The flame-haired woman thought for a moment and then explained, "The reason the True Death Eyes went into an overload state is simple—it couldn't withstand the backlash from severing a connection with Hell, which is an enormous mass of mana."
"Let me make it easier for you to understand. Suppose your True Death Eyes can safely handle a mana load of 1. Severing your link with Hell instantly requires paying a price of negative nine million… and so on. The mana cost is astronomical. Given that your daily mana regeneration is limited, and the mana involved is of exceptionally high density, the recovery process will take an extremely long time."
"To speed it up, you'll need to find other sources—objects that contain equally vast amounts of mana—to fill that deficit caused by the overload."
"But, because the True Death Eyes is an ocular-based ability, the mana-filled object you find must be of a similar nature—it must be connected to eyes."
