Once you hit the Max Level, you have a option to Prestige your class. If you choose to do so, you will loose your level, armor, and weapons. On the flip side, you will gain a New Class, stronger spells, diffrent spells and diffrent gameplay. Here is the list of the Prestige Classes
- Warlock - Necromancer
- Warrior - Blade Master
- Rouge - Assassin
- Hunter - Beast Master
- Shaman - Avatar
- Mage - Arch-Mage
- Druid - Arch-Druid
- Paladin - Knight
- Priest - High-Priest
The Death Knight won't have a Prestige Class because it's a Hero Class
Prestiging your Class can only happen once per Charature but you will always have an option to Prestige your Class from your Class Trainer.
