Ok, given this chart how would I decide on the skill values for an area of my sandbox campaign that I want to design as a 5th level challenge? You see creating a 5th level NPC allows me to do this... arbitrarily assigning a number really doesn't.
By giving them no skill, maximum skill that would be possible for a given level, something in between, or something off the charts. Whatever actually worked in the given situation. It doesn't require knowing stats, hits, attack values...... Just skills.
