A blur of rolls ! Love it . Back on the wagon for us , no biggie . <| sep |> Short answer You won ' t need any extra elemental damage . Long answer Since you ' re scaling physical damage you could indeed run hatred and herald of ash . However , elemental damage without elemental penetration is worth much less then physical damage and chaos damage . It could also cause you trouble when running elemental reflect maps . But let ' s have a look at what you sacrifice for it . CI not only brings a 15 % more energy shield multiplier , but also immunity to chaos damage . When playing low life you ' d need to stack a good chunk of chaos resistances . Also , you are not bound to Shavronne ' s Wrappings , which again is a huge boost to your ES pool . I dare say that going CI makes your character overall 50 % more tanky . Now let ' s talk about curses . Since you ' re dealing physical damage and damage over time Vulnerabilty comes to mind . However , Vulnerabilty can be activated with Witchfire Brew . So you have mana for another curse . Now you could even grap Charisma and the 4 % reduced mana reservation and you could run a 3 rd curse without going low life .
