Combat Patrol (Combat)Modifier
You range across the battlefield, dealing with threats wherever they arise.
Benefit: As a full-round action, you may set up a combat patrol, increasing your threatened area by 5 feet for every 5 points of your base attack bonus (to a maximum equal to your speed). Until the beginning of your next turn, you may make attacks of opportunity against any opponent in this threatened area that provokes attacks of opportunity. You may move as part of these attacks, provided your total movement before your next turn does not exceed your speed. Any movement you make provokes attacks of opportunity as normal.
Essentia: You gain a bonus of +1 / Essentia to hit with your Attack of Opportunity and the Area increase by +5ft / Essentia
