The special affix greatly reduces cooldown of the Mass Confusion. With Tribal Rites and Unstable Realm rune, one can reduce the cooldown to 8 seconds (before the cooldown reduction stat), which allows keeping monsters Confused almost permanently.
Prior to patch 2.0., it had a slain enemies rest in pieces attribute.

- The description, along with the property to permanently kill enemies, is a possible reference to the Planescape: Torment RPG unique weapon, Blade of the Immortal, forged with the sole purpose of being able to kill an immortal being.
- It is one of the Legendary weapons without a unique model, using a recolored Ox Bone Blade appearance instead.
