Just ran my group through the first phase. Love it! The inclusion of maps helps me run it on Roll20, unlike several other products.
A couple of minor things/preferences:
It would have been even sweeter if there were a scaled map for the canyon encounters. Those sound quite amazing!
Regading the estate area: The lack of a saving throw to avoid falling into the pit seemed a bit unfair (at least when a new DM like myself tries to narrate that for a group of veteran players). I understand I can "do what I want" but I want to confirm if the lack of a saving throw is an error. And if not, I'd just like to hear Tony's rational so I can try to make sense of it when I narrate it. Is it supposed to be a "floor underneath you collapses?" Perhaps an acrobatics check to grab onto the ledge and remain hanging? I don't know. I also wasn't sure what sort of distance to allow perception checks (when NOT in combat, of course) to notice them.
Overall, great stuff! The more you release products like these with maps, the more you will have me as a loyal customer.
