I think my favorite item that you get from the Gods in Skyrim would be Mehrunes Razor. That weapon is just too good. What is your favorite item?
Mine was probably the Wabbajack. And my favorite quest was when you go to the party and cast the spell to take off everyones clothes. Hahah I couldn't stop laughing
The Black Star (Azura's Star), since it allows me to keep enchanting stuff without getting lots and lots of Soul Gems.
Dawnbreaker. I found it first, and I used it almost till the end of the game, seeing as there are tons of undead enemies.
Wabbajack was the most fun for me. I also really enjoyed that quest, though really all the Daedric quests are pretty fantastic (and well-written)!
Mine would have to be the Guevenne Staff being able to summon a daedra at the early stages of the game is quite useful, but from what I can remember the quest is quite challenging if your not prepared.
Mine was the Ebony sword you retrieve from the room inside Dragonsreach. I thought it was so awesome that you could power up the sword by killing people who trusted you. That tickled my evil bone thoroughly .
Dawnbreaker here - I didn't get all of them, but there are so many undead that it just turns into your main weapon. Mehrunes Razor is my second favorite, took enemies down so easily with it - statistically its 1 auto kill every 50 hits (2%).
The Wabbajack has to be my favourite too. It's random effects are hilarious and have different effects on different targets. IDK how useful it can be, but it's fun playing with it.
Daedric axes all the way! They look monstrous and amazing! Most intimidating weapon or piece in the game in my opinion.
I always have my Daedric Sword equipped. It's a great one-handed sword and it's a great addition to a nice Destruction spell. I can take on any enemy with that combination (and my powerful shout of course).
I love daedric swords. In fact, I wield dual dardric swords the most than any other weapon in the game. I usually enchant one sword with a regenerate stamina spell and the other with a regenerate health spell, so can fight opponents without loosing much health or stamina.
Mehrunes Razor is also my favorite. I love the design of the blade and it can cause instakill. Also the blade is easy to craft and improve compared to other items.
My favorite is Dawnbreaker and I also like Wabbajack it's funny because you don't know what magic or something will pop out.
The Wabbajack is easily the coolest Daedric weapon and the quest for it was very entertaining and unique. The best thing about it is every time you use it you have no idea what it is going to do so even blasting a chicken is interesting with the Wabbajack. The best, as in most effective Daedric artefact is probably the Azura's star. An infinite Black Soul gem holder.
