All monsters including Julieta use the dreaded -HP% based attacks.
Because of that, all damage mitigating mechanics (Avoidability, Holy Magic Shell, Magic Gaurd, etc.) are circumvented.
and that is why I am basically saying "adjust it"
There are lots of problems in Monad: full of glitches, inconveniences, visual stutterings, and many others. I am just pointing out a couple of those in feedback section. I don't mind how all of my skills do even less than 10% of what they used to do or how mobs of monad do -HP % damage with 100% on-hit. It is a story walkthrough, and I have no problem with that. However, boss run is a different story.
