If you get 45 calcified fragments, you get to finish the quest called "hunger pangs", this allows you to get touch of malice. There are afew little missions like, kill this taken knight on the undying mind strike, and then another, delve into rasputins bunker and defeat a taken centurion, and the last mission is a pain in the ass, but after you do all that..... you get touch of malice The 3 pains -50+ hadium flakes (if you wanna upgrade it, it costs hadium flakes) -45 calcified fragments (use one of those sites to help you out with all the locations) -the Last mission (I can help with that if you so desire) Why you want the gun: it never runs out. When you are on your last shot, it takes from your health. It's really helpful on oryx and the sisters.
