Previous data collected by Cheshireccat suggests that the book drops from black kats at a rate of 1 in 200.

Since I hate everything and want to see MMO players suffer, I think they should make them 1 in 250 instead.
Tell me.
How would this change make you feeeeel????
that would make me i have hope, players who suffer dont have hope!
so i can improve your suggestion:
to drop a Book Of Dark Rituals, you need to at least make a purchase of 14 prize boxes the previous 5 days before the event, then you will have a chance of 1 in 250 to drop the book, once you drop the book you need to make another purchase of 14 boxes in order to have another chance.
there now is hopeless and make player suffer more.
I'd be ecstatic if one in every 250 kats gave me a book. It beats the 0 in every 1000+ I'm at now.
