There are 12 different classes. The choice of class determines which spells your character will receive, as well as how much characteristic upgrades will cost. The class names are inside jokes amongst the developers, often (but not always) referring in some way to the abilities of the class. For example, the Xelor class which uses time dofus kamas magic in combat, derives its name from Rolex, a watch manufacturer.

Pandawa’s pint (Padawan or Panda Warrior) - While sober, they’re a support class, carrying allies around the battlefield and lowering enemies’ elemental resistance. When drunk, they become formidable close-range fighters, with reduced movement but powerful attacks and damage reduction. This class is available only for paid players (pay-to-play or p2p).
According to a post on this topic on the official forums, Feca, Iop, and Sram were the first three classes created, so the developers named them after their favorites among the various snacks they enjoyed while making the game, and the names have nothing to do with the classes themselves.
