Legionnaire Scout
Most tales of the dwarven Legion of the Dead are likely minstrels' fabrications, but the trail of darkspawn corpses that the Legion leaves behind proves the efficacy of their training. Legionnaire scouts often travel ahead of their companions, and have consequently become renowned for unusual hardiness, able to survive battles that would kill any other rogue.
