Defeat the Marble Aggelomoirai
This is a true skill and gear check kind of boss fight. Before this, you could get away with mediocre damage output and decent combat prowess. Now, you need both to do well. Skill can win the day, but that makes for a long and taxing fight.
If you do not have good weapons and at least a set of gear on each of your party members, then take the time to get a gear set for each character, and level up their skills as well.
Phase 1: The first phase of the fight is frustrating. The Marble Aggelomoirai is completely immune during this phase. So, take out the four appendages around the battlefield.
What makes this annoying is that the appendages keep shooting projectiles at you from all four spots. There’s a lot of cheap damage here, but try to focus on the one you’re dealing with first.
When a red spot appears on the ground below you, move out of the way. These end up being projectiles that leave corrosive darkness on the ground, which deals damage to you if you stand in it. Oftentimes, they shoot this at you, and since you’re standing next to one of the appendages, you end up having to retreat for a bit until the corrosion disappears.
With each felled appendage, Marble Aggelomoirai staggers more and more. After taking down all three, the core appears from Marble Aggelomoirai. Attack the core, using all of your cooldowns. If all goes well, you can get through the health bar before the stagger times out.
Otherwise, just repeat the process to stagger the Marble Aggelomoirai again, taking out the appendages one by one. Thankfully, this time the boss only has two appendages appear.
Phase 2: For phase 2, the Marble Aggelomoirai takes a humanoid shape but with six arms. Right away, it jumps into the air and throws a spear down at you.
A lot of her attacks are aerial. So, it’s best to wait to use abilities until after she finishes her combos and attacks.
Eventually, her arms into wings and dive bombs you a couple them.
After that, she goes high into the air with a choreographed drop that sends a shockwave across the entire map. This is hard to dodge the first time because the visual cue is different from every other one you have seen so far. Right before she drops, the vertical beam gets bigger and pulses bright. At that time, jump to avoid the shockwave.
She also does a melee combo with a spear. After three swings, she opens a window for you to counter. Hit her with an ability to crush her stagger bar some more.
Shortly before you break her stagger, she goes up into the air again and bombards the field with blight arrows. Keep moving and avoid the red circles on the ground.
It’s also worth mentioning that if you die at any point in this fight, whether in phase one or phase two, you will need to start the fight again from the very beginning.
Beating the boss finishes Undying Cinders main quest in Arknights Endfield.
