I'm in an argument about taking a five foot step in combat and whether or not it provokes an AoO. in the PHB, it does state that taking a 5 foot step does not provoke AoOs but as part of the * it states that regardless of the movement, if you move out of a threatened square, you provoke an AoO. So my question is, in combat, if you take a 5 foot step out of a threatened square, do you provoke an AoO? I'm saying it does because you move out of a threatened square regardless, but he's saying no. So i'm just trying to get this clarified.
