(Metalskin) Armored Demon Arnold

Lore
Regardless of how much it consumed, the cocoon demanded more sustenance. Its usual diet could no longer satiate its intense hunger. More nutritious food was required, so Arnold sought out the enchanted "Mendersprout." With its abundant magical essence, it was the perfect meal for his charge. He set out to the Mendersprout fields, prepared to fight any who intended to hinder his progress.
