Seeing as I had around 10 on my main and I have not been out looting, that's what I was able to pick up at the vendor, they aren't a good sale item so I'm sure they're being stockpiled (low weight) to form pages and pages of insta-win.
ICly, my character will view the use of this item as reckless, pagan, and something that needs to be dealt with immediately. (Considering one use of the thing could kill every NPC layperson at mass.)
