I beat the boss TAHARKA (he's the one after u get the 4 mirrors in disc 3) With just melee attack because my guys had no mana (MP) I used no trances (no MP) and no attacking Items. I justed used Hi-Potions and the auto potion Ability. It was easy because TAHARKA doesn't deal that much damage. Try it ^^. <~~~~Zorn or Thorn lol
