You create a number of semi-tangible, visible magical orbs (called "eyes") equal to [10/12/14/16/18]. These eyes move out, scout around, and return as you direct them when casting the spell. Each eye can see 120 feet (normal vision only) in all directions.
While the individual eyes are quite fragile, they're small and difficult to spot. Each eye is a Fine construct, about the size of a small apple, that has 1 hit point, AC 18 (+8 bonus for its size), flies at a speed of 30 feet with a +20 bonus on Fly skill checks and a +16 bonus on Stealth skill checks. It has a Perception modifier of +[8/10/12/14/16] and is subject to illusions, darkness, fog, and any other factors that affect your ability to receive visual information about your surroundings. An eye traveling in darkness must find its way by touch.
Once per day, you may specify instructions you want them to follow in a command of no more than 25 words. Any knowledge you possess is known by the eyes as well.
In order to report their findings, the eyes must return to your hand. Each replays in your mind all it has seen during its existence. It takes an eye 1 round to replay 1 hour of recorded images. After relaying its findings, an eye disappears.
If an eye ever gets more than 1 mile away from the ritual node, it instantly ceases to exist. However, your link with the eye is such that you won't know if the eye was destroyed because it wandered out of range or because of some other event.
The eyes exist for up to 1 hour per caster level or until they return to you. Dispel magic can destroy eyes. Roll separately for each eye caught in an area dispel. Of course, if an eye is sent into darkness, it could hit a wall or similar obstacle and destroy itself.
