Mutations

Mutations are one of the ways to make your crabs stronger or change how some parts of the game work.
You purchase mutations with DNA which you earn through Crab Evolutions and progressing further down the riverbed.
There are 36 Mutations in total, each one costing more than the previous to unlock (see the table below).
Each mutation has two benefits. The top benefit is a bonus to the Damage of a specific colour of crab, or All crabs.
The bottom benefit is specific to that mutation, ranging from damage increases to timer adjustments, etc.
Read through the Library to learn more about the individual mutations. Take your time, there is a lot to learn.
We've included a Priority List that may give beginners some idea of what to strive for. You are under no obligation to follow it.
Each mutation you unlock adds a bonus % of DNA when you Ecdysis.
Each completed mutation Set also adds additional bonus % of DNA.
Full DNA information is contained within the DNA article.

You may hear players discuss "rerolling" or "resetting" their mutations.
If you click on the picture of your mutation, the window will have a button to Extract it.
Extracting a mutation removes it from your list and gives you back all DNA spent on it plus the cost to unlock another mutation.
The cost (in pearls) increases based on the number of mutations you have unlocked, and the level of the specific mutation you want to reset.
TIP: If you are wanting to remove a mutation but are afraid to break up a complete set and lose the 30% bonus - hopefully you have Ember Tipped Carapace already. Buying three levels of ETC will give you back the 30% that you are losing from your set bonus.

We have a Worksheet to play around with your DNA and decide how best to spend it.

Each mutation has a cost to research (unlock) that gets progressively more expensive as you unlock more and more of them.
