A more natural English structure would be: "Lamentably, you have failed in your mission and have cost Hixria tremendous resources. Your incompetence has earned you great shame."
Or (modified to be a little more casual/colloquial)
"Sadly, you have failed in your mission and cost Hixria a great deal of money, bringing great shame upon you."
Or (a combination that is a bit more formal):
"Your inadequate efforts have [or you could use "Your poor effort has"] squandered both your mission and much of Hirxia's resources, to your eternal shame..."
