So I just beat maat, mostly followed this excellent guide, however would like to detail my experience.
As a tarutaru I was concerned about low vit/hp, and so borrowed some gear from a friend.
Range: Respective songs instruments.. (read below)
Head: Emperor Hairpin
Hands: Battle gloves
Legs: Crow Hose
Feet: Bard AF
Earrings: Dodge Earring (x2)
Rings: Sun ring (x2)
Waist: Life belt
Back: Amemet mantle +1
Sword skill: 210
Evasion skill: 199
Parrying skill: 140
Singing/Wind/String skill: Capped
Food: Tavnazian Taco (x1), Selbina Milk (x10), Hi-potion (x6), Icarus Wing (x1)WARNING: DO NOT MACRO IN INSTRUMENT CHANGES FOR DIFFERENT SONGS
So I just copy/pasted my normal macros and used those. HUGE mistake, of course every time an instrument changes, you reset TP. Ended up getting only 1 WS off the entire fight.
Important to keep paeon up the entire time, because even with all my evasion gear, he was still slapping me about, paeon saved me.
Close fight, managed to win on 130hp following his dragon kick.
tldr, Camy's guide is great and if followed should be an easy win. Eat taco, use icarus wing, soul voice double paeon. Start with finale + elegy, finale when he buffs, drink selbina milk when he finale you, WS when available. Don't panic from the occasion, and don't let the music freak you out.. it always makes me nervous..
