Hardened Skin Technique

Monks of the technique of hardened skin mastered the dominions over their muscles and skin, becoming more resistant and stronger than the natural. Using their Ki they can not only better resist damage but also deal massive damage to their enemies with fewer unarmed blows.
They follow the paths of the master Lupo Fend, a human monk who, after being a slave for years, ran away and perfected this technique during her life working in a guild, the White Raven.
She became a champion of Khorhonen, God of Strength in the plane of Caos and was the only person who hold a fight alone against one of the demi-gods of Thraren.
