Stormal in Sol's RNG: Drop Rate, Biome & How to Get It
| Rarity tier | Unique |
|---|---|
| Base drop rate | 1 in 90,000 |
| Native rate (in biome) | 1 in 30,000 |
| Biome | Windy |
Stormal is where most players' aura hunt gets serious: a 1-in-90,000 Unique that becomes dramatically easier to chase when the Windy biome rolls in, cutting the odds to 1 in 30,000.
Because Windy is one of the more frequent biomes, the practical play is patience — save your luck potions until the wind picks up, then roll through the whole window. Stormal also matters beyond bragging rights: its Hurricane evolution (1 in 13.5M) starts here.
Improving your odds
Every luck potion multiplies your effective rate — see the potions & luck guide for exactly how the stacking works, and the biomes guide for how Windy windows behave. Free potions come from active codes; the full odds table for every aura lives in the aura index.
