3rd-level / Setting Sun
The Setting Sun school teaches a fighting style that emphasizes using an opponent’s strength and momentum against him. By sizing up a larger opponent and studying his fighting stance and tendencies, you aim your strikes at vulnerable points on his lower body that he cannot defend effectively. While you are in this stance, you gain a +2 bonus on attack rolls and deal an additional 2d6 damage with weapon attacks against opponents of a larger size category than yours.
