Ok to review in a whole
I’m not stuck on a particular quest, essentially the problem I have is that it’s pretty much the rule governing all bosses to chain bonus actions like crazy whilst having too much attack power
I find element advantage to be useless due to the fact that bosses will often kill in one hit, it’s a luck of the draw if it decides to take you out or not
Grinding helps, as well as ‘bane’ attacks but again you can get in so many hits before the boss chain attacks again. Flash bomb as well as stun chance attacks help in my opinion but not enough to push back the boss for long unless you spam them like crazy and get enough stuns
My own partial strategy has been to go in with a void ability (one that caters for the boss type) and use it on my strongest party members
