you can easily test the above post on a duluhan in AK. When he does that sweeping swing with the conal red area, just try this, and maybe you can understand how it works. Be completely outside the red area when his cast bar finishes that move. And it takes a while for his big ass sweeping animation, so after hes done with it, run in front of him, and notice how that attack appears that it would stomp your face, does absolutely nothing to you, becuase you were out of the red when the cast bar finished. Now try the opposite, stand in the red, somewhere near the very edge, and when that cast bar finishes, run your ass for miles away, and notice that his slow ass animation afterwards, romps your face, because you were in the red when that bar finished.
