Root Abyss Boss Mechanics

For some reason I don't feel like Von Bon's little energy ball is actually a ohko, it seems more like it takes off around 95% of my hp. I kept dying right after his attack but I realized it was because I wasn't at full health. The attack takes off a certain amount for me based on my current total hp, which explained my deaths. After I switched to using power elixers instead of ginger ales I was at 100% hp all the time and that attack of his stopped ohkoing me. I rarely jump over that attack of his now, I just take it and keep attacking. I play a lumi.

I did start dying again after my friend hyper bodied me, but that was because Von Bon's energy orb started hitting me for 11ks instead of 7ks and I just didn't notice the HB in time to pot back up to max, heheh.
