"Heh. That's right, mortal. By channeling my divine rage into power, I have forged a new instrument with which to destroy you. You must realize the consequences of my learning rage is a source of power. My fury runs deeper than any mortal mind can ever comprehend which means my might will be unrivaled too. And this scythe will carve a reminder into your mortal flesh with the strength of my divine wrath!"
