Iseria Queen

Crafting Immunity Pills for Iseria Queen - Compound 2 Artemis Leafs until you get the Immunity Pills if you want to save accessory slot for preventing ailments. You can use that item in the upcoming fight to be immune to ailments.

Formation Manual "Unyielding" (Upper Guard) for Iseria Queen - Defeat 5 enemy leaders Beginner Mission and claim it to unlock this formation. If you keep Claude alive you will have ailment imunity. I used this approach. It also raises your GUTS for 30% and Defense 50%, so it will help with the upcoming fight.

Stock up on Holy Mist healing items and resurrect potions. You can craft them using Compound and replicate easily. You can also switch to Earth difficulty if you want, it makes the fight a bit easier. The equipment you can setup as for Maze of Tribulations fights, just add some better armors with perks if you have. You can check the video for details if you want.

To call Iseria, perform The Devil's Aria with Lv10 Music skill to fight her. The fight itself is really similar like with Gabriela, but harder. I didn't strugle as much, I was level 255 and my equipment was solid, so this end up being a short fight. Still, use Claude to heal and try to survive with him if you want to keep the Formation Bonus, you need them. You can use some attribute boosting spells with Rena to raise your attributes, so do that at the start and just heal when needed. Her spinning move is the worst.

Gabriel without limiter

To unlock Gabriel's full potential, you need to watch PA with Philia #1 in Kurik (MISSABLE) - This PA is a pre-requisite for removing limiter for Gabriel, if you missed this (before Kurik gets destroyed), you can't do the Gabriel fight without limiter. You will have to start a new playthrough if you missed it.

Then, watch PA with Philia #2 in Centropolis (MISSABLE) - If you didn't do the first PA with Philia you will not get this one. This will be available in post-game in Centropolis, just enter the offices. Now you can go to the top of Phynal tower and defeat Gabriel again for the true ending and different scenes a bit.

He is much easier than Iseria if you ask me. Just heal and do the best you know and can. The key is healing and attacking when you can, but with maxed out level and stats he is not that hard.

Ten Wise Man Return Group arena challenge

The Ten Wise Man Return Group Battle Arena challenge (The Wise are no match for me trophy) - Load up your clear save after defeating delimited Gabriel and do this to unlock the trophy. It's easy, the only issue is the last fight really, the rest of the fights are easy and you will get through them fast, then you need to defeat Gabriel delimited and you are done.

With this, the hardest challenges are done. There is no more content after this, you can finish the whole arena and mop up what you miss and start a new playthrough if you need to do so.
