you've got to be kidding me... Though i dont use armagedons fist, it still can't kill omega that easily... he will still around 8 to 10 turns left before he will cast terra break on you, and if you dont have defend or holy/hero then youre practically screwed. Ultimate weapon may be fast but his moves are not as deadly... except for light pillar which hits one person for 9999 damage... however you can counter it with life, full life, phoenix down and then cast curaga or restore, or elixer etc...


about the junctioning its very hard (emphasis on hard) but possible to beat omega/ultimate weapon without junctioning magic to your stats... if you have squall even without his ultimate weapon, simply use rough divide all time, with aura on all your characters; omega/ultimate weapon being meltdowned; zell doing armaggedon fist, and rinoa in angel wing form, having no magic in her stock except meteor then its possible to win, if you defend at the right times, and have a lot of life items... (however a challenge which includes no magic use especially aura and meltdown would be even more harder)

I don't use armagadon fist but another combo involving heel drop, and booya, and an ocassional punch rush when starting...
