We are the Wall

Prerequisites

Benefit Three times per day as a move action, you can declare a single dragon, magical beast, or monstrous humanoid within 50 feet and in line of sight to be your mark. You gain a +1 bonus on attack rolls and on Bluff, Knowledge, Perception, Sense Motive, and Survival checks against your mark. These bonuses last for 1 minute, until you designate a new mark, or until the mark is dead. After you have declared a creature as your mark, it can’t be your mark again for another 24 hours.
