I'm about to start DMing for a group of 7, mostly new to Pathfinder. I myself have not DMed Pathfinder before, and haven't played it recently. We'll be going through the Mummy's Mask adventure path, which (reportedly) has a considerable number of traps.
For normal fights I can always just double the number of enemies, and for bosses I can just throw in some extra mooks and give the boss slightly better stats. But I'm not sure how to scale traps up for a larger party in a balanced way. Should I increase the skill DCs? By how much? Should I increase the damage the traps deal? By how much?
Note that this is an existing, published adventure path, not something I'm designing explicitly for this party. I'd prefer easy solutions, like adjusting numbers, over harder ones like adjusting placement, mechanics, etc.
