The [Fantos Manuscript] was undoubtedly very powerful.
However, such power came with a huge downside. Its cost was just too high!
Signing a contract with a demon required Points, Skill Points, Golden Skill Points, or Golden Attribute Points. The same went for summoning the contracted demon. Although summoning the demon would only require 1/4 of the contract cost, it was still a heavy burden for any player.
Another important factor was that demons were easily restrained by holy water and similar items with holy attributes. Such items were not just damaging, but also lethal to demons.
If [Holy Water VIII] was like acid splashed onto a demon, what about higher-quality holy water? Perhaps one tube of high-quality holy water would be enough to vanquish any demon.
Based on Kieran's predictions, even if a higher-tier demon was facing off against the best quality holy water, they wouldn't last long. It was a matter of time before they would be turned into ashes.
