A Depressing Look at ETC

Ember Tipped Carapace is a much-loved mutation that adds bonus DNA when you Ecdysis. Click Here to read more about it.

Why is it Depressing?

Go ahead and start raising the level in the What If column. You'll see why.

What If...?

  • Each new level of ETC adds 10% of your Base DNA.
  • Your What-If level (0) adds 0 extra DNA per run at this distance.
  • The cost of DNA to make that upgrade is 0.

I Can Afford That.

  • If you have that much DNA now and continue Ecdysis runs at 0 meters, it will take 0 additional runs before this purchase becomes profitable..


  • You are spending an amount of DNA to buy ETC levels.
  • Each level you buy gives you a small boost of bonus DNA per Ecdysis.
  • At some point in the future, that level will pay itself off.
  • That's what we mean by profitable.
  • Until then, ETC is still paying off your purchase cost.
  • As you go higher distances and earn more DNA, this will pay off faster.
  • Got It, Thanks.

I Don't Have That Much DNA!

Let's see when you can reach your What-If Level of 0.

  1. Starting Ecdysis Level
  2. Current Unspent DNA
  3. What percent % of your ecdysis DNA do you want to spend on ETC?
  4. Do you want to spend extra DNA on other stuff or save it up for more ETC?
    Save : Spend
  5. Use Current or What If values for ecdysis DNA calculations?
    Current : What If
  6. Do you want to see a full table or just the summary?
    Summary Only : Table Also
ETC Purchase Summary
  • Using 0 of each Ecdysis' DNA.
  • Saving all unspent DNA each run.
  • Using Current values for runs at 1000 meters.
  • Costs include your unlock cost of 0 DNA.
  • You can buy What-If level 0 on Ecdysis 0 (0)
  • You would fully profit from this purchase on Ecdysis 0 (0)
  • You CANNOT reach your target What-If level without either spending a higher % of DNA or saving up.

Using your golden reptile spawn chance and gold boss chance (if applicable), we calculate an average per-reptile gold amount that you might receive at this distance. For comparison purposes only and does not include Midas Swarm or Emerald Strand because those are both hard to quantify and wouldn't amount to significant gold.


This is the amount of gold you would receive on average killing all reptiles in this 10m section of the riverbed, including the boss. Also for comparison purposes only.

Ember Tipped Walkers

ETW reduces the number of reptiles per section of riverbed. Less reptiles might mean a higher average gold, but the total gold for the section might be less.

A Note on Multipliers These multipliers might be bigger than those shown on Spending DNA because these represent everything: mutations, genes, gold from evolutions and queens, and Claw of Midas. Spending DNA focuses specifically on mutations.

The Daily Boss

The Daily Boss, the Wildebeast, Big Blue (he needs a name) appears at midnight your local time. His health calculation "is complicated." Explain.

  • Based on the distance you are when his button appears.
  • Is a little harder if you have fought him before.
  • Gets a little harder as you get further from that base distance.
  • If you go several hundred meters beyond when he appeared, he will seem very easy.
  • Use the calculator below to find his health.
  • Got It. Thanks.
  1. Note: If you Ecdysis after he appears, he resets to be based on your new Ecdysis distance, so change the worksheet to that distance and enter that here instead.

  2. Did you Ecdysis after his button appeared? Yes : No
  3. Is this your first time fighting him? Yes : No
  4. He can't spawn ahead of 0m
If you fought him now at 0, his health should be 0 (or 0 from What-If).


  • Using Jade Tipped Pincers level
  • If you Ecdysis at this distance, you should start at 0m.
  • You are saving approximately 0 (assuming you can insta-kill from 0m-0m)
  • You should start with approximately 0 gold.
  • Using What-If data, you should start with approximately 0 gold.

Simulated Run

Using the power of Math, we can sorta estimate where your realistic maximum distance is located by performing a general simulation of your run down the riverbed.

Running a simulation with no data is pointless - for that reason you need to be signed in and have a cast of crabs on your account to use this simulator.
