Hello we have started the adventure Princes of the Apocalypse and we are now at the stage of my PCs exploring the 4 main bases of the Elemental Cultists. They have started at the Earth Cultists in the Monastery. Our group is small only 3 PCs with one henchmen so four in total. The Henchman is strictly the healer guy. I am wondering about levels everyone should be at or around for the other Cultists above ground lairs. I have them at 5th level since there are only 3 and it's been okay but just curious what other DMs might have their PCs at.
