Everyone seems to think that the only fragments are the ones you find laying around. The hardest part for me was the court of oryx tier 2 and 3. I must have used 20 stolen runes and I am still missing one fragment. And actually getting decent people to run tier 3 with is hard. The crota fight took way longer than it should have because randoms are terrible and for some reason don't like to down him and for some reason like killing adds while I have the sword in my hands. And for your information I do have the touch of malice so I'm not "butt hurt" that I don't have it
