Exemplar

There are some that never strayed from the initial allure of being a fighter. Instead of specializing, they perfected the general practice of fighting to a divine standard. Exemplars are as well-rounded as fighters can be. Unburdened by identities beyond being able to lift a weapon and strike true, Exemplars, as their name would suggest, excel at everything. If there is such a thing as a jack of all trades, then these fighters are the masters of all trades.
