Barbarian

Barbarians are native land dwellers. They make all of their own weapons, or aquire them on the battlefield. Barbarians use natural hides as armor and clothing, symbolizing their tribes.

Tribes are different clusters of barbarians, like a family, but aren't actually related. Similar to a Dwarven Clan.

They are the only class that does not immediately know how to read and write, they are illiterate. In their culture they do not need to know such trivial things. Instead they learn how to read the land.

Barbarians can fly into a rage, and it gives them boosts in their abilities. This gives them a bonus in strength, constitution and will. Barbarians that become lawful lose their rage abilities and stop being able to level up as a barbarian.
