Reviving a creature

With a completed genome you are two machines away from a living creature.

Embryogenesis Chamber

Shaped ➜ Embryogenesis Chamber

The chamber combines a completed genome with an artificial egg and nutrients to make a fertilized egg of that species.

Embryogenesis Chamber

5 s➜

All three inputs are used up, including the cartridge. Each creature needs its own completed genome.

The slot below the genome is the donor slot. Leave it empty for a normal embryo, or put a second genome there to make a hybrid.

Genome traits

The chamber decides the embryo's traits from the genome's fidelity, and they stay with the creature for life:

Trait	Effect
Size	80–120% of the species' normal size. Bigger animals also hit harder
Vitality	Maximum health
Vigor	Movement speed
Temperament	Calm, steady or fierce. Calm animals are easier to keep comfortable, fierce ones harder
Sterile	Can't breed
Frail	30% less health

A high-fidelity genome gives a healthy, fertile animal close to its species' norm. A poor one spreads the traits wider and makes a sterile or frail animal more likely. The fertilized egg, the capsule and (with Jade) the creature itself show its traits.

Hybrids

Some species can be spliced together. Put a completed genome of one parent in the genome slot and a completed genome of the other in the donor slot (either way round). Both cartridges are used.

• Hybrids have no fossils of their own; this is the only way to make one.
• The hybrid's fidelity is 85% of its parents' average.
• Every hybrid is sterile.
• A hybrid enters the Species Journal the first time it is made.

The hybrids on the Creatures page list their parents, and JEI shows every known pairing.

Artificial Egg

Shapeless ➜ Artificial Egg

Shaped ➜ 4Nutrient Solution

Egg Shell Fragments come from brushing suspicious sand and gravel at dig sites. Nutrient Solution is made from any potion (a Water Bottle is fine) and bone meal, and one craft makes 4.

Incubator

Shaped ➜ Incubator

The incubator keeps the fertilized egg warm until it's ready to hatch. How long depends on the species; bigger creatures take longer.

Incubator

50 s➜

Triceratops shown. Incubation ranges from 45 s for the smallest species to 140 s for Argentinosaurus. See each species on the Creatures page.

Upgrades

Every machine has two upgrade slots. In these two machines:

• Precision: the Embryogenesis Chamber treats the genome as 8% more faithful per module. The Incubator gives a frail embryo a 35% chance per module to come out healthy.
• Efficiency: in the Embryogenesis Chamber, each module gives a 25% chance to keep the Nutrient Solution.
• Speed: each module cuts processing time by a third.

See Upgrade modules.

Releasing your creature

Baby Creature Capsule

Use the Baby Creature Capsule on a block to release a baby of its species. You become its owner: it grows into an adult over time, and once grown you can saddle and ride it. It starts out roaming around the spot where you released it; see Keeping creatures for how to give it orders and keep it happy.

Capsules can't be used on Peaceful difficulty, or where too many creatures already live nearby (see Population limit).

Breeding

Two adults of the same species can be bred by feeding them their diet items. Instead of a baby appearing, they lay an egg on the spot. It hatches after the species' incubation time into a baby owned by the nearest player within 10 blocks. With Jade installed, look at the egg to see how long is left.

Both parents must be:

• fertile: sterile animals and hybrids can't breed,
• at least settled (comfort 50 or more),
• below the population limit. An egg also waits to hatch while the area is full.

The baby inherits the average of its parents' traits with a little variation, so a good bloodline stays good. It usually takes one parent's skin.
