Super attack:

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. 

Hint: Finding Elements:

When looking for Elements on your journey, look for "bubbles"
shooting out of the ground. They resemble smoke shooting out of
the ground from a distance. When this location is approached, a
question mark will appear. Tap A, and the Element selection menu
will appear. Then, just choose the type of Element you wish to
build.

Hint: Element stone in the hay:

After you leave the castle, turn left and go to the stable with
the horse. There is an element stone in the hay pile.

Hint: Avoiding enemy magic:

There is little time to dodge an enemy spell in battle. Hold the
Analog-stick over while the enemy is casting a spell. By the time
the spell arrives, your character should be out of the way. Note:
Practice is required with this trick, since it does not automatically
work all the time.

Hint: Avoiding Earth-based magic:

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. 

Hint: Easy Zelse battle:

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.

Hint: Easy Boss battles:

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.
