Technically, 4 levels 2's is equal to 5 level 1's.I'm running Kobold Hall to introduce 3 players to 4E. We're using the KotS pregens Cleric, Rogue, and Fighter. I'm considering upping their levels to 2 or 3 and go that route rather than simply dropping the number/type of kobolds.
Suggestions? (KH spoilers should be expected)
When I ran the PCs through, I did modify the adventure somewhat, but the terrain became functionally equivalent. The PCs had a heckuva time in the first two rooms. It was really hard for them.I don't think kobold hall is tough enough that you have to up the PC's levels yet. The first two rooms should be fine to ease 3 pcs through. The third room can be slightly more more dangerous, but as long as your pcs still have their dailies it works out.
