Another Eden Bladelord Galdmagid (Expert Difficulty) ft. Main Story Characters

So this boss due to how it works makes it impossible to clear on master difficulty without SA aldo for dps and SA galliard for survival (if wondering I refuse to use SA system myself for anything). On master difficulty this boss gets its aura at start of battle with 50% damage increase, barrier pierce, and priority every move, along with environment that increases its physical crit rate and applies 3 stacks of slash break on allies and enemies every turn. Even on expert difficulty without the aura activated at start of battle this boss still does extremely high damage on first stopper attack. Stall is also not an option for this boss since it gets 5% power from stacks every turn and at last phase it even gets all 20 stacks instantly (permanent uncleansable 100% power buff..)
EDIT: So after randomly finding this video here: • 【アナザーエデン】 ストーリー3部後編 剣帝... I learned that there is another method for surviving this bosses attacks and is by letting one character survive with 100% physical res then reviving other allies after. I never would have thought of using revive normally, I initially tried going the 100% physical res route but with galliard and could only get to 91%-94% physical res which isn't enough for him to tank all 3 hits and the fixed damage before party dies. Even if video uses SA aldo dps very confident it is doable without his SA for dps unless boss has extra gimmick as fight goes on.

I'm still glad to see that Main Story characters can still be usable in Master Difficulty even without SA

For this fight is basically impossible for non SA story clear here, this is on expert difficulty. Wrote details for this in description, this is doable on master but needs at least SA galliard for survival and maybe SA aldo for dps.

@@c0ffeedr1nker48 Oh yeah, I mistake read this as Master, even though it is Expert

[@khoonkiatong7522]

just curious, why do u refuse to use SA?

[@c0ffeedr1nker48]

Lot of issues with system itself even if free characters you can get without them. And make stuff way too easy like taking out entire phases of fights before enemy even attacks while not getting punished in majority of cases.

Aldo no stella awakening?

[@c0ffeedr1nker48]

Yep, like mentioned in description I refuse to use SA system as a whole.
