The recommended scenario level is equal to the average level of the characters in the party, divided by 2 and rounded up.
This would be considered “Normal” difficulty. If players desire an “Easy” experience, they can reduce the recommended scenario level by 1. If a more difficult experience is desired, the scenario level can be raised by 1 for “Hard” or 2 for “Very Hard.”
A scenario’s level can be set to any number from 0 to 7, but cannot be changed once the scenario begins. Monster base statistics, trap damage, the amount of gold received from money tokens, and the amount of bonus experience for completing a scenario are all dependent on the level of the scenario being played.
