[RPG] AoOs against the same enethe on his turn

dnd-3.5eopportunity-attackpathfinder-1e

I have seen this question for D&D 4e: Attacks of Opportunity from moving within a threatened area? and I was wondering about attacks of opportunity in Pathfinder/3.5e.

If an enemy goes from one threatened square to another one threatened by the same guy twice, and the threatening creature has combat reflexes and enough dexterity, could he be making more than one AoO against the same enemy for that movement?

As an example, imagine that a Medium size creature (A) with 5ft. reach charges against a Large humanoid with a reach weapon and a non-reach natural attack (e.g. a bite), Dex 20 and Combat Reflexes (B).

B threatens from 20ft to 10ft with his reach weapon and from 10ft to 5ft with the bite. For a total of 4 squares threatened on a straight line.

So, does A provoke three AoOs from B whenever he charges, for leaving 20ft., 15ft. and 10ft. during the same move?

Further, lets say B gets Hold the Line feat, which states:

Benefit

You may make an attack of opportunity against a charging opponent who
enters an area you threaten. Your attack of opportunity happens
immediately before the charge attack is resolved.

Does A now provoke an AoO from B for both entering and leaving these squares, for a total of 6?

Best Answer

Sorry, one movement only provokes one AoO from a given defender.

See the d20pfsrd:

If you have the Combat Reflexes feat, you can add your Dexterity modifier to the number of attacks of opportunity you can make in a round. 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). Moving out of more than one square threatened by the same opponent in the same round doesn't count as more than one opportunity for that opponent. All these attacks are at your full normal attack bonus.

So if you shriek "SERPENTINE!!!" and run circles around your opponent, they still only get one "leaving a threatened square" AoO on you.

The opportunity from Hold the Line is different, but only works once upon them entering your threatened area. So you would get only one from Hold the Line and one for them leaving a threatened square.

Note that the leaving a threatened square is per round - not even just per turn - with the Mythic rules in use in our WotR campaign we've been finding a lot of cases where you get to act multiple times in a round, even charge multiple times, etc. If by hook or crook someone charged you, ran off, charged you again, and ran off again over the course of a round (on their turn or across multiple turns), you would still only get 1 AoO for them leaving your threat but could get multiple from Hold the Line, if they actually leave and enter your threatened area with a charge twice. Up to the limit of the number of AoOs you have.
