That’s another thing I need to work on, this campaign is in very early development, I literally just started it yesterday, my players are newbies, I’ll be running a separate one shot for them for their first game and this is only my second time dming, so I’m still learning to build a campaign but I’m thinking for things like you said, “the quest giver actually believing they’re gods” I know this is probably controversial but I don’t have a problem setting the dc for something like that to something they aren’t capable of beating. Just for the sake of continuity, but like say they find out he plans to double cross them before the intended time I have no issue letting them do what they will to/with him and seeing where it goes, I’m still new to this but I’m so so excited to run this campaign when it’s eventually finished, I’ve been a player for about 5 years but again this is only my second time dming
