In Skyrim, I really want to get a Daedric weapon, but I am only level 40. Could someone please help me get one without smithing or using the Atronach Forge?
There are several ways to attain Daedric weaponry, one is through the Daedric quests:
Another way is through smithing. You will need to be at least level 90 in the Smithing skill to make it yourself, but if you are level 45-50 (overall) you will start finding them as loot (very rare) and as you level up, it will become more common.
And last but not least, there are a few missions that involve summoned Dremora (the Daedra thugs), and if killed, have the chance to drop their weaponry. (They will not drop their armour).
