Mutation Calculator
Compare mutation changes, with or without a known base value.

3 growth + 4 environmental optionsWhat changes from this scenario?
Keep the unmutated base fixed and compare the supported combinations. A move from Wet to Frozen replaces Wet; it does not add both. Every row is a hypothetical configuration, not a claim that it is currently obtainable.
| Growth / environment | Total multiplier | Multiplier difference | Relative multiplier change | Estimated value |
|---|
Relative change = (new multiplier − current multiplier) ÷ current multiplier × 100. For a fixed positive base, this is also the estimated value change. At a zero base, every estimated value is zero. Values outside the calculator’s numeric limits are labeled separately.
Try a useful question: choose Gold, Wet and Shocked, then compare the Frozen + Shocked row. The multiplier moves from 2,020× to 2,180×: +160×, about +7.92%. With a hypothetical base of 100, the difference is 16,000 Sheckles. Follow the derivation or compare different base values and ranges.
