Yep, the title says it all. For our 10man groups first OS3 kill, our Sartharion MT was a Voidwalker. Fully buffed he got up to 78k HP, and ate breaths like a champ. We weren't the first group to do this, but i havent seen any other videos of it out there so i decided to post the one i took. Some of you might think this should be nerfed, but you have NO idea how hard this was for our warlock to pull off!
