Easy level up
Use this trick when you have few experience points but need a quick level up, or just want to get ahead of the opponents. Take a Siren, Wizard, or Magician with any attack spell. Go into training and line nine people up where they can all be hit by the attack. Keep using the spell until everyone is "dead". Note: Everyone should die at the same time. You should get about 92 exp. for killing nine people at the same time.
