Thumbs up to you man!!! I really like your strategy!! almost the same as mine and might be even better than mine. most faqs all over the net focuses on using hero trial or hero drink. some use GF's to absorb terra flare attack. some even think terra flare is a magic attack and uses shell. pretty stupid though. your right its a physical attack. though id like to suggest something to add to it. its up to you if you agree or not. Try using Auto-potion ability. but first sell all your potions and Hi-potions and buy a lot of X-potions. what happens is that when auto-potion ability triggers it uses the least potions available this is the reason you'll have to sell some weak potions so X-potions can be used instead. it gives 9999 HP. best to counter Omega's Megido Flame and Gravija or when your party is badly damage. saves time healing your party. Auto-potion triggers if your HP is bellow half of your total HP.
