Lost Miwok Artifacts Event

What? All I've been hearing in not only this thread but in-game is that the ring only requires ONE SCROLL to be bought. I thought only the chair required spending a ridiculous amount of NX.

Can anyone else follow up on what MetaSeraphim is saying or give a more definite/elaborated answer?

I'm pretty sure it works the way he/she explained.
total waste of money event.
