Sand Stream
4 Pokémon can have Sand Stream: 4 as a regular Ability.
What does Sand Stream do?
The weather changes to a sandstorm when this Pokémon enters battle. It lasts five turns (eight if the Pokémon holds a Smooth Rock). If multiple Pokémon with this ability, Drizzle, Drought, or Snow Warning are sent out at the same time, the abilities will activate in order of Speed, respecting Trick Room. Each ability's weather will cancel the previous weather, and only the weather summoned by the slowest of the Pokémon will stay. Overworld: If the lead Pokémon has this ability, the wild encounter rate is halved in a sandstorm.
