Roaming Sight

Roaming Sight is a runic spell that appears in Ultima Underworld I and II.

Description
Roaming Sight allows its caster to scry into world around them, projecting their consciousness such that they might enjoy a bird's eye view of their immediate surroundings. While under the effects of this spell, a mage may move their vision across space, ignoring any barriers between themselves and what they wish to spy upon, allowing them to discern hidden chambers with relative ease. 

Trivia

 * This spell is surprisingly difficult to control. The camera it provides it can only turn slowly, and is often at risk of getting "stuck" in the dark spaces between rooms.
