Defeating the White Dragon:
     First  beat  Brimhild,  then  you  will  fight  against the White
Dragon. To defeat the White Dragon, you need lots of Magic Potions and
Grilled Eels (30 each recommended if Ylenne is over level 20).

     While fighting try to stay out of his meteor attack's range. When
the  White  dragon does not move, stay outside it. Line Ylenne up on a
straight  line with the White dragon, go to little closer to him, then
attack  him  with  Ylenne's  Hell  Fire  attack. (You need in range to
damage  the dragon.) If you need, use your other heroes to refeill her
MP. In this case Ylenne can use Hell Fire attack repeatedly.
