I did some testing in the Emerald Graves, and health seems to vary for different types of enemies. I've included my figures in this document, but the short of it is that "easy" mobs have a ~80% increase, "medium" mobs have a 40-50% increases, and the one elite I tested, the giant, had a 20% health increase.
While it's not in the table, armor seems to stay consistent, in line with your dragon test.
Wow, that's great!
But I'm a bit surprised by those numbers. Did you have any Trials enabled? You mentioned an elite giant, which suggests Trials. Ideally, we need numbers with
no Trials enabled, since we know that Trials completely break the normal curve for everything having to do with enemies. If Walk Softly is enabled, some of the enemy values are randomized, so one wolf might have a different value than the next wolf.
If Trials were enabled, any chance you could redo with all Trials disabled? If not, maybe at least label the tab in the spreadsheet with what Trials were enabled?
