RE: the 7th saga
Beating the seven apprentices
All: Buy a B.Power and B.Protect, or Runes, and don't randomly pick a fight, fight them only when they are in your way.
Kamil and Olvan: Use the Water Rune or Potion2 and wait out their castings of Fire2. Kamil won't even use the Star Rune if he has it. When they attack for at least 4 rounds, then you counter and slay them. Olvan is smarter, and uses runes and other magic.
Wilme and Lux: Wait out their magic (which won't take long) and then attack. They are weaker attacking, but have more defense than Kamil and Olvan.
Esuna and Valsu: This is tough, they have at least 80MP, but only cast Ice1 after putting their attack and defense up. Their Ice1 is tough enough, and they won't let up. With the Sky Rune, their murder.
If you agree to the tyrant's with the Star Rune's idea, you can go in and out of the castle freely, and you can change your mind and kill them.
Beat up Brains and S.Brains for easy experience and GP. They also give away recovers, which refill HP and MP. N.Brains, however, aren't worth very much.
Only fire can harm Monmo. By the time you get to him, you'll have the rune that can restore MP, so pound away.
You can beat Lejes easily by having Defense1, or the Star Rune. He always uses Defense2, then he attacks if it worked. He won't even heal. If you can keep your defense up, he's dead.
