Chapter 386: Date and Discussion P4

"How does using foreign mana affect you?"

Eren asked as he swung Nina round on the tune. The latter gracefully returned to her previous position after completing the spin. She replied as she followed Eren's lead again.

"First of all, pulling something like that can't be done by normal methods. As a second consequence, using foreign mana without any pre-arrangement would cause your mana core to burst. Rankers would die if they used foreign mana without knowing what they were doing.

The third hurdle in using foreign mana is one of the biggest reasons why nobody shouldn't try heretic methods like those. Foreign mana is imprinted with the will of its respective world, and so it should place a heavy burden on the user's consciousness. The effects of the foreign mana would progressively affect the rankers as they used more and more of it.

I don't know much about this field either. Just consider that it would be problematic for the ranker when the burden exceeds a certain limit."
