Axolostry
by _Wintr__
Axolostry lets players breed axolotls inside vivariums, where each pairing follows a recipe and the offspring inherit traits from both parents.
What it does
Each pairing takes place in a vivarium and is governed by a recipe. Some recipes need a particular fluid or a supporting block placed beneath the vivarium, and different recipes call for different vivarium tiers. Crossing species yields new varieties, and some species appear only after earlier stages or the discovery of other axolotls.
A pairing produces a temporary hybrid that transforms once a countdown ends. During the transformation the vivarium displays a hybrid texture built from both parent species, and the final offspring is chosen according to the chances set by the recipe. Fish feeding restores health, and pufferfish reduce adult health while speeding up the hybrid transformation.
Adult axolotls produce resources based on their species, and vivariums and machines use those resources in production. Axolostry runs on Fabric and NeoForge for 1.21.1, is licensed under the Creative Commons Attribution Non Commercial Share Alike 4.0 License, and is not open source. Both the server and every player need it.
Key features
Recipe-based breeding
Each pairing follows a defined breeding recipe, and the recipe sets the required parents, fluid, tier and outcome chances.
Trait inheritance
Offspring inherit characteristics from both parents, and an analyzer displays each axolotl's genes to help pick specimens for later breeding.
Species discovery
Crossing species produces new varieties, and some species become available only after earlier stages or the discovery of other axolotls.
Resource production
Adult axolotls produce resources based on their species, and the rate depends on the vivarium setup.

What the author says
Axolostry expands Minecraft’s axolotls with a progression system based on genetics, controlled breeding, vivariums, machines, and resource production. The mod is inspired by Forestry: select suitable parents, analyze inherited traits, discover new species, and develop breeding lines that produce useful materials.
