I'm not exactly sure what you mean by flurry of blows, but there is the stunning blow, which if successful means your opponent is stunned for the next 6 rounds and you really whale on them. hit the special abilities button on the bottom far right of your character's icon tray, then click on the icon that looks like a fist punching down through lightning. center the attack cursor on the opponent you want to hit with the stunning blow. Your monk will automatically for the next 6 turns attempt to hit with it. If it works, then they are stunned. Then you can really stomp them. Is that what you were talking about?

When given a choice, take both.
