Still about combat reflexes and AoO, What I want to know is, does a single "action" that involves multiple "acts" that provoke an AoO actually provoke multiple AoOs from the same creature?
Ex: An archer that fire 2 arrows (ranged attack action) in a barbarian's treat range, will he take 2 AoOs, one from each attack?
Yes. AoOs are provoked per act/trigger, not per action. So each time you fire an arrow is a separate AoO. Another example is casting a ray spell: it provokes once for casting and again for ranged attacking.
Thank you StabbittyDoom and all that did give a fast answer.
My friends were arguing with me bcs of this text in placed in AoO (combat section):"This feat does not let you make more than one attack for a given opportunity, but if the same opponent provokes two attacks of opportunity from you, you could make two separate attacks of opportunity (since each one represents a DIFFERENT opportunity)."
So 'different' they understand like 'kinds' of opportunity, that cant be the same, like two same maneuvers in the same round, or an archer firing 2 arrows...
But I think now its clear
