I think that's its name. Optional dungeon's optional boss, only available after beating Final Boss. Level 200. Whoot.
1st playthrough. Normal Difficulty. Boss comes in 6 parts, with the Head at 1,000,000 HP. Other 5 parts range from 270K to 620K HP. The wonderful thing being, the Head can revive any dead body parts (about 50% HP?) infinitely. And you can only attack the Head efficiently if the Body (420K HP) is dead. The other body parts also can cast Poison and TP Poison -_- Of course, their Attack and Defense stats are nothing to sneeze at.
Party members Level 129-130. All skills/artes learned. 2-player. All but 1 had 9999HP and 999TP (no stat item, e.g. Verbena, used).
Members:
Masked Diver Flynn
Ponytail Yuri
Sad Magical Girl Estelle
Snowman Patty
It took close to 76min D: I played Flynn and sometimes Yuri. Bein was playing Patty, but we quickly saw that AI-Estelle wasn't too helpful, so he switched to Estelle while I analog-controlled Patty to cast Critical Moment at the right times.
The strategy became kill the Body, attack the Head until Body revives. Repeat. D8 The other limbs died (collateral damage...) and revived several times too. Mostly, we gave up on removing Poison. Estelle had her hands full keeping people alive. Patty attacked on her own until I ask her to cast Critical Moment to fill the Overlimit Gauge. Flynn is used for physical attacking until Patty charged the Overlimit Gauge so that we could Mystic Arte. Yuri attacked on his own, and died very often (he doesn't have Flynn's Defense stats ._. I tried using him awhile. Couldn't keep him alive if I were to attack), and was mostly in charge of activating Overlimit since he could share the Overlimit with others, and Flynn had a habit of Skill matching his Overlimit without spending the Gauge.
Yuri + Flynn's Mystic Arte = love. Not only is it pretty, it hits all enemies for high damage (that's how the limbs kept dying I suppose) and was the top contributor for damage. It requires both to be in Overlimit 4. Not too easy. But with Patty randomly charging to Overlimit 8, and Flynn's unique skill, we pulled it off at least 5 times.
Yes, Estelle was the one short of 9999HP. And yes, that's 1.8 mil EXP, thanks to one of Patty's random Critical Moment outcomes - 10x EXP. All members soared about 10 levels.
That's 114 grade deducted for Damage Received -_- 69 grade is for triggering Fatal Strike Chains. 60 for killing the boss(es).
Player-Controlled character KO -36 (purportedly 36x1.0) D: AI-Controlled character KO -24 (purportedly 96x0.25!?) D: Top contributor probably Yuri. Burst Artes 67x1.0. Mystic Arte 31x1.0. Top contributors Yuri, Flynn, and whoever shared Yuri's Overlimit-activation. Fatal Strikes 26x1.0.
Pretty cool~ will try a different team next time.
