🧬 Mob Evolution

Kill a mob. Its entire species evolves. Forever.

You kill 10 zombies. Nothing happens. You kill 10 more. Suddenly the zombies start teleporting behind you. Then they gain life steal. Then lightning. By the time you hit 600 kills, you're fighting something you created.

Mob Evolution turns your own kill count into the difficulty setting. Every world evolves differently, because every ability is rolled at random.

⚙️ How it works

1. Kill mobs. Every kill adds points to that mob TYPE (zombies, pigs, creepers, etc.).
2. Evolve. At 10, 30, 70, 150, 300 and 600 kills, the species jumps up a tier.
3. Get a new ability. Each tier gives the species one random new ability, so a mob can end up with up to 6 abilities.
4. It's permanent. Every mob of that type gets it, including ones already alive. Progress saves with your world.

You always know where you stand: a progress bar after each kill ("Zombie: 7/10 kills to evolve") and a big announcement when a species evolves.

🐷 Yes, even pigs

Every mob can evolve, not just monsters. Passive mobs get their own set of abilities: Ram Charge, Moo Blast, Egg Bomb, Kamikaze, Stampede, Stink Cloud and more. They need 2x the kills by default, and an anti-farm cooldown stops spam-killing from evolving them instantly.

🎛️ You control it

You get a Nether Star when you first join. Use it to open the menu:

• Evolution speed: x0.5 / x1 / x2
• Turn individual abilities on or off
• Passive mob kill multiplier and anti-farm cooldown
• Toggle chat announcements and the kill progress bar
• See progress for every mob type
• Replay the built-in tutorial

Villagers and iron golems are excluded by default, so trading and village defense stay normal.

❓ FAQ

Can I reset the evolutions? Yes, with /scriptevent evo:reset. Is it too hard? Lower the speed in the menu or turn off abilities you don't like. Does it work with other add-ons? It should work alongside most, but some mods that change mob behavior may conflict. Tell me if you find one. I found a bug or have an ability idea. Leave a comment! Updates are planned.
