I played the entire game in English, absolutely loved Ophilia, Olberic and Primrose voices. But when I switched to Japanese just for shit and giggles, I was blown away. They sound so much better and serious.
This final boss is way too hard for me. It took me hours to defeat the first phase only for the second phase to absolutely destroy me. It doesn't help that I have to fight all those annoying bosses again and can't save after that. This is really making me not want to continue. I have OT2 as well and really want to start playing it.
My team is mostly lv70+ and I think I have decent equipment/skills.
Team A:
Sorcerer Therion with all the fire damage boosters.
Starseer Cyrus with 2x elemental augmentation
Cleric Primrose
Warrior Alfyn
Team B:
Warmaster H'aanit with all battle tested equipment
Dancer Ophilia
Apothecary Olberic with Last Stand Build
Runelord Tressa
Not sure if this team sounds bonkers, but Team A is really helping on the first phase. Everyone is 70+ except for Ophelia and Alfyn who are below Lv70.
EDIT: I tried 3 times today and FINALLY GOT TO DEFEAT PHASE 2!!! Thanks a lot for your comments, I am so happy
