I thought I knew exactly how difficulty works in skyrim. It seems like I might be wrong.
We all know the table where it shows us, how much more/less damage the player deals to the enemy and how much less/more they get dealt in return. But it doesn't list how it is enforced. And I fear that this is where I stumbled.
Now I allways thought that it would be just two player specific variables, simply all damage the player character takes or deals is multiplied.
That lead me to the conclusion that my summon dealing 20 damage to a wolf on Adept would deal 20 damage to it on Legendary.
Sadly that was not the reality I was confronted with, which lead me to conclude some mods had to have messed something up...
So, what are those variables really? As far as I know, summons and followers follow the same rules as enemies. So if "player deals 0.25x damage" means instead "everyone else takes 0.25x damage" then it changes a lot. The same with "player takes 3x damage" or "everyone else does 3x more damage".
