Inventory description[]
"This colossal greatsword once belonged to Sir Francis the Resolute, a martyred hero of Tristin who later arose in cursed undeath as the Sodden Knight. Sir Francis detested shields and spurned them with utter contempt, earning renown for decimating enemy ranks with his two-handed fighting style while clad from head to toe in impenetrably heavy armor."
