Effects in Battle[]

Damages all Pokémon except Rock-, Ground- and Steel-type Pokémon
Will increase the Sp. Def. of Rock-type Pokémon by x1.5
SolarBeam's power is reduced by half
Synthesis, Morning Sun, and Moonlight will recover 1/4 of the total HP, instead of 1/2
Weather Ball changes to Rock-type and doubles inpower.
Castform's Forecast however doesn't change Castform's type, so it will still be damaged by Sandstorm.
The Smooth Rock increases the duration of the sandstorm.
Pokémon with the Sand Veil ability will not be affected, even if they aren't a Rock, Ground or Steel type Pokémon (for example, Cacnea is a Grass-type and has the Sand Veil ability, so it doesn't get damaged), and will also have a 20% increase in evasion.
Pokémon with the Sand Stream ability will create a semi-permanent sandstorm upon switching in
