Simoom

"Scourge foe with a poisonous wind."

Simoom is a Jupiter Djinn found in Golden Sun: Dark Dawn. Obtainable once you and your party are sea-worthy, Simoom is a random encounter on the world map on the biggest of a series of five, small, deserted islands located in the south-west corner of the sea.

When cast, Simoom summons two whirlwinds onto your target dealing damage with a chance of poisoning.
