EvoCraft turns Minecraft's animals — and a few of its monsters — into a living genetics system. Every creature you tame, breed, or leave alone in the world quietly accumulates evolutionary pressure from its environment, its diet, and its lineage. Left long enough, a chicken isn't just a chicken anymore — it's carrying traits, stat modifiers, and eventually full mutations that change how it looks, what it produces, and what it can do.
Nothing in EvoCraft is hard-coded per animal. A single generic engine drives every creature in the mod: vanilla chickens, cows, sheep, pigs, wolves, zombies, skeletons, spiders, creepers, endermen — and three fully custom creatures the mod adds on top (the Rockling, a climbing lizard companion; the Penguin, a colonial seabird; and the Eagle, a flying scout). If it has a profile, it can evolve, mutate, and be bred toward something better.
A creature exists in the world
↓
It survives, eats, fights, gets exposed to its environment
↓
It slowly accumulates Evolution Points and Environmental Pressure
↓
It advances through EVOLUTION STAGES (Natural → Evolved → Mutated → Advanced → Alpha → Legendary...)
↓
At higher stages it has a chance to roll a MUTATION — permanent, inheritable
↓
Breed two mutated parents → offspring inherits mutations & traits, generation ticks up
↓
Rare VARIANT TIERS (Shiny, Alpha, Ancient) can appear on top of all this
Nothing here is fast by design. A single mutation roll is never guaranteed — it's a probability shaped by rarity weight, the creature's environment, its traits, and (if you're using one) an active Evo Zone. You're not grinding for an outcome, you're building the conditions that make a good outcome more likely, generation after generation.
Right-click a creature with the Gene Scanner for a quick read, or hold up the Evolution Scanner (works like a spyglass) for the full profile: species, generation, stage, tier, traits, mutations, fitness, and — if it's standing in one — Evo Zone exposure. You cannot manage what you can't see, and both tools are cheap.
Chickens have the fastest evolution rate in the mod. They're the practice species — breed a flock, feed them, let time pass, and you'll see your first mutations (Iron/Golden/Diamond Feathers and friends) faster than with anything else. Iron/Golden/Diamond chickens double as a genuinely good passive resource farm once established.
Mutations and traits inherit with real probability weighting — pairing two mutated parents is dramatically better than hoping a wild one rolls something on its own. If you want a specific elemental line (Frost, Storm, Magma, Void…), find or breed toward a parent with a mutation in that family, then pair it with another from the same line.
Once you've found an Abandoned Genetic Research Facility (rare underground structure) and looted an Ancient Evo Core, you can build an Evo Zone Generator. Insert a Zone Core (Cryo, Thermal, Storm, Overgrowth, Crystal, or Mutation) and it projects a radius of environmental pressure that nudges resident creatures toward that line's mutations over time — without ever guaranteeing one. It's a breeding accelerator, not a cheat button. A Cryo Zone full of Penguins is, bar none, the fastest way to eventually land an Ice Walker.
Rarity runs Common → Uncommon → Rare → Epic → Legendary → Mythic. Higher tiers are dramatically rarer to roll but generally stronger, and several lines have an explicit upgrade path where one mutation replaces an earlier one once you meet its requirements.
🏆 Diamond Feathers (Chicken) — Legendary The end of the chicken resource line. A Diamond Chicken periodically produces diamond shards passively. Nine shards craft into a diamond, so a small flock is a slow but genuinely meaningful diamond farm that costs nothing but time and wheat.
🏆 Alpha Dominance (Zombie) → Zombie King — Legendary Turns a zombie into a rally point: nearby zombies get combat buffs while it lives. Zombie King is the evolved form — rarer, stronger, and the closest thing the hostile side has to a boss encounter you generate yourself.
🏆 Ancient Core (Creeper) → Creeper Overlord — Mythic The top of the creeper explosive line. Do not fight this near your base. Worth encountering once for the scanner readout alone.
🏆 Thunderbird (Eagle) — Legendary Requires an eagle to already have Shock Bite and be Advanced stage or higher — it's a deliberate capstone, not a lucky first roll. Massive boosts to Shock Bite, Talon Strike, and Soaring. The signature "I bred toward this for weeks" mutation of the Eagle line.
🏆 Royal Plumage (Eagle) — Mythic The rarest eagle mutation in the game (weight 0.25, requires Alpha tier). Grants heavy Loyalty, Talon Strike, and Scouting. If you see one in the wild, tame it immediately.
🏆 Ice Walker (Penguin) — Epic Requires Cold Resistance and Advanced stage; replaces Cryogenic Feathers. Freezes a small patch of water into ice as the penguin walks over it — mostly cosmetic/utility, genuinely fun to watch, and the clearest "I built a Cryo Zone and it worked" payoff in the mod.
🏆 Aurora Feathers (Penguin) — Mythic Requires both Cold Resistance and Shock Bite, plus Alpha stage — the hardest prerequisite combination in the penguin line. Replaces Conductive Feathers. If you have one, you did the work.
Every "themed" creature line (Rockling, Penguin, Eagle) follows the same shape — pick one element, breed toward it:
| Element | Rockling | Penguin | Eagle | Zone that helps |
|---|---|---|---|---|
| Frost | Frost Rockling | Cryogenic → Ice Walker | Glacial Plumage | Cryo Zone |
| Fire | Magma Rockling | Thermal Adaptation | Ember Talons | Thermal Zone |
| Storm | Storm Rockling | Conductive → Aurora Feathers | Storm Pinions → Thunderbird | Storm Zone |
| Blood/Dark | Blood Rockling | — | Spectral Plumage | — |

These aren't crafting-table recipes — smelt in either a regular Furnace or a Blast Furnace (Blast Furnace is just faster, same output).
| Input | Output | Furnace time | Blast Furnace time |
|---|---|---|---|
| Mutagenic Crystal | Mutagen | 200 ticks | 100 ticks |
| Raw Stabilite | Genetic Stabiliser | 200 ticks | 100 ticks |
| Stabilite Ore | Genetic Stabiliser | 200 ticks | 100 ticks |
None of these work in a Smoker — Furnace or Blast Furnace only.
