Death Stench Muscle

Armor that carries one to death. Otherworldly light and always incredibly cold.
Armor made from Elder Dragon bones and from sinister cloth that explorers bring back from unexplored lands. As its name says, it carries a smell of "death." It is sometimes decorated with the skull of a long-dead master, and many hunters loathe using it. Because it lets the wearer get close to monsters without being noticed, some have called it armor possessed by the god of death.
