It was striking to me that the creators of the series installing small innovations in each game. This time you can (Paladin z. B.) update at specific points on the character of a standard class (z. B. Krieger) on a prestige class. The prestige class has special properties that are very useful, especially in boss battles. Unfortunately, any prestige class starts again at step 1. It is, however, much faster upwards, as in the standard classes. In any case, you should at least update his hero on a prestige class. And one more thing: As a casual player I can recommend the products featured on the website videogame zone dot de walkthrough very (!). Without the advice on this site I would not have won the final battle. My team had the following at the end of stages:
Paladin (Level 38)
Martial artist (stage 45)
Priest (Level 43)
Wizards (Level 43)
