"You can say that… there are many kinds of swords in this world, and some are special. This white sword is perhaps the most special of them all. But, I can't use it. And as long as I have this, the only special sword that I can use are the ones like that crimson sword that you have seen already."

"The downsides are many.
When I got it, I lost all my levels and most of my unique stats were sealed along with my servants, skills, and powers.

Some common things will become available with level up as well. That's why I am so focused on leveling and hunting."
