This is a thread that I wanted to make back then when I was playing NG2 intensively but never did so now that I'm playing again after some months -and I'm in the middle of a Mentor run that I started to warm me up- the idea popped again.
Basically I want to know about No Damage strats for bosses (Genshin, Alexei, Volf, Zedonius & Elizabeth [I don't think the rest is worth mentioning]). Back then I was able to ND most of them up to Mentor but in most cases it involved loops with the Flails/Lunar. Genshin was truly the only one that was fun enough to try and ND him fair and square.
So what I got so far (this is all related to my Mentor -and maybe MN too- runs because in Acolyte/Warrior is not really that hard to ND fights since you can inflict a lot of damage):
