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 this handy spell. 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 Downward Movement does exactly the opposite and enables a party to quickly move down a dungeon level.
