An upgraded, elite version of Mr Du'lora.
To clarify something ahead of time, raging mind "encourages" ranged characters to hang back (5+ squares away) and target defenses that are not Will. The downside? Will is one of its lower defenses (the other being Reflex). To me, this creates a tactical dilemma: do you target Will to get a better chance at landing a hit, risking the chance for it to have an easier time slamming you with incite fury (or grab you and trigger burning rage), or play it safe and go after Fort or Reflex?
