Root Abyss Boss Mechanics

something i've noticed:

vellum popping out of the ground didn't kill my mercedes (did around 7k hp though, out of 7.7k) while on my DrK it hits over 20k. i'm not too sure of the numbers so i'll try to recheck today, but it could be that they follow a certain formula where they deal a base damage plus an amount depending on your total HP

for example (and this one i did notice) von bon's blue little ball thinguie hit my mercedes for 10k-ish or so, ohkoing, while on shinku it hit for 80k-ish or so, leaving me alive with 5% or so hp left.

so it definitely scales somehow (and pierre's ohko attack hit 55xxx K on my DrK, three times.)

I noticed Von Bon's ground smash and ball attack do not kill my mercedes, and it has only 16k HP. It does about 14.4k, which is the HP i would have without the Kaiser link skill.
