Parmandur
Book-Friend, he/him
I'd say even in 2014, the Barbarian has a preternatural edge, at a minimum (a Champion Fighter being able to get off 8 Greatsword swings in 6 seconds is pretty astounding, too, I suppose).Barbarian Berserker fits the paradigm as well. The Primal Knowledge ability doesn't need to have the appearance of being "magical." There are no actual spells or visible effects that suggest that it is. It can just be a willful focus of "I am so infuriatingly, stubbornly, persistent and sure of myself that I will succeed, that I have an edge at actually succeeding."
