Helldusk Armour is a legendary heavy Armour that can be obtained from Raphael during Act 3.
Carixim, soul-stuffed forgemaster of hellish Avernus, hammers away ceaselessly at new creations. Questions of morality and destiny do not concern him. Conscience is for his betters. He works with cheer, his swollen skin moaning soothingly.
