I've been thinking it would probably be left best to leave it superfluous. Give players a level, and set bosses at a higher one, mooks lower, and challenges at around our level. How much they hurt it will really depend on the creature some beasts may have high mage resistances, or some may have tougher scales. Leveling up can be done off screen mainly.

But before we make an OOC I will probably need to insist on either co-gm, or that everyone helps make some missions during the adventures. I don't really have a good track record when it comes to back to back missions I usually do best in the 'epic' encounters.
