Since the OP's question seems to have been answered, does people have some trick for the part with the 4 clones doing half room cleaves ?

While i did understand how it is working, 4 half room cleaves from the clones before a 5th from the boss, the main problem i have with this part is that it is a lot of purple things on purple things behind other purple things all that on top of a floor which color is not that different from purple as well. Despite one of the guide i did see saying "the clones are dropping slowly and you have all the time in the world to adjust", it takes because of the all similar colors and the visual clutter so much time for me to finally see what the first two clones are going to do, that the whole sequence is already going boom, boom, boom, boom and boom, meaning that if i survive the last 3 hits or not is just a matter of luck.

I am already aware of the "look at the spinning boxes that are easier to see", and it doesn't change a thing because they are purple like all the rest. Is there some kind of special pattern that is always used, or is it really all random ?
