Path of the Otomi

The Barbarians of the Quetzal Race have learned to harness their internal rage and apply mental and spiritual defenses as well as physical ones. Obsidian was discovered by the Quetzal race to be a material that ignores any resistances or immunities when used with a weapon. The Quetzal Otomi became the masters of using this type of substance both offensively and defensively. The Quetzal Otomi and the Quetzal Dragoon are the pinnacle of warriors of the Quetzal race.
