If you guys want to test certain scale combos, you can make a map where scale modding sites are assigned to all the provinces (Well of Pestilence for death, Strange Opening for misfortune, Temple of the Raging God for turmoil, Totem Poles for luck etc). Or you can just mod a new site that increases all the scales you want to test things with.

The good part about that is that modifying scales for testing with sites is going to cause no fluctuations due to dominion, since the effect is local to the province and always tilted toward that scale at 3. If you want to test a scale of less than one, then you need to use dominion for that.
