Let's be a little fair now though. There's no way in hell you will beat even a bear in vanilla Skyrim at level 1 at the hardest difficulties. Not even decked out with a shitton of potions. You need perks, which you won't have at 1. Or even by the time you're level 10. And unless I create some super enchanted armor and weapons, even draugr deathlords will pulverize me. After I saw just how ridiculous enchant could be, without even using the alchemy loop, I've stuck to vanilla loot and elemental fury for weapons instead of enchants. More fun anyway. Plus I don't spam up smithing either.
Earlier I did the Black Star quest with a character, and I had a necklace something that gave 30% fire dam reduction, agent of mara, and maybe some generic saves vs magic ring - and still had to chug some potions fighting dremora. I could have spammed up alteration, sure, and been pretty much invulnerable with all that, and maybe a potion, but ech.
The perks in vanilla Skyrim are pretty damn boring though, and that Requiem stuff sounds a lot more interesting.
