How to obtain Bloody Moon Spellstone?

[Natsuma]

Hello there,

As most hunters out there, I really want to get my hands on that new sword: Kouyoh Hime / 紅葉姫

We can get it against 5 Bloody Moon Spellstones, and here goes my question: how do we acquire them?

I guess it has something to do with Extreme Quests but as I've been rather inactive lately, I didn't have the chance to try these quests yet and I thus know nothing about them either.

Thanks in advance for your answers!

you need 13500 of the basic stones for a single item (or 150 of the better ones), with really, really good luck you'd need to spend at least half year doing EQs to get a chance on this, that is the best case scenario
just forget that this exists

I see, thanks for the quick answer!
I'll try to get my hands on Daisy Chain instead then haha

It's just as hard, considering...
