Breeding is done in a laboratory. You must have both a male and female sample to make a new egg. The samples are a one time use only.

Below is a simple to follow guide originally written by afflikshon on breeding higher tiers.

  • It is recommended to name the critters with numbers (ex. II, III) to denote the generation of the critter.

When breeding 2 critter species together, you only need to breed the higher tier creature with the lower tier creature 1 time (Exp: Breeding a Spider and a Fish together, and then breeding that offspring with another Fish (and that offspring with another fish) is all that is required. This is misrepresented as 'tier skipping', because you create a Tier 3 creature, by breeding Tier 1 creatures together repeatedly after they have been bred with the Tier 2 at least once. It is also much cheaper and easier to breed higher level creatures, as you gain more extractions from the lower tier creatures, while taking the same amount of generations to reach the final goal.

Tier 1 Breeding[]

Tier 1 is the lowest level of the breeding line. They are the critter you start with and are required in tier 2 and tier 3 breedings. This group includes birds, fish, lizards, moths, wolves .

TIER 2 BREEDING[]

Raptor: To get a raptor, breed a lizard with a bird. Your offspring will, obviously, be a lizard or bird. I recommend naming it with a “II” at the end of its name to denote that it’s second generation. Take your second generation (whether it’s a bird or a lizard) and breed it with ANY bird or lizard. Name the offspring with a “III” at the end of its name. Then, take the third generation lizard/bird, and breed it with ANY lizard or bird. The offspring of this third generation will be a raptor.

Spider: To get a spider, breed a wolf with a moth. Your offspring will, obviously, be a wolf or moth. I recommend naming it with a “II” at the end of its name to denote that it’s second generation. Take your second generation (whether it’s a wolf or moth) and breed it with ANY wolf or moth. Name the offspring with a “III” at the end of its name. Then, take the third generation wolf/moth, and breed it with ANY wolf/moth. The offspring of this third generation will be a spider.

Owlbear: To get an owlbear, breed a wolf with a bird. Your offspring will, obviously, be a wolf or bird. I recommend naming it with a “II” at the end of its name to denote that it’s second generation. Take your second generation (whether it’s a wolf or bird) and breed it with ANY wolf or bird. Name the offspring with a “III” at the end of its name. Then, take the third generation wolf/bird, and breed it with ANY wolf/bird. The offspring of this third generation will be a owlbear.

TIER 4 BREEDING[]

Tier 4 egg

A "Tier 4"egg

I’m not going to write out all of the Tier 4 breeding patterns since they get lengthy. The rule of thumb is this: you must go two more generations than you did for Tier 3. So, the offspring of your SEVENTH generation offspring will be Tier 4. Here are the combos:

Dragon: Breed a raptor with a crocodile.

Hydra: Breed a spider with a calamari.

Gorilla: Breed a mammoth with an owlbear

Lion: Breed a steed with a mammoth

Tortoise: Breed a walrus with a toad.

Mantis: Breed a crustacean with a hornet.

TIER 5 BREEDING[]

T5 Egg

A tier 5 is made by combining two tier 4s.

Beholder: Breed a Hydra with a Mantis for 15 generations.

Cerberus: Breed a Gorilla with a Lion for 15 generations.

Wyrm: Breed a Dragon with a Tortoise for 15 generations.




GESTATION TIME[]

Calbulating an egg's gestation time is a little complicated. It depends on the tier and generation of the samples being used.

But the way to calculate the gestation time is this:

  • T1 sample = 3 hours
  • T2 sample = 6 hours
  • T3 sample = 9 hours
  • T4 sample = 12 hours
  • T5 sample = 15 hours

Thus if you breed a T1 sample with a T2 sample your gestation calculation will be 3+6=9.


Gestation time per Tier (only breeding the same Tier to the same Tier) is:

  • Tier 1: 6 hours
  • Tier 2: 12 hours
  • Tier 3: 18 hours
  • Tier 4: 24 hours
  • Tier 5: 30 hours


For example:

when you breed a Tier 3 with a Tier 1, the gestation time is 12 hours.


The Mathematical Method of Breeding Tier 2 is as follows:

1st Generation: X + Y = X/Y

2nd Generation: X/Y + Y/X = X/Y

3rd Generation: X/Y + Y/X = Z

Where X is a female sample of one species, and Y is a male sample of the other necessary species.

X/Y is the newest offspring, and Y/X is the opposite species and gender to X/Y.

Z is the new tier critter.

For each tier up, 2 more generations are added to the process.(but rumors says 13-15 times for t5)

e.g. Tier 3 would require 5 stages of breeding, and the offspring of the 5th gen will be Z.

TAINT BREEDING[]

Taint Breeding is a misrepresentation of the process that utilizes Taint (taint is foreign genetic material of another species in a sample due to being bred in a previous generation with another creature, only creatures that are linked to a higher Tier creature will produce a tained sample). It does NOT leap forward in Tier's (like using 2 T1's to breed a T4), but simply uses the higher Tier critter a single time, instead of 1 for each generation.

Let's use the example of making a Calamari. You will still need both a fish and a spider in this process.

To begin, breed the fish with a spider. Do this until you get a fish as the offspring. At this point, you may discard all your spiders. Afterward, breed the resulting fish with another fish. The second fish does not need to be of spider lineage. Continue doing this for 5 or 6 generations. On the last generation, a tier 3 egg should appear.

- Shorter egg hatching times. You need 12 hours every gen after the first, instead of 15 hours using the normal method. You might need one or two generations more, but you have shorter generations, so the total time is the same, or less, with tier skipping. Also, most notably for T2->T4,(example: crustacean(t2) to mantis(t4) it's pretty easy to be online every 12 hours to get started with the next generation, but being online every 15 hours is not do able for most people, so you'll lose even more time with the normal method. If you have the tokens for eggcells, this part is a non-issue, though...

- You can take more samples from the critters in each gen. In the normal method, almost every other generation you have to sample a T3, which only has 2 extractions, bit with tier skipping you always sample T2s, with 3 extractions each. This means you can mass breed T4s easier if you want more of them, instead of just 1-2

- Easier to find mates for each gen. With the normal method you need to have a sample that is both of a different sex AND of a different species. With tier skipping, you just have to worry about the different sex.

- Easier to transfer apps to the higher tier. You just need to get the right apps on the T2 critter, taint it once with some random T3 you found in the auction, or PU, or wherever (you'll lose some apps here, but you'll get those back later), then just continue with tier skipping. You'll have 7-9 breedings to transfer all the missing apps back into the tainted bloodline, which is more than enough (really, 3-4 gens should be enough even for 6 apps, unless you are very unlucky). With normal breeding, you usually have to get the right apps on both T2 and T3 critters before attempting to go towards a T4 with the same apps (or try to transfer the apps directly on the T4 after you breed it, which can be quite difficult due to the low number of extractions and the lengthy breeding times and needs to be done separately for each T4 you breed). If you breed a gen 2 with a gen 2 both raptors tainted with croc dna you will get a dragon this effectively makes taint breeding much shorter than normal

It has been proven that taint breeding does work with T4s.

-Mutant breeding. Mutant takes between 20-25 generations of cross breeding maybe less or more. The chances to get mutant may increase with more generations of cross breeding(I'm not fully sure). Also mutant seems to have the ability to change the family instead of an app.
