At 6th level, an arcane archer can launch an arrow once per day at a target known to him within range, and the arrow travels to the target in a straight path, passing through any nonmagical barrier or wall in its way. (Any magical barrier stops the arrow.) This ability negates cover, concealment, armor, and shield modifiers, but otherwise the attack is rolled normally. Using this ability is a standard action (and shooting the arrow is part of the action). An arcane archer can use this ability once per day at 6th level, and one additional time per day for every two levels beyond 6th, to a maximum of three times per day at 10th level.
