Des Por

Des Por (Downward Movement) teleports the party to the next lower dungeon level.

Spell Description
Sometimes it is really annoying for a party of adventurers to find their way through a labyrinth of a dungeon to find the ladder that leads down to the next lower level. However, this worry is past once they have a spellcaster in their midst with Des Por (Downward Movement). Once known as Z (Down), it essentially allows the party to sink through the dungeon floor to the next lower dungeon level.

The spell Uus Por does exactly the opposite and enables a party to quickly move up a dungeon level.

In Sosarian Magic, equivalent spells existed: Dor Acron and Rec Du.

Trivia

 * A more powerful version of this spell, Des Por Vas, was mentioned in Lynn Abbey's Ultima Saga.
 * In Ultima IV and Ultima V, casting this spell on the first dungeon level always leads back to the surface. That saves the time normally spent on finding the exit ladder.
