Having a session zero for a campaign my group is starting this weekend. It’s set in Eberron most likely using the current rule set but maybe sticking with straight 5e(that will be one of the things we determine at session zero).

Since Eberron has so many interesting Warlock Patron ideas and ways they could lead to epic adventures my four players have talked about possibly doing all warlock party. Each with a different type of patron. We don’t multiclass so they would be straight warlocks all the way. I have never DM’ed for a mono class party before and I was wondering if any of y’all have, especially if it’s been all warlocks , what were your experiences? Any advice you would give? Things that I should consider when making encounters or devising the campaign that I might not think about but I should factor in?

I am about to start planing out a homebrewed campaign and want to create some new cults to use to fill out this world and looking for some inspiration. So what’s your favorite cult you created for your world? What made it feel unique or especially creepy/menacing? What made them memorable to your players?
