Wind Change

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.

Trivia

 * The Magic Fans in Ultima VI have the same effect. They can be found in the pirate treasure and Utomo's house in Yew.
