Uus Por

Uus Por (Upward Movement) allows teleportation to the next upper 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 up to the next higher level or the outside. However, this worry is past once they have a spellcaster in their midst with Uus Por (Upward Movement). Once known as Y (Up), it essentially is a weaker version of Xit and allows the party to float up through the ceiling to the next higher dungeon level.

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

In Sosarian Magic, equivalent spells existed: Sur Acron and Rec Su.

Trivia

 * Casting this spell in Ultima V on the 8th level always leads to the Underworld. That way, one can save themselves quite some headaches on these levels.
