## Spectral Skirmisher *You have trained extensively in the use of magic that renders you invisible. In combat, you use this experience to vex your opponents and increase your survivability.* **Prerequisite:** Base attack bonus +6 **Benefit:** While you are invisible, you gain additional benefits. Creatures unable to see you due to invisibility take a –5 penalty on all Perception checks to detect you. A creature using a melee attack against the square you occupy provokes an attack of opportunity from you. You must choose to make this attack before checking to see if the creature finds you. If you attack and hit, the creature automatically finds you in your square.
