ICARUS Ubis Breeding: Serum and Seven Phenotypes

Quick Answer

ICARUS Ubis phenotypes became a breeding collection goal in Week 236. Start at the Ranching Station and craft the new Ubis Serum; the official update identifies that serum as the entry point for establishing a breeding population. Juvenile Ubis could already be collected and raised before the update, but breeding is the new husbandry step. There are seven distinct Ubis phenotype variations to discover, collect, and breed. Use the live serum recipe and current husbandry interface for ingredients and requirements. The official source does not give serum quantities, inheritance probabilities, pairing formulas, gestation time, feeding rates, guaranteed phenotype combinations, or a fastest route to all seven, so those values stay Unknown.

Before you set out

Prerequisites#

  • Use Week 236 build 3.0.14.152723 or later.
  • Have access to the Ranching Station and its live Ubis Serum recipe.
  • Distinguish collecting or raising a juvenile Ubis from breeding an established population.
  • Prepare husbandry space and normal animal care from current in-game prompts rather than guessed values.

How to breed Ubis phenotypes in ICARUS#

Ubis were already part of the swamp environment, and juvenile animals could be collected and raised before Week 236. The update adds the missing population loop: prospectors can now breed them. RocketWerkz places the start of that loop at the Ranching Station, where a new Ubis Serum is crafted. The release also confirms seven phenotype variations, giving the breeding system a clear collection goal. That is the full verified boundary. It does not publish a genetic model, dominant or recessive rules, parent-to-offspring percentages, mutation chances, timing, or a guaranteed combination chart. The safest guide therefore separates three actions—collecting a juvenile, raising an animal, and breeding a population—and directs numeric questions back to the current live interface. Record the live recipe requirement, eligible animals, parent pair, and visible offspring phenotype as separate observations. That creates a useful collection log without implying that a repeated outcome proves an inheritance percentage or that seven verified variants guarantee a fixed sequence.

Route 02

Start an Ubis breeding population#

Follow the verified serum entry point and record outcomes without turning observations into universal odds.

  1. Confirm Week 236 or later#

    Check the client and host build before looking for breeding controls. An older server can still support raising juveniles without the new breeding loop.

  2. Locate the Ranching Station#

    Use the current technology and crafting interfaces to find the Ranching Station. The saved source names the station but does not define a permanent unlock level or material list.

  3. Open the Ubis Serum recipe#

    Read the live ingredient list, quantity, craft time, and unlock state. Do not copy guessed values from another build into the current recipe.

  4. Craft the required serum#

    Produce the Ubis Serum that Week 236 identifies as the breeding entry point. Preserve the exact current UI if a requirement appears missing.

  5. Prepare the animals and space#

    Use current husbandry prompts to confirm the animals and environment are eligible. This release does not specify a universal pen size, food quantity, or pairing formula.

  6. Begin the breeding interaction#

    Apply the live husbandry flow after the serum is ready. Follow the current interface rather than assuming that collecting a juvenile alone starts breeding.

  7. Record each phenotype separately#

    Track visible offspring phenotype and parent pair. Seven variations are verified, but the source does not name a guaranteed inheritance path.

  8. Avoid claiming odds from a small sample#

    One or several offspring can document an outcome, not a universal probability. Keep inheritance chance and fastest-completion claims Unknown.

  9. Repeat only within normal care limits#

    Continue the husbandry loop using current animal needs. Do not infer timers, feeding rates, or guaranteed combinations from the existence of seven phenotypes.

Pocket list 03

Verified Ubis breeding boundaries#

  • Ubis became breedable in Week 236.
  • Juvenile Ubis could already be collected and raised before breeding was added.
  • Breeding starts with an Ubis Serum crafted at the Ranching Station.
  • Ubis have seven distinct phenotype variations.
  • The official source does not publish the serum recipe quantities.
  • Inheritance probabilities, formulas, gestation time, feeding rates, pen size, and guaranteed combinations remain Unknown.
  • Record the current build, animal identity, growth state, serum availability, parent pair, care indicators, and observed offspring phenotype together; one breeding result documents an outcome but cannot establish a universal probability.
  • Seven phenotype variations define a collection goal, not a promise that seven attempts produce seven different outcomes; repeated appearances do not prove that another phenotype is unavailable.
  • If the serum is missing, compare client and host versions and read the live Ranching Station unlock state before guessing a hidden level, substituting another item, or moving to an unrelated crafting bench.
  • Keep ingredient quantities, animal needs, breeding duration, and eligibility attached to the observed live interface because the Week 236 announcement introduces the system without freezing those numeric values.
  • When comparing community breeding reports, require the same game build and separate a pictured offspring from a claimed probability. One screenshot can identify an appearance, but it cannot verify the parents, care state, number of attempts, inheritance formula, or fastest route to every phenotype.
  • For a useful follow-up, label whether each animal was collected as a juvenile, raised before Week 236, or produced through the serum-enabled breeding loop. That history prevents ordinary raising, breeding eligibility, and offspring phenotype from being mistaken for the same state.

Fault ledger

If Ubis breeding does not start#

The Ubis Serum is missing
Confirm Week 236 or later and check the Ranching Station, not a generic crafting bench. Record the current unlock state rather than inventing a prerequisite.
A raised juvenile has no breeding action
Separate raising from breeding. Confirm the serum step and follow the current husbandry eligibility prompts.
The offspring repeats a phenotype
Seven possible variations do not guarantee a new one on each breeding. Record the outcome without assigning unsupported odds.
A guide lists exact inheritance percentages
Treat those numbers as unverified unless they are tied to current authoritative evidence. Week 236 does not publish percentages.
You need exact food or timing values
Use the current animal and husbandry UI. Those values are outside the saved official source.

Field questions

Ubis breeding questions#

Where do I start breeding Ubis?
Craft the Ubis Serum at the Ranching Station; Week 236 identifies that as the start of the breeding population.
How many Ubis phenotypes exist?
The official update confirms seven distinct variations.
Is collecting a juvenile the same as breeding?
No. Juveniles could already be collected and raised; Week 236 adds the separate breeding loop.
What are the inheritance odds?
The cited release does not publish them, so they remain Unknown rather than guessed.
