Quest 64

Run towards any monster that uses Earth-based magic while they are attacking. They always miss if Brian is close enough to the monster. Since their stone attacks are more powerful then their physical attacks, this strategy will also conserve hit points.

Every time you get the option to increase your magic, always increase your water element. You will get the best spells. These spells are a necessity to get early in the game.

If you want a very high Agility stat to avoid enemy attacks more often, there's a very simple way to do it. First, head to an open space - in Brannoch, Melrode and the path along Melrode Monastery work nicely - and start rotating the control stick so that Brian will continuously run in circles. While you're rotating unplug the N64 controller you're using. If done correctly, Brian should still be running in circles. The more you run, the more Agility you gain. With this method you can leave the console on and gain a nice amount of agility without any work.

Before facing Bosses such as Guilty, Begis, or Mammon, collect as many Dragon potions as possible. During the battle with the Boss, use the Magic Barrier spell under Earth magic. Brian will be protected against magic attacks, allowing him to attack the Boss without harm. Use the Dragon potions to restore MP to cast the spell again when it wears off.

When facing Zelse in the battle for the Wind Jade, Brian can avoid his second attack by standing six or seven steps away from him. When in this position, Brian will be able to easily outrun his attack.
