Wizard Eye

With this spell the caster creates an invisible magical "eye" through which they can see. The eye has Darkvision with a range of 30 feet, but otherwise sees exactly as the caster would. It can be created in any place the caster can see, up to a range of 240 feet away, and thereafter can move at a rate of 40 feet per round as directed by the caster. The eye will not move more than 240 feet away from the caster under any circumstances. The eye cannot pass through solid objects, but as it is exactly the size of a normal human's eye, it can pass through holes as small as 1 inch in diameter. The caster must concentrate to use the eye.
