Scales of the Two-Headed Hydra of Perennial Consumption

"The scales of a peak D-grade Two-Headed Hydra of Perennial Consumption. These scales retained their durability even after the death of the beast and have even been improved slightly by the Records of their former owner. These scales are incredibly durable, and if they are used as armor will make the equipment near-impenetrable by physical damage. They are incredibly hard to work with. Due to their nature, these scales have very limited alchemical applications."
