A mesmerist can focus his stare on one creature within 30 feet as a swift action. That creature takes a –2 penalty on Will saving throws. This penalty changes to –3 at 8th level. A mesmerist can maintain his stare against only one opponent at a time; it remains in effect until the mesmerist stares at a new target, the opponent dies, the opponent moves farther than 30 feet away, or the mesmerist falls unconscious or dies. The mesmerist can remove the memory of his stare from the target's mind; the creature doesn't remember that it was affected (nor does it realize that it is currently being affected) unless the mesmerist allows it. The hypnotic stare is a psychic effect, and relies more on the mesmerist's focus than the target's perception of his stare. It can't be avoided in the same ways a gaze attack can. The mesmerist can use this ability even while blinded, but must succeed at a DC 20 concentration check to do so. Staring at a creature requires the mesmerist's focus, so if he uses a gaze attack or similar ability, he must target the subject of his hypnotic stare or voluntarily end the stare. The penalties from multiple mesmerists' stares don't stack, nor do they stack with penalties from witches' evil eye hexes. This is a mind-affecting effect.
