I fix it! XD
fight for your life, do that as hard as you can. He scales to level so if you bring a massive party, your in for a doozy.... If your going solo, this is going to be one of the hardest fights ever, and please refer to other guides for detailed info on this boss. Prepare with every invintory extend upgrade avaible in game so you can carry every phenox down, reviver seed, max potion, and whatever else you find nessary for restoratives.
First (time out!): remember the old kingdom hearts thing? With the clock? Yep, a rematch. Every time the clock spins around and hits 12, he casts a high level spell like ultima,elemental flare, omega crush, and the like. Use stop or if your not a mage, stop watch items, and keep the clock from moving as often as possible. If you recruted a time mage, use rewind, extend, stop, and slow on the clock to keep it from hitting 12 for max effect.
The hat (close combat): it hits, hard, often and fast, only fighter like charaters with high defence and HP, and rouge like charaters with great dex. and agility to dodge should even get near. Make sure you either have no weakness at all or are resistant to all elements, otherwise the darn A.I will use scan and find out what your weak to and use an elwmental knuckle attack to do massive damage. [resistance to poision, payralize, break, and stun are sujected for a win, all else will fail.... In close combat.
The monster of a man (magic ahoy): here we need mages of all types, or a single mage with massive amont of power [if your going solo]. time, red, blue, white, and green magic are great assists for this match. Support and do nothing but support if your green, he has banish and clense so your buffs are gonna get wiped early and often. Red, just hammer on him with offence magic, nothing more or less. Blue mages concentrate on debuffing and hitting him with status effects, the others will need all the help they can get with hitting him. Now, to cover for your fighters up front, use redirect spells, or reflect on them if your nutts enough to have crap rebounding everywhere, to keep his high level magic from one shoting the front. He has resist 20% to all so just use either multi attack, or non-elemental attack magic if your going that route.
last {the liquor of the devil}: now for the important part, as soon as the scarf/hat calms down ande he pulls out a potion after the talk of 'being the best fun I've had in some time' ,shoot, hit, do what ever to stop him from drinking a full heal potion.... if he drinks that, your hosed..... No ammount of items can get a single team ready for a round 2 with this guy...
