Actions of Opportunity
From Legends of Cphera
Actions of Opportunity are any combative actions that characters perform against enemies that are Presenting an Opening.
In general, if a character is hit by an Action of Opportunity they automatically fail to complete the action that left them open in the first place (i.e. fail to stand up from prone, fail ranged attack), but there are exceptions. The use of magic, for example, almost always allows the use of the Concentration skill to avoid automatic failure as a result of damage.
The following are a list of actions that can be performed as Actions of Opportunity:
Performing some of these actions may make you Open, but you are never open against the person whose opening you are taking advantage of.
