I'd like to get the achievement for obtaining all of the Daedric artifacts.

I can't decide what sort of character to create. IDK what would be best.

So, I've come here for your help. What build do you think would be best for accomplishing my objective?

I should add that I already have a pure warrior, mage and thief. I also have a spellsword.

I'd like to try something new.

I once played a character that did this. Alana the Acquisitor. She was a young but promising member of a neutral but ruthless shadow organization out of Cyrodiil, who was sent to Skyrim to investigate and acquire not only the Daedric artifacts but also other items of note. She got lazy about some of the shielding techniques she had been taught, and possession of some of the darker artifacts started to corrupt her to the point that, when she went to investigate a certain dagger, she ended up joining the Dark Brotherhood.

Edit (because I posted too soon) - her primary skills were Stealth skills but with Enchanting instead of Alchemy, since the group was dedicated to the study of these objects.

Let me tell you this first before another "Oblivion Walker" thread pops up.

When doing Hircine's quest, get the ring first, then the hide. You'll thank me later.
