You create a clone of yourself that steps out of your reflection holding a notebook and pen that it cannot be physically separated from. While the spell is active, you do not have a reflection. You have a telepathic link with the clone that can hold up to 5 miles. You may command it to go to any location and study anything. It will investigate any object you tell it to or interview any person you wish and write the results into its notebook. When the spell ends whether it be by choice or it runs out, the clone flies back to you at a speed of 1 mile a second. When it reaches you, you will retain any information it found about the subject and any relevant information about its surroundings. The clone has the following properties:

• The clone is translucent and its features are mirrored. It is clearly an illusion.
• It acts exactly as you would and it cannot physically touch or interact with any objects or creatures but it can be killed. It has half of your hp - 20 with a minimum of 5. 
• It cannot lie but it can choose to withhold any information it feels may lead to an inability to research the subject.
