Fusion inputs

Enter the income of the three pets you fused and, if you know it, the income of the result. The tool adds the inputs and compares them with the outcome.

How to use this comparison

Start with the three pets you actually fed into the machine and enter each income. That sum is what the fusion cost you in earning power. Then enter the income of the pet that came back.

If you have not fused yet, leave the result empty. The tool will show the combined input and wait, rather than assuming an outcome for you.

What this tool does not do

It does not predict a result, weigh rarity, or rank one fusion against another. Outcome and size are game decisions, and this page stays outside them.

It also does not value a fusion for trading. Trade demand is not visible in an income figure, so treat the net change as an earning reference only.

The tool adds and divides the values you type. It never estimates a fusion outcome, a size roll or a probability, because no verified source publishes any of them.

FAQ

Does this predict what fusion will produce?

No. Outcome and size rolls are decided by the game, and no verified source publishes the probabilities. This tool compares only the numbers you already have.

What do I enter for the result?

The income of a pet you actually received, or of the outcome you are planning for. With no result entered, only the combined input is shown.

Why compare against all three inputs?

Fusion consumes all three pets, so the honest baseline is the sum of everything you gave up. Comparing against one input would overstate the gain.

Is a bigger pet always better?

Not necessarily. Fusion can roll a smaller size than the pets you put in. Only the recorded income of the result is read here.

Where do the income values come from?

From this site's dated pet record, or from your own in-game reading. Your own reading takes priority when the two disagree.
