You gain a +2 bonus on saving throws made against enchantment spells and effects and against mind affecting spells. In addition, you gain a +2 bonus on Escape Artist and CMB checks made to break free of a grapple or to escape bindings.
Only the strong thrive in the River Kingdoms, and you are no weakling.
Whenever you are struck for more than 20 points of damage with a single physical melee or ranged attack, reduce the amount of damage you take by 1 point. Once per day, if you have at least 1 hit point and a critical hit would otherwise kill you (even with reduced damage), you are instead reduced to -1 hit points (but you are stable).
