I think this is a little complex. Maybe something simpler such as this:

Name: Divining Orb (Third Eye Reflection)

Appearance: Floating crystal eyeball only visible to user and a mirror

Effect: Eye can pass through walls and magical barriers, showing what it sees on the mirror.

Balance Breaker: "Shattered Eye Spymaster" Allows creation of additional mirrors/eyes. Mirrors float around user.

Note: Sight-based attacks are transmitted through Sacred Gear. (In an HP universe, you would be petrified from looking at the basilisk with the eye)
