I want to start playing D&D again, so I've begun to read the PH.
unfortunately the wording of the Attack of Opporitunity is vauge!
help explain it to me.
as I understand it, a pc can get a "free" attack that does not count toward his round at any enemy who is adjacent to his 5' "square" if he is not making a full action?
I really don't get this.. If I'm fighting a gnoll in front of me and another one happenes to run by to attack another party memebr I'm just going to randomly take a swipe at him?
