Benefit: The recipient gains a +1 insight bonus to Defense and on Reflex saving throws. If caught in a situation when his Dexterity bonus isn't applied to his Defense, this bonus to Defense and saving throws does not apply.

Additionally, he gains a +4 bonus on Listen and Spot checks made to act in a surprise round.
