Welcome to Gaia! ::

Whoo! I did it finally. After, like, several months 'cause the game was left to the side for a while. Heh. Well, I technically beat him twice, but the first time I beat him his HP was completly depleted and he still kept goin'. And I, of course, got mad 'cause he was still able to kill me, so I slammed the paddle on the floor and I accidentally got my friend on the foot... /)^_^;

Anyways, did anyone else besides me have this much trouble with him? Mind you I was only at level 77 when the strategy guide recommended that you be at least at level 80. But big whoop, 3 levels. xd

Lucky you. The second time I depleted his HP, I had no elixers and no Hi-Potions, and no MP... And pretty much 1 HP left. It was pretty much just a little sliver in the HP guage. I got hella lucky, that's all. There was really no skill. xd

Yeah, my eyes were wide open when I watched him fight Sephiroth. Especially when he beat him with that much health 0.0

Final Form is only avialable after the showdown with roxas and is random for the first time. just keep transforming into master and you will get it eventually, you will have more chance of getting it when fighting an organization member mrgreen

ultima weapon requires the 7 orichalaum+ and an energy crystal.

orichalcum+
Hundred Acre Wood- Pooh’s World-finish
Space Paranoids- Tron’s World- Computer Mesa
Olympus Coliseum – Goddess of Fate cup
The World That Never Was-Brink of Despair
Twilight Town-Sunset Terrace
Atlantica-Finish
Obtain All 50 Material Types

Energy Crystal
Bookmaster-heartless
best place to find them is the radiant garden right outside merlin's house

No offense, but Sephy was easy. And the reason he had a silver of HP left is because you have to finish (like all bosses) with a finishing move. If you have Beserk Charge equipped, then it disables the finishing move while in MP Charge.

Sorry to say this, but you need WAY more than just that for the Ultima Weapon. You need these following things:

Moogle Shop Synthesis
Ultima Recipe
Orichalcum+ x13
Orichalcum x1
Mythril Crystal x1
Dense Crystal x1
Twilight Crystal x1
Serenity Crystal x1
Energy Crystal x1

Yeah... I'd say that that's a lot more than what you said was needed for the Ultima Weapon.

getting away from the ultima weapon for a minute...Sevvi wasnt hard in KHII. i beat him at lv. 40 on proud before, and i know people who have beaten him in the 30's. it just depends on how fast you can move sora out of the way and how many times you can hit him. as long as you hit him to stop him from doing "sin harvest angel" then your pretty much all set; his other attacks can be blocked with the keyblade or, like the fire thingy, just run away from. just have lotsa elixers in case you cant hit him fast enough to stop sin harvest angel 3nodding and, his VA sucked. horribly. it makes me sad when lance bass makes a good VA for Sevvi O_o

I just waited until he used it and used a High Potion an instant before it was cast, so the delay of the item hits just after the "Sin HArvest Angel". 3nodding
