Notes
For abilities that change the weather, the game sets a variable, X, to 1 whenever the player enters a new floor. At the beginning of each round, if X equals 1, the game triggers the weather-changing effects of each Pokémon’s abilities, in the order below. Then, X rises by 1 and, if it is equal to 36, is set to 0. The order in which the effects are applied is below.
- Drizzle -> Sand Stream -> Drought -> Air Lock/Cloud Nine
