I’ve written up the major nations for Dinosaur Riding Barbarians, but I don’t think I ever posted the class concepts. Let’s go ahead and fix that.
Beastmaster
The Beastmaster commands a small pack of dinosaur minions, usually velociraptors or deinonychus. In addition to the obvious benefit of leading something like a half-dozen allies into battle, the Beastmaster can set up pack attacks. For example, when one of the Beastmaster’s pets is adjacent to an enemy and another pet charges from the opposite direction, the charging pet pounces and gets extra bonuses to attack and damage, if three pets have a single enemy surrounded, they each get heavy bonuses to their attack rolls, and so on. The Beastmaster himself has respectable attack and defense, and when he has all of his pets available and fighting effectively, he can deal more damage per round than any other class (counting the pets’ damage).
