I'm also thinking of running Jzadirune sometime soon, and had a couple of questions:
1. The "Player's Map of Jzadirune" seems to available to them twice - once as a sketch on a piece of leather in G5 (Keygan's Bedroom), and then again in on the wall in room J16 ("Map Room"). This seems a little odd. Is the intent to make the map available again in case they didn't get it from Keygan, or am I not reading this correctly?
2. The Vanishing seems poorly explained. I understand that there's a one-day incubation period, but after the initial Fort save (and possible 1d6 Cha loss), what happens? An additional Fort save at DC 15 every day, with another 1d6 Cha lost until the victim has disappeared? It's unclear to me.
Thanks in advance!
