I'll be willing to let Assassinate 30 go for 1b! The book is nearly extinct and I'm pricing it cheaper than some other readily available books already! As for Ifrit 30, I'll take offers that you believe to be fair. If nobody is interested or if the offers aren't anything that I care about then I'll just donate my book to @Martin
Finished selling all of my Assassinate 30 books . Not impressed by any Ifrit offers so I'll be closing this thread!
They aren't obtainable through mobs, only through GPQ which has been disabled for about 1.4 years now, but will be released after update 55.
