At the expense of attention to other distractions, you focus on a single opponent to gain an advantage.

Prerequisites: None

Benefit: Once during your turn as a free action, you can designate a single opponent. You gain a +1 insight bonus on attack rolls, AC and saving throws against that opponent. In exchange, you take a -2 penalty on attack rolls, AC and saving throws against other creatures. The bonus and penalty last until the start of your next turn.
