Open

Magic users are mostly pragmatic people. However, there are some that think magic trumps everything and frown on physical work. The jimmying of a door or chest with lockpicks is beneath them. Instead they use this spell, which automatically has a 100% chance of picking the lock, as long as the lock isn't too complicated (meaning it needs a special key). As a bonus, this spell also includes the Destroy Trap spell, which will disarm any kind of trap on the targeted spell, while the lock is opened.

It can be used on locked doors as well, but only mechanical locks; magically-locked doors require the more-powerful spell Unlock Magic.

Trivia

 * A spell named Open in Ultima I was used to safely disarm coffins, rather than chests.
 * The Ultima VI spell Curse uses the same Words of Power as this spell in Ultima V: AN SANCT.
