It's not, we won our first try with Fo/teX2 and BR/HUx2 Neither of our buffs were anything special above standard. but i'll admit we BARLY won it, he died literally as the timer hit 0, honestly thought we had failed.
Much like the original it just takes decent gear, i guess this is why they made it 80/80 to give maximum damage chance, i wonder what his HP is.
I'm slightly disappointed it's the exact same fight, in the exact SAME way, just different texture (and skip straight to last phase). then again, sega does reskins and recycle same move sets..a lot so, i'm not surprised.
Now that i think about it, what are the quad weps good for, are they even worth it? i was hoping they were stronger version from the zen ones . but they aren't i didn't really see the point in adding flashy version of the same weapon, why does sega do this.
