Crown of Maze Navigation

The Crown of Maze Navigation is a magical item appearing in  Ultima Underworld.

Description
While being on the 7th level of the Abyss, the Avatar learned that the evil Mage, Tyball, had erected a deadly maze, which was the only way to his lair. The maze was sadistic in that only one path would be safe, and stepping away from it would suck out the lifeforce of the unwary. Worse, the correct path looked the same as the deadly parts of the fairly extensive maze. The Avatar had however also heard of a countermeasure to the maze, and found the Crown of Maze Navigation amongst the treasures of an Imp. Wearing this crown, the normally invisible path became visible and allowed safe passage of the maze.

Trivia
