Historically an aurabot wearing Victario's Influence had 2 options to deal with chaos damage. 1) Capped chaos resist with Prism Guardian 2)Blood magic with Coruscating Elixir. Option 1 removed the option to wear Dying Breath, sacrificing 18% aura effectiveness. Option 2 is extremely clunky to play.
Because of the power creep in recent patches it's now possible to get enough "Reduced mana reserved" to allow us to just reserve our mana instead of health. The life based aurabot is born.
