Wizard Eye

Danger can be everywhere. The Peer spell might be nice to get a get overlook of the surrounding terrian, but it doesn't warn the caster of enemies. However, if scouting is needed, Wizard Eye is best for it. It creates a magical eye that will scout out the surroundings for the caster, reporting all kinds of danger.

After a set amount of time, the eye will dissolve into nothing, leaving no hint to the foes that they'd been spied on.
