Oak Strength (Ex)

Beginning at 4th level, the forest master gains a +2 bonus to Strength and the ability to make slam attacks. A Small creature's slam attack deals 1d4 points of damage, one from a Medium-size creature deals 1d6 points of damage, and a Large forest master's slam attack deals 1d8 points of damage. Slam attacks are natural weapon attacks and do not provoke an attack of opportunity from the defender. A forest master can select Improved Critical (slam), Weapon Focus (slam), and (if a fighter of 4th level or higher) Weapon Specialization (slam). Upon gaining this ability, the forest master's hair takes on a green, leafy appearance.
