Attack of Opportunity

An Attack of Opportunity is a free chance for a character to strike during combat when an opponent exposes themselves to danger. To make an attack of opportunity, a character must be wielding a melee weapon and be actively ready to attack.

An attack of opportunity is triggered when a nearby creature (within 2 meters) performs one of the following actions:

• Attempts to flee from combat
• Charges toward another target
• Uses a ranged weapon while in melee range (such as a bow, crossbow, or throwing weapon)

When an attack of opportunity occurs, the attacking character may attempt a normal attack roll (AR) or meet any other required conditions to determine success. In short, an attack of opportunity provides a chance to strike, but does not automatically hit.

Example: A fighter is ready in melee combat. An enemy attempts to flee 2 meters away. The fighter receives an attack of opportunity and must roll an AR to determine if the strike hits.
