If you are one of the gamers stuck in the battle against the Dark Elf, and you are wondering how to defeat it, because he simply causes 9999 damage to each one of your party members killing you without problems, it means you forgot to trigger a cut-scene in Toroia Castle. So, go back there and search for a room where Gilbert in on a bed resting, a scene will trigger. Now go back to the Dark Elf’s lair and fight against him, now he won’t hit you physically and cause you 9999 of damage, instead he’ll use magic against your party, nevertheless you will lose, there is no other possibility, but this time, you won’t get a GAME OVER instead Gilbert will help to battle the Dark Elf with your “metallic” weapons. So be sure to re-equip everybody with their metallic equipment and fight the boss.
