Attack of Opportunity

If an opponent moves out of a square adjacent to you or performs an action that forces them to let down their guard, you can spend a Reaction to make a single, immediate attack against that opponent. This is called an Attack of Opportunity.

Provoking an Attack of Opportunity

Two actions can Provoke Attacks of Opportunity; Moving through or out of a Threatened area, or Performing a distracting action in a Threatened area.

Moving through or out of a Threatened Area

When you Move through or out of a Threatened Square, you provoke an Attack of Opportunity. You do not provoke an Attack of Opportunity if you use the Withdraw Action, if you successfully Tumble with an Acrobatics check, or Parkour/Push through the area with an Athletics check.

Involuntary movement, such as being the target of a Shove or the Move Object Force Power, never provoke Attacks of Opportunity.

Performing a Distracting Action in a Threatened Area

Performing an action that distracts you from defending yourself, or requires your guard down while in a Threatened square; provokes an Attack of Opportunity.

The following actions Provoke Attacks of Opportunity:

• Making an Unarmed Attack without the Martial Arts feat
• Aiming a ranged weapon.
• Reloading a Weapon
• Picking up an Item
• Retrieving a Stored Item
• Moving through an Opponent's Square
• Standing up from Prone
• Using any Skill that distracts you or forces you to drop your guard (GM's determination)
• Or any ability that designates an action as a proper provocation.

Making Attacks of Opportunity

An Attack of Opportunity is a single reactionary attack you may make against your opponent if they perform any actions that would provoke an attack. You can only make one Attack of Opportunity per Round, and you don't have to make an Attack of Opportunity if you don't want to. An Attack of Opportunity is always made at your full attack bonus, minus any situational penalties you suffer.

• You can't make an Attack of Opportunity if you're Flat-Footed or otherwise denied your dexterity bonus.
• If your target has any form of Cover against you they are no longer considered Threatened.
• Due to the reactionary nature of Attacks of Opportunity, they are not eligible for empowerment through most feats. For a feat to affect an Attack of Opportunity it must explicitly state that it does.

Melee Attacks of Opportunity

Melee weapons Threaten all of the squares within the weapon's Reach.

Ranged Attacks of Opportunity

Ranged weapons don't threaten any squares, unless their weilder has the Overwatch feat.

COMBAT REFLEXES

If you have the Combat Reflexes feat, you can make more than one Attack of Opportunity during a round. However, you may only make one Attack of Opportunity per provoking action. (Moving any number of squares is treated as a single provoking action.)
