A CRB is an abbreviation for cotton root bark.

Where can I buy CRBS?
It can be purchased in oasis for 1gb! And it is constantly there year round!


What does CRB do?
This is the item information
This herb will induce a miscarriage on any pregnant lioness. The lioness will come back into heat again in 3 days. Her mutation chance will increase, as well as the lethality of the mutation. (1 use)

This means that once you breed your lioness you can use a CRB to lose the litter, this will put the lioness on a 3 day cool-down. Once that cool-down is up you can breed your lioness again, that litter will have an increased mutation chance.

Where does crb sit on the roll order? / compared to other mutation increasing items

Leopon OR Overgrown Fur OR Tigon ➜ Patches/Piebald ➜ GMO Cow/Lion Meat ➜ Cotton Root Bark ➜ Fertility/Natural Chance ➜ Lion Scrotum ➜ Primal ➜ Dorsal Fur ➜ Tigon Boost ➜ Mukombero ➜ Dorsal Fur Guarantee

As shown above CRB sits 4th on the roll order, meaning everything above it will override it. I don’t suggest patches/piebald studs (will go into more detail later in the guide) you can pair cotton root bark with GMO cow or lion meat for a higher chance at a mutation! - though you can only use one. As lion meat and gmo cows sit on the same slot, meaning one will override the other if both are used

Compared to CRB the order of the most mutation chance is put below

CRB - lowest mutation increase
LION MEAT - Middle mutation increase
GMO COW - highest mutation increase

IMPORTANT NOTE: Make sure if using ANY items on a lioness that you use the CRB first, otherwise you will override the litter with the items attached. So add crb THEN any other items.

Can crbs be stacked on themselves?
NO! Crbs cannot stack on themselves. You are able to apply the crb again but it will kill the litter, meaning you lose your first CRB. Crb results are generated upon breeding. Meaning you cannot stack them and you will essentially be wasting them.

Can I find CRBs elsewhere?
Yes! When claiming lioness from explore as a dreamboat male, there is a very small chance you can get a in heat CRBED female!

Tips ?
- Don’t IBF!
- claim as many NCLs as you can
- the bigger the batch, the less disappointing the results
- use red cocks to eliminate the chance of any female amps!
- use great tits to encourage female amps!

What Is a CRB project?
A CRB project is the action of Massbreeding crbs. It can be over the period of a long time or within a week, there is no limit. Some users (such as me) prefer to do larger batches of 40-100 at a time while others will sometimes only do 1-2 per roll.

What is the point of a CRB project?
The point of a CRB project is to mass breed mutations, either for resell or just personal desire. Using crb will increase your mutation chance therefore increasing the number of muts in your litters.

Why do people do CRBs?
People do crbs with a certain goal in mind (or just fun!) for example getting a G1 leopon. Here are some goals

Getting a G1 hybrid
Getting a lethal
Getting a DU
getting a dwarf
Getting every lethal
Getting every mut
Doing a certain amount of crbs

Some just do it for ANY mut! Or to build up mutations in their pride!

What are some of the mutations you can get from crbs
All mutations that come from CRBs are RANDOM MUTATIONS. Meaning you cannot get muts that are inherited.

The mutations you CANNOT get from crbs are..
Piebald/patches
Any type of primal
Overgrown fur
Dorsal fur

The mutations you CAN get from CRBS are..
Achromia
Blind
Bobbed tail
Folded ears
Clawless
Dwarfism
Eyeless
Melanism
Overgrown tounge
Overgrown claws
Overgrown teeth
Polycaudal
Tailless
Toothless
Adult female male mutations
First gen tigon
First gen leopon
First gen Jaglion
Double uterus

All mutations can be found Here!

Getting started with a CRB project can be intimidating!

Here’s a few suggest steps to get started!

STEP 1
Make a forum or document to keep organised and keep track of the results! I’ve posted a template below for users to use.

STEP 2
Save up currency for CRBs! Then buy a handful from oasis!

STEP 3
Claim/buy as many lioness as you have CRBs. Breed these lioness and then CRB them. You will need to wait the 3 day cool-down. Zebra hearts DO not help with the cool-down. Do NOT nest the lioness the first time you CRB. This is a waste.

STEP 4
Wait it out then breed again! This time DONT crb or anything! And make sure you nest these girls! And wait the 3 days for them to give birth!

STEP 5
Congrats you just did your first crb batch! If you got any muts you can either sell them or keep them for yourself!

Repeat!

With a crb batch obviously there’s a handful of things needed!

You should have the following things before starting a CRB batch.

- to amp check cubs
- nesting materials or autonesting
- for CRBs
- CRBS.
- patience & sanity
- territory space for both lioness and cubs
- a NON- piebald stud

Pros
- fun project to do
- may end up with a really rare mut!
- increase your prides mut count
- something to spend your gb on

Cons
- they are sometimes REALLY disappointing and disheartening.
- they will 99% never cover the cost you spent for that batch
- they are expensive
- mane mutations are a disease.

items to avoid
Any breeding items like lion scrot, crunchys etc are really a waste and I’d say the same about buffalo scrotum or grain of paradise. While it is tempting it is NEVER worth it.

DONT IBF! I know I know it’s SO tempting but again, it is almost never worth it.

Studs to avoid
Most studs are okay for CRB breeding, but some aren’t. Generation, looks etc do NOT matter. But if you have a piebald or patched stud I suggest not using them. It’s optional

The reason being, the piebald/patch runs on slot 2 of the roll order, meaning it overrides CRB. Which means if the CRB potentially rolls a nice random mutation and you have a piebald stud, there is a chance that piebald stud will roll on that same cub and erase the mutation replacing it with the piebald instead.

While this chance is SMALL. It is possible.

Any other stud such as primal, other muts, no mut etc is FINE to use! Anything but pie/patch!

While I can’t go into a full depth guide to get gb I’ve made a separate guide a while ago!

GB MAKING GUIDE

Additionally I suggest you sell any muts you aren’t interested in from these batches to continue doing crbs!

If you are interested in starting CRBS and want a community who are interested in the same project, there is a clan below that does CRB giveaways etc! Might be wise to join!

I myself have got into the CRBS. Before deciding if you’d like to do CRBS it would be wise to view my results, though I have been quite unlucky.
