Labyrinth of Galleria: Lingering Memory (Spoiler warning)
So I dunno why the start of the recording decided to have a stroke
Difficulty: 6.5/10
Nachiroux has a respectable 575,000 HP which isn't the highest in the world but her defenses don't suck so she won't go down without a fight.
She has all the elemental spells and the ability to inflict status effects like dizzy, abyss, and startle. She resists physical attacks fairly well but elemental attacks do basically not a thing to her.
That being said you'll still want to have a strong mage because after 3 turns she'll instantly summon 4 buffed magia-gias to chain together Magic screen nukes but with Lamp Fog 4 you can kill them quickly. That being said don't take too long cause she can just summon them back.
This fight isn't so hard that you need a perfect team to win but it does exist as a warning that there's gonna be some tough fights once you go in.
Also this is the last time in the game dance of evermore plays. Enjoy it.
