mind, dream catcher, bouquet, solar shard, murky pearl…); fixed.
• A Murky Pearl fired from a dispenser became a snowball; it is a Murky Pearl now.
• After F3+T the canary's haze screen effect stopped updating; fixed.

Added

• One switch per creature in the server config ([creatures], all on by default = original behaviour). A disabled creature never spawns and vanishes without drops; spawn eggs and /summon still work for admins.

Compatibility

• Trials Chambers (optional): the blighted brain uses its Infested and Oozing effects.
• Goety (optional): recipes accept either mod's ectoplasm, plus 1:1 conversion recipes.
• Optional loot compatibility with Oreganized and Caverns and Chasms, and tag support for Blueprint.
• Works on dedicated servers.
• No extra dependencies needed: MixinExtras is bundled.
• Custom shaders may look different with some shaderpacks (Oculus).

Made with the help of AI (Claude Code) and tested in game: alone, in a 371-mod modpack, and on a dedicated server. Full list of changes: CHANGES.md in the jar and on GitHub.
