The Voidfangs are like all Aharmkara gear. For example, Young Spine says "give your arm, oh bearer mine. Let me help you fill the world with teeth" and the Claws of Aharmkara says "look at all this life, oh bearer mine. There is so much left to burn". And, as of right now, I don't possess the Skull of Dire Aharmkara. Can someone remind me? I know the exotic perk is called "delusions of grandeur"
