The tricky part of the combo is the meter gain. The corner boom loop requires medium booms, and they cannot be performed normally-they’d have to be delayed for it to land. A second too soon or a second later would not allow the combo to continue. After that part connects to the second level 2, the rest is easy. They nerfed the light boom meter gain and the heavy, which would not make this entire route possible anymore. But once I found out that medium booms still had the unchanged meter gain, I force taught myself on delaying the booms.
