OA真的不是一个free action而是一个not an action。。。它都不是动作了为什么会打断动作
An attack of opportunity “interrupts” the normal flow of actions in the round.
If an attack of opportunity is provoked, immediately resolve the attack of opportunity, then continue with the next character’s turn (or complete the current turn, if the attack of opportunity was provoked in the midst of a character’s turn).
嗯,这么说OA是个针对轮提出的一个特殊的“动作”,的确不应该是个action。
