- Base energy
Changes the weather to a sandstorm for nine actions.
The user can either create a widespread sandstorm that ravages all non-Ground-, Rock-, or Steel-type Pokémon (1% damage per action), or shroud only itself in a concentrated shield of whirling dust to deflect incoming projectile attacks. Rock-type Pokémon have one more level of resistance than normal to Special attacks as long as the sandstorm rages, Moonlight and Morning Sun heal only up to 33% when under its effects, and Solar Beam's power is halved so long as Sandstorm is in play. In addition, visibility is greatly reduced for all Pokémon caught in the sandstorm, though Pokémon already vulnerable to it thanks to their typing have even more difficulty seeing than those that resist the storm's effects.
