Lvl 69? Impressive! Normal mode or Expert Mode? Also, what items at beginning? (sword, shield, staff)

I haven't tried that low a level yet, but I could probably do it. (if I restarted the entire ing game!)

I always have one method of fighting Sephiroth:

Normal Mode: (Lvl 100) Equip- Ultima Weapon, 2 Omega Arts, 1 Titan Chain 2 Elixirs, 4 Hi- Potions. Chose: Sword, then Shield
Expert Mode: (Lvl 74) Equip- same as above

Strategy- hit 'n run, he uses Flare as a counterattack to any hit; use no attack magic; equip MP Rage twice, thus, every strike will give you about 1 MP; after a 3-hit combo, back off since he'll teleport after a 4-hitter; dodge roll like crazy during meteor; attack him while he is summoning Heartless Angel (AKA Sin Harvest) and the spell will stop; Guard when he slashes (if you're fast enough) (NOTE: this includes his Omnislash, it can be guarded but he will keep slashing, no recoil); Curaga like a madman; and those black ball things (when he is blue) that folow his steps... just jump over them.
