What Fire is actually worth
One plant on the Outer Ring at level 1, with and without Fire applied. Because the mutation multiplies a harvest the ring already multiplied, a 10x mutation is worth far more on an expensive crop than a cheap one.
| Seed | With mutation | Gain |
|---|---|---|
| Liberty LilyCelestial | $238M | +$214M |
| Admin StarrootExotic | $36.1M | +$32.5M |
| Buzzthorn BloomSecret | $3.4M | +$3.1M |
Values use the harvest formula: unit price × 1.25^(level − 1) × cash multiplier × mutation × ring × (1 + saw bonus / 7), calculated at level 1 with no cash multiplier and no saw bonus.
How to get Fire
Fire is spray-only — no weather event rolls it. You apply it with the Fire Spray, which costs $1qd in the Gear Shop when it is in stock. The Gear Shop restocks every 5 minutes, so check back regularly if it is not listed.
