Defeating the Dark King:
Keep using cures on the final Boss to hurt him. Use it on him approximately twenty times and he will vanish into thin air.

Use the cure spell on him, but do not have Phoebe use it. Have her cure you, and then have your character cure the Dark King. This attack will do about 14,000 damage. However, Phoebe cures the Dark King 12,000.

Exploding doors:
When you get the Mega Grenades from Fireburg and you need to blow up a door, you do not need to find a chest that contains bombs. Instead, just go to a door and press A. Note: This trick only works with Mega Grenades, and not Bombs or Jumbo Bombs.

Unlimited Cure Potions or Heal Potions:
In Foresta, you can get three Cure Potions and three Heal potions every time. Keep entering and exiting of Foresta as many of those potions as desired. You can actually get unlimited Cure Potions from any house, such as the Elixir girl's.
