Aurora paints northern-light shimmer onto ready crops—52× weather environmental value that polar event weeks screenshot heavily, without ever stealing the growth slot Rainbow can still claim.
mutations.ts: northern lights shimmer from aurora borealis weather. weather.ts Aurora Borealis lists Aurora, Rainbow, and Celestial. Multiplier 52, weather category, stackable true. Keep crops mature for that named forecast; unpublished aurora-fox radii or ribbon schedules are out of scope.
Weather tie-in: Aurora Borealis · Full mutations guide
Aurora is weather-category environmental and stackable. Solo → 52. Aurora + Celestial (120×) → sum 172, count 2 → 171. Aurora + Crystal (55×) → sum 107, count 2 → 106. Rainbow from the same weather entry is growth, not env—only one growth tag applies. Aurora has no CONFLICT_PAIRS row.

Aurora applies a 52× multiplier in the weather bracket. The table below shows the value it adds to a reference crop (base 50) across common harvest weights, so you can gauge how much this tag is worth before chasing it.
| Weight | Base crop value | With Aurora (52×) | Value added |
|---|---|---|---|
| 1 kg | 50 | 2.6K | +2.55K |
| 2 kg | 200 | 10.4K | +10.2K |
| 5 kg | 1.25K | 65K | +63.8K |
| 10 kg | 5K | 26K | +255K |
weather.ts puts Aurora, Rainbow, and Celestial on one aurora window. Aurora and Celestial are environmental; Rainbow is growth. Seeing all three icons means growth × [1 + (52 + 120 − 2)] if Rainbow is the growth winner—not a three-way env product that includes 50× inside the bracket.
Starlit (24×) and Moonlit (8×) can pad night-adjacent stacks when those icons also appear. Aurora + Starlit → sum 76, count 2 → 75. Additive bracket only.
A 52× aurora tag does not multiply Celestial’s 120×. Traders who post “52 × 120 aurora packs” misread formulas.ts. Correct framing: sum the env multipliers, subtract the tag count, then multiply by one growth factor.
Plant so harvest falls inside Aurora Borealis uptime. If Crystal Rain later adds Crystal beside leftover Aurora, recount n; each new env icon both raises the sum and increases the subtracted count.
Aurora Borealis windows are short enough that leftover shimmer cosmetics without the Aurora harvest id price like skins, not 52× environmental weight. Capture the crop panel with Aurora visible, then run growth × [1 + (sum − count)] for the exact icon set before posting a WFL ask.
On lighter bases, kilograms still decide whether a solo Aurora beat a heavier Crystal (55×) twin. Polar prestige is visual; weight squared is what Discord buyers verify against the calculator.
