3e SRD:Attacks of Opportunity
Attacks of Opportunity
Threatened Squares
A character threatens the area into which it can make a melee attack, even when it is not a character's action. An enemy that takes certain actions while in a threatened area may provoke an attack of opportunity from a character. A small or medium sized character normally has a 5-foot threat radius.
Reach Weapons
"Reach weapons" and "natural reach" can change the threatened area.
Moving
If a character moves through (not simply into) or out of a threatened area, a character usually provokes an attack of opportunity.
If all a character does during that character's turn is make a normal move or a double move (not a run), the space that the character started out in is not considered threatened.
If a character's entire move for the round is 5 feet the 5 foot move does not provoke an attack of opportunity.
Performing a Distracting Act
A character taking some kinds actions provokes attacks of opportunity, as described in the rules for each action type.
Making an Attack of Opportunity
An attack of opportunity is a single melee attack, and a character can only make one per round. The character does not have to make an attack of opportunity if the character doesn't want to. The character makes the attack of opportunity at the character's normal base attack bonus.
