The Shadow Gate Seal works in a way that they user does not have to open it all at once. At 10 percent the user is strong enough to take on even the strongest humans. At 20 percents, the user can defeat small armies by themself. At 30 percent, the user would be able to demolish weak to medium strength'd demons. At 40 percent the user can make entire continents bleak and desolate.Nothing over 50 percent has ever been observed even when the user is still on seal one. This makes it difficult to gauge the actual power the user can gain from this seal.
