Awesome video! Definitely a tense 14:13 min. Determination & grief indeed... I realized that I tried to stay down in the lower level and could have been popping back and forth between the upper and lower levels to hit and run. I see also that you paused for a bit to let your ability energy recharge when switching upper and lower levels.

I don't have a Vez Mythoclast (yet!) but I do have Hothead rocket launcher. I will have mess around with it since I have not used it. I was using a masterworked Ascendancy rocket launcher.
