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.
