I beat Meredy, Farah, Garr and the whole Advanced Class at Mania Mode

Seriously All By Myself
but you have to really be stacked on every item that heals when you get to the expedition match expecially Life Bottles

I didn't really care about what items I put on Kratos and Sheena accept with their latest stuff and gave them 2 thunder capes, Sheena the other Element Circlet:(guard fire, water, earth, wind) Because Without Raine I didn't know how I would have made it through the matches.

I attached Raine with the Spirit Robe, Element Circlet, Penguin Gloves, Reflect Ring, and the Persian Boots. Which made her almost Invinceable against meredy spells and Garr's Scissor Slicer. And I was resistant against every element.

"She Would Absorb": fire, water, ice, earth, and wind(Mainly heal her when it hits her)
"She Would Resist": lightning, darkness, and light(Would do no damage against her)

Raine Ex Skill:Concentrate

Sheena Ex Skill: Dash, Spell caster Of course to cast out the summon spirits. And gave her the jet boots and mystic symbol when ever raine dies and I or her need to get away from the monsters and revive raine quicker in the regular advanced classes.

Kratos:Concentrate- Before sheena revive me I tell him to use first aid on me before I die, and hold down L So When sheena revives me I let go of L I will get health already.

I couldn't believe it when I did it to and I almost died in that battle with raine at 1HP when she hit the ground I hurry up when I got up and gave a life bottle to sheena, and told her to revive me when I died and I gave a life to kratos (Avoiding gettting hit) for him to heal me with first aid and with a lemon gel. I WAS BACK IN THE GAME.

Hope I was helpful!
YOU DON'T BELIEVE GO AHEAD AND DO IT YOURSELF AND WATCH WHAT HAPPENS. Remember if players are with you Put "RAINE" As First Player so that every one can see the field while your in the back spellcasting or healing. This was in the gamecube version of US.
