I am currently DMing a campaign with a group of level fours. One of the four characters is much less experienced than the others.
I have planned part of my campaign for people who are lv.10+, and would be very disappointing if they never reached that point, as I have put a lot of time into it.
However, we are all extremely busy, and can only find time to run a session around once per month for 5-6 hours (but the rate will probably increase in the summer). Next year some members will be going to university, and there is not much guarantee that they will stay local. Even if they do, the business factor will only increase. In any case, I would like to get to the awesome part of my campaign. This requires them leveling up a lot. One issue with this is that the less experienced player may get overwhelmed with their abilities. They are playing a Paladin.
I have started them at lv.2, and they are lv.4 after three sessions so far. Should I continue leveling up at this rate? Or should I level them up at a much slower, regular rate, with the possibility that I will not play my epic part of my campaign?
