I am starting a new adventure with 3-4 members and was wondering if their was a formula for me to use to determine how many creatures and what level of creatures I should be throwing at them to provide a challenge, but not make it too easy or a slaughter of my players?
I am still trying to wrap my mind around the idea of Skirmishers, Elites and so on.
So for example, if I have an 8th level Elite does that mean a team of 8th level players is a decent challenge?
Should I be throwing (4) 6th level players at that 8th level elite for a challege?
When I played Mutants and Masterminds the forums came up with a formula that worked great to determine what to throw at your players scaling to their number of players.
Has D&D fans come up with a like process?
