I'm trying to find a daedric sword somewhere in the field or through a quest. I don't really care the state of it - enchanted or unenchanted. I didn't pursue the smithing tree because I'm aware of the exploit and want to avoid it completely. Is there somewhere in the overworld or a dungeon that I can find one? I'm level 36 by the way.
Why do so many people call it an exploit? It's not yet balanced, and hopefully Beth fixes it, but they intended you to be able to combine all 3 crafting trees in order to make stronger gear - if they hadn't, they wouldn't have made fortify alch/smithing enchantments or fortify smithing/ench potions. 'Exploit' insinuates taking advantage of something that wasn't intentional, but the three skills working together was intentional.
The three skills together isn't an exploit - the real exploit is the resto potion trick, which is taking advantage of a bug in the game.
Well if it's leveled, yeah then the only way to get one is to make it yourself either through crafting or through the atronach forge.
Maybe you could get one from Mehrune's shrine (I think the quest opens it up at level 20?) you could keep coming back and farming the dremora/daedra there and hope one drops one but I've never seen the daedra use anything other than 2h weapons.
