Knowledge

At 1st level, you can temporarily become a master of lore. For 1 minute, you gain the bard's lore master ability. At 10th level, as a swift action, you can make a touch attack against a creature. If the attack is successful, you learn all of the target's weaknesses, gaining a +2 insight bonus on attack and damage rolls, saving throws, and AC against that creature (the bonus on attack rolls is doubled on rolls made to confirm critical hits). This effect lasts for 1 minute.
