Well Phogoth is the only strike boss that is an ogre, and the helmet does resemble that of a light eater ogre. Unless for some reason it drops with Omnigul? Vex have Imago Loop, and warlock gauntlets, Undying has the titan mark. Cabal have Tread upon stars, Mau'uls Maulers, and Flayers have 3 cloaks. Hive have Grasp of Malok, Omnigul with the bond, and Dark Blade helm, Darkblade's Spite. Fallen have Does not Bow, and Baron's ambition, Mr. Nohouse's cloak. Am I forgetting anything else?
