Class

From NecroWiki

There are four pure classes available here at Necromium.  Those classes are:
Warrior, Thief, Mage and Cleric.  It is advised that you choose one of these
initial classes that best suits your playing style, as your decision will
influence everything that you do in the future.
When multiclassing, your learned biases from years of training in your 
original class stop you from choosing another one of the four pure classes.  
Instead, you have specific subclasses to choose from.  Listed below are the 
sublasses and the pure class that they represent.

Read HELP MULTICLASSING OR this article for more information on the multiclassing process.
