This skill can only be used in PvE, and is unusable by heroes.
There is a duplicate of this skill for both Kurzick and LuxonAllegiance rank. They differ only in appearance, and in which Allegiance rank they use for their progression. You may equip only one of these duplicate skills at a time.
As with the Dragon Slash scenario, using this skill with a reasonable Allegiance Title in combination with "For Great Justice!" will result in a substantial adrenaline gain, and will recharge almost all adrenaline skills. Also, since the skill is not an elite, consider alternating with Focused Anger along with the shout.
