Wind Change

Wind Change is a powerful meteorological spell.

Spell Description
Successful travel by sea or balloon is at the whim of the wind. A ship can't effectively sail against the wind, and a balloon always drifts with it. So what to do if the wind isn't blowing in the direction a magic-user wants it to be? Cast Wind Change. It will change the direction of the wind for a while, thus cutting down travel time significantly. For any frequent traveller who doesn't use Gate Travel, this is an effective tool.

Ultima Saga
In Lynn Abbey's Ultima Saga, Rel Hur was one of the most common of scrolls, and one that Balthan can cast himself, but only works at sea.

Quote

 * "Magic doesn't make weather."


 * "You can change the way the wind blows," Althea reminded him. "You said that Felespar made more Wind Change scrolls than any other kind, and that you could cast the spell yourself..."


 * "Rel Hur works over water." Balthan gave his attention to the bedraggled feathers in his hat.


 * "This isn't water?" Drum gestured at the bog.


 * The magician adjusted his hat over his forehead. "An ocean, Drum. Rel Hur doesn't change the way the wind blows, it creates a very big illusion over a very big body of water."

- from The Temper of Wisdom (Ultima Saga)

Trivia

 * The Magic Fans in Ultima VI have the same effect.
 * This spell uses the same Words of Power, REL HUR, than Weather from later games. However, Weather is more powerful, affecting not only the wind, but complete storms.
