Quest 64

Get within striking distance of the staff during combat. Select any spell, then press A. This will result in an attack with both the staff and magic spell in a single turn.

For the best way to raise defense find a monster that uses spells like Windcutter Lv3 or Homing Arrow Lv3. In other words a monster who uses lots of individual attacks in one turn. Defense is accumulated more by how many times your hit, not how great the damage is. Now just simply let this monster attack you, you leave it alone and let it do its thing. While its hacking away at you cast healing spells to keep yourself from dieing. When your health gets too low kill the monster and repeat.

Go to the password entry and type Q in every space.Then it will say the password was invalid. Well it's not invalid! Go back until you find a debug option. There, you will find a cheat for invincibility, infinite ammo and more.
