Like other MMOs where you have to choose a class such as Human, Orc or Elf before you can play the game and have class specific abilities, There are no set classes in RaiderZ.
You are free to pick and choose from among different weapons and skills and their associated combat styles. Mix sword and shield with destructive magical forces, aid your allies with healing spells, or specialize in wielding two-handed hammers.
It is entirely up to you how you play this game.
