So me and my friend, got everything well on crota, it was just one more hit and he was done and we wouldve gotten the trophy. But then...when I was about to shoot my ghallarhorn, a -blam!-ing thrall, yes a thrall decided to pass by where I was so that the rocket would kill me instead. The thing is, i was invisible so that they wouldnt get close to me, but it seems, that thrall haf supervision with x-rays and shit and saw me, on the exact moment that I was about to press the button to shoot that damn crota...People, beware the thralls. As their name can also come from Troll.
