Warrior
Warriors have higher health and stamina, however their strenght also makes them slower and clumsier.
Rogue
Rogues are fast and have high stamina and speed which makes up for their lack in strenght and health.
Mage
Mages are glass canons which put all their efforts into spells. This means they slack on everything else.
Hunter
Hunters are well rounded fighters that focus on everything of their skills. No strenght or weeknesses.
