Benefit: The magus can spend 1 point from her arcane pool as a swift action so that her attack creates a hypnotic pattern, weaving an arcane matrix that lulls her foe into quite a state of distraction. With his defenses down, she can strike him more easily. She chooses a single target that she can see. This foe must make a Will save (DC 10 + half her magus class level + her Intelligence modifier) or the foe lose his Dexterity bonus to Armor Class against her attacks (and only her attacks) for 1d6 rounds. This is a mind-affecting ability.
