Attacks of Opportunity are one of the more controversial aspects of newer versions. I’ve gone back and forth ever since they were first introduced. On one hand, they make sense. When one combatant performs certain actions, their defenses are reduced giving their opponent an advantage which is represented by a free extra attack. On the other hand, AoO add a level of complexity to combat that many groups don’t want to deal with.
Regardless of your feelings on the matter, I think you’ll enjoy this video.
Since this is not intended to be an actual discussion of AoO, comments have been disabled. I will certainly file the topic away though for a future article.
