Tonight, I got my Prismatic after killing Darathar. For those of you who don't know anything about the quest. You start it by gathering 26 runes all over the Shattered Lands. Next you have to Rez Lady Vox, kill some drakotas, and a few other nameds and then go kill Darathar. It's pretty gay, since you start out on the Isle of Refuge, and the end game fight is on the Isle of Refuge, just a different instance. Anyways, here's some pics of Darathar and my Prismatic. Yay me I'm finally done with this pain in the ass quest!
