Veganism

Killing animals changes how they behave. Animals that are hit may take revenge, and nearby animals of the same kind can chase down the attacker and deal damage on contact. Screaming animals react to slain animals with a burst of red particles and a screaming-goat sound, and the strength of the revenge can be scaled by difficulty. Players can tune particle density and the chat lines that appear during an attack.

Once a player kills enough animals, the default being 3, Spirit Animals are summoned and the player is cursed with the Veganism effect. Eating non-vegan food gives back hunger, but applies Nausea and Hunger, and milk can cure the effect. Spirit Animals fight with skulls that deal little damage and do not break blocks, and their boss fight drops oak leaves and spawns four to seven random farm animals. A custom Wither boss is part of the same set of rules and has reduced XP drops, defaulting to 5 instead of the vanilla 50.

Veganism needs Cloth Config API and Fabric API. Mod Menu is optional and opens the settings screen. The mod runs on the client and the server, so the server and every player need it. The mod is available in Russian and English.
