Combat Reflexes (Combat)
You can make additional attacks of opportunity.
Benefit: You may make a number of additional attacks of opportunity per round equal to your Dexterity bonus. With this feat, you may also make attacks of opportunity while flat-footed.
Normal: A character without this feat can make only one attack of opportunity per round and can't make attacks of opportunity while flat-footed.
Special: The Combat Reflexes feat does not allow a rogue to use her opportunist ability more than once per round.
Additional means, in addition to whatever you could normally make. Which means, if you can normally make one attack of opportunity, and have an 18 Dexterity, which is a +4 modifier, you can make 5 AoO's.
