Sure, I could just spawn them via the console, but it would be even funnier if it were legit.
"Say, J'zargo, do you have any of those exploding scrolls left... ?"
I'd do this myself, one of many things I want to do, but the CK isn't out yet. I'm used to using the GECK and the past sets, but the current method of modding is a bit brain-bending to me, and I don't have the time to get into learning entirely new things which would likely result in stress headaches. So, if anyone wants to beat me to the punch before the CK comes out, then feel free.
Though I realise that this may be a bit of a nightmare before the CK comes along, having to add a vendor chest for J'zargo and everything.
