They can be barbarian brutes, skilled mercenaries, or refined knights. But all of them have something in common: they can use the heaviest armor and weapons, and they tend to get into a mess very often.
Warriors have the highest Health' of all classes, and a decent damage progression. Their skills are often defensive, and that combined with their heavy armor makes them able to survive direct combat with many monsters at once. Well, at least better than others do!
When needed, they can sacrifice some of their defense and use two-handed weapons, which are great against high-armor enemies. For the most part, only warriors can use them.
Base health at level 1: 45hp
