I use the Creation kit, I am on PC not console, I am a Modder and that is not how difficulty works, higher difficulty means you do less damage, enemies do more, adept difficulty is 50/50 you can change difficulty ingame at any time it does not automatically increase an enemies level if you set it to legendary and it does not go down if you set it to novice, enemy scaling counts towards your characters level nothing else and correction alduins scaling is 1.20 your level not 1.25 as I said before
You are acting as if I've never played skyrim on a pc either or don't have friends that do? I have no reason to make this stuff up, I don't care if you believe Alduin is the weakest. My problem here is that everyone calls him weak yet they forget the fact they never actually fought him one on one. Added with all the people haxing their gear and using console commands to cheat through everything there's hardly a reliable reason to justify that Alduin is the weakest.
Tho it should be noted, on YouTube there are video battles of Alduin vs harkon and Alduin vs miraak. Alduin always owns them both. Decipher this as you see fit before saying which is the weakest. Imo harkon was pathetic. Miraak was decent.
That's because Miraak and Harkon weren't allowed to regenerate health, Harkon probably wasn't in Vampire lord form and didn't have his gargoyles, and Miraak didn't have his dragons.
And UESP I would actually use over the CK, because it has pages for quest walkthroughs, best quests for low/high levels, and a ton of stuff you would never expect. It takes stats from the CK.
