Hero Classes

There are 5 Classes to choose from in Puzzle Quest 3, each with their own Elemental Masteries and Spells.

All Hero Classes have the same Power and Vitality stats and they upgrade the same way for each Hero level regardless of the Class your Hero has. Each Hero Class also has their own class specific Spells.
See this article for a Spell Menu Overview.

Once you have chosen your Hero's Class, it can't be changed for that Hero, however, you can create an additional Hero if there's another Class you'd like to play.
