The Black Axe of Krell is a huge double-handed axe carved from a solid piece of black obsidian rock and enchanted with powerful spells. When the Black Axe of Krell bites into flesh, it leaves behind jagged shards of black metal that swiftly eat their way into the victim's heart. It is used by Krell most commonly, but has also been used by other Wight Kings and Vampires that are not Lahmians or Necrarchs.[1a][2a][3a][4a]
