So my current character has a 5ft and 10ft reach with his sword, if I take the Combat Reflexes feat he can make 5 more AoOs, if an enemy moves from my 5ft treaten to 10ft and out do I get 2 attacks or just the one for leaving my range?
Slightly off topic, but Barbarians and Skalds get Unexpected Strike, which is pretty cool. It allows AoO's when an enemy enters a threatened square. Fun to get.
