So, I killed the last of the trio. It's the boss that conjures up two clones and teleports. I was able to defeat the boss. I delivered the last blow, which triggered a kill cam. But, just when he died, he teleported at the same time and now I have no body to loot off of. Also, the whole quest itself is bugged because the quest pointer literally points to the Daynas Valen guy's corpse. I have two of the amulets, I just need the third now.
