hello, It is my first play of FF VI and I was wondering how can i kill Doom Gaze, because when i enter a battle he always casts L5 Doom and all my Characters die instantly?
(my characters are lvl 70)

another question, what happens if i kill all 8 dragons?

and, If i didn't get Atma weapon in a world of balance, is it a big loss that i don't have it?

thanks for answers ;D
