I just started a 4e campaign that I'm trying to plan out around classic elements. However, I'd like to incorporate the GDQ module series (at least initially, the Dungeon magazine conversions by Chris Perkins) and I'm having a problem making the levels work in a 1-30 campaign. So here's my question: What's the downside to straight up re-leveling adventures? To be more specific: I'm thinking of kicking off the paragon tier with the adapted Steading of the Hill Giant Chief, moving straight into the frost giant sequel, and then going to the Eclavdra/door to the Underdark encounter from his fire giant adaptation. Obviously, this entails re-leveling hill giants, frost giants, and other key NPCs. Anyone see any negatives to just doing that? Are there weird powers or effects I need to watch out for in those adventures? Love any thoughts you might have; thank you!
