Of course, energy supply was just one aspect of the Level System since you could not rise higher if you did not have a strong enough Sea of Consciousness and soul force, but that was not a problem as the Depravita of Gluttony had made sure to enhance them with Origin Force. Right now, the Level cap of Jormungandr was so high, that the only thing that stopped him from reaching Level 16 was time.
