Penetrating Vision
Penetrating Vision (sometimes called "X-ray vision") lets you see through solid objects. Each level of this advantage allows you to see through up to six inches of normal matter. You can just barely see the outline of the substance you are looking through – not enough to impair vision in any way. Penetrating Vision automatically works in conjunction with all your other vision advantages (Infravision, Ultravision, etc.).
