The warrior ways of the Dothraki might make them appear as simple barbarian
savages, screaming into the sky as they charge into battle. And many
commanders have underestimated them because of those stereotypes. A Dothraki
will spend more time on their horse than they will off of it, and with that
experience comes skill that regular training will never achieve. Despite being
unarmored, it is still difficult for a trained swordsman to land a significant
hit on a mounted Dothraki.
