Golbez is the big bad guy so far in FF4, and now I have to fight him for the first time. This fight is...unforgiving, to say the least (horribly designed and meant to make people stop playing, more like).
At one point, he automatically kills Yang, Rosa, and Kain, before Rydia rejoins (with barely enough HP to survive an attack). Cecil and Rydia are your only remaining living party members, and all of Rydia's offensive ability heals Golbez instead of damaging him.
Golbez then proceeds to spam AoE attacks as fast as you get actions. If you use a phoenix down or Raise to heal a fallen ally, then they immediately die before you can take any other action.
How in the world is this battle supposed to be winnable? How can I get past this stupid thing and just get on with the game?
