So after spending nigh on 4k on pots,flasks food and repairs I finally got my darned cloak at 520 ilevel was tough ..almost made me rage quit but hell it felt good when I got it..I think neighbors 2 streets away heard me yelling ;-p
what did I do?..I brought a shammy and a druid to sit just outside the phased area to buff me with earth shield and motw before each attempt..I macro'd all my def and off into 2 buttons to prevent panic when he would spawn all his attacks at once pre potted virmens bite..not the usual but I did use bos and st on the adds I think its mainly down to rng as I had over way too many attempts where the second he was attacked he would chain through all his attacks and blobs at once the attempt where I managed to down him he didn't spawn the bloods till he was under 40% hp and with all defenses popped and earth shield I wasnt instagibbed like previous attempts where they spawned at the very start of the fight
so..share your experiences getting the cloak as a rogue and any hints and tips for others trying like a mofo to get this done ;-p..wish I had frapsed it now tbh but there are a few diff approach guides on youtube
