Mythos: Song of Sword and Wings of Lost Paradise Final Boss Help

[nintendragon64]

I've been playing on mobile instead of Steam, but this is the most convenient place that I can go for help.

Does anyone have any advice for the final Mythos boss? I'm not even sure what kind of team to build -- I usually just use stance-boosted AFs, but that's not enough here.

I have had some success using an Earth stance team with Melissa, as Myunfa's passive team heals really helped. I even made it to the 25% HP stopper (though I did have to buy a few continues in the process ), but then I hit a wall when he regenerated his wings.

One place I know where I can improve is with Grasta, as I've only barely dabbled in them. I have collected a bunch of T3s from the Present and Antiquity Garulea ADs, but I just don't know which ones to invest resources in beyond trying Power of Quake ones in my last run.

I'm just looking for any guidance on what direction to take in setting up my team.

You will be fine as long as you have decent armor and weapon. Grasta not needed if you have good team. It will help alot if you have them.
Earth:
Melissa, Diedere, Violet, Velvet |Myunfa, Any debuffer or healer

AF kill the wing.
Bring in Myunfa then rotate your int debuff till hp stopper. Save your AF till then.
The 2nd wing summon: bring in Myunfa then af the wing.

Another team alteranive is Tales & Persona 2nd team.
There is plenty video in youtube you can ref to.

Use debuff, anti light armor, type resistance and healer.

Edit: My previous team was Guildna, Melina ES, Morgana, Ewan AS , Yipha and Mariel

First turn just debuff.

2nd turn I switched guildna with Yipha to get blunt zone and switched Morgana to Mariel,

3rd trun with enough debuff, my Ewan AS deals tons of damage and also use Mariel type resistance shield.

After my AF bar is full I spammed all my skills and boom my ES Malina summoned a giant fist down the boss throat. ( My Ewan AS is my main damage dealer at this point.)

That Earth team is actually pretty close to what I was already doing -- I had Nagi and Toova in place of Velvet and Violet (and Mariel AS as the healer, BTW). While I wasn't looking for Int debuffs at the time, Nagi's Calamity Axe does include one. But it didn't seem like the post-stopper Earth AF worked as well as the Melissa's Flash one.

I decided to try a Slash team (Melissa, Milla, Miyu, Nagi, Radias, and Mariel AS), as that stance works with Melissa and Milla, Miyu, and Nagi all have attacks with Int debuffs. And I actually won with it! I mean, I still sadly had to buy a few continues, but fewer this time. Thanks for pointing me towards the debuffs; that's something I often forget to take into account.

My two cents:

Add in the free IDA 3 character with the -35% int/+35% pwr skill to neuter the boss.

Pop in a stance after Melissa's expires, except the Magic one for further nullifying and build your offense around that. If you use Melissa, I recommend Slash, which you also have free options.
