For reference: There is a duell in the module where a shaman tries to secretly help one NPC by continously casting Cure Wounds on him while supposedly only helping him "stand up" after he intentionally let‘s himself fall prone. To spot this, a PC has to specifically declare checking for interventions a then suceed a DC 15 perception-check despite being within earshot…
It is the first long module I've run. Still going after 3 years (we're slow). My players say they're enjoying it but I've spent so long trying to fix things I might as well be home brewing.
I think anyone that wants to use a module to simplify GMing (like me) should choose anything else. Anyone that's ok with home brewing doesn't need the module. Maybe read the plot overview at the beginning and fill in the blanks.
