In a semi related question, if you were starting a new campaign and only had one player (solo), but were going to use a pre-exsisting module/adventure made for four 1st level players, without editing it, what level would you start that PC out at?
What level would one character be able to handle an adventure designed for four first level characters?
My first thought was make him 4th level, but that doesn't really take into account that multiple creatures will be attacking one person, instead of dividing attacks between four, so I was thinking of 6th level.
What would you say if there were two PCs instead of one?
