Crystalline eye

You turn a piece of glass into a crystalline eye that within range, the caster can see from as long as they are concentrating.

You mentally receive visual information from the eye, which has normal vision and darkvision out to 30 feet. The eye can look in every direction.

The crystalline eye will only dispel if dispelled by the caster, the caster falls unconscious or dies, or the eye is destroyed.
