Mutations from Thunderstorm
Worked example: a Carrot after Thunderstorm
| Setup | Total multiplier | Sell value (Sheckles) |
|---|---|---|
| Carrot, no mutation | x1 | 20 |
| Carrot + Shocked | x100 | 2,000 |
| Carrot + all 2 mutations | x101 | 2,020 |
Carrot base value 20 Sheckles at 0.275 kg. Value = base value x mutation multiplier x variant x (weight / base weight) squared, and mutations add up instead of multiplying. A fruit rarely gets every mutation from one weather; the last row is the ceiling. The wiki says some fruits pass through an extra value curve it does not publish, so in-game prices can differ.
