"Though the fur of the feral croc might seem, at first, to grow in a random fashion, the careful observer will note channels in the fur which permit air to pass and cool the beast. Typically, air flows freely over the creature's body before continuing on its way, yet on rare occasions it leaves the channels, swirling instead around the nooks and crannies of the croc's strange physiology. There the wind takes on tangible form, and so is the substance known as the antarctic wind formed."
The Antarctic Wind(南極の風,Nankyoku no Kaze?), also known as South Wind, is a recurring, single-use item in the Final Fantasy series that frequently is used to cause some form of ice damage to one or more targets. Its upgrade is generally the Arctic Wind.
The Antarctic Wind appears as a Throwing weapon dropped from Suzaku, with a special use: if it is thrown at Genbu, it disables his additional water damage on melee attacks, making it easier on the tank. The Arctic Wind serves an inverse function.
The Antarctic Wind can be bought for 300 G in Guera, Urbeth, and Invidia, won from Silky and Wight, or found in Guera, Invidia, and Spelvia. Due to the elemental system used within the game, the item inflicts water-elemental damage instead of the traditional ice-elemental damage.
