Just curious to know. i have 5 atm and am about to try to get this trophy and wondering if anything can mess it up thanks.

Yes. More than one of the quests give you a choice at the end, one of which will give you the artifact and the other won't. Clavicus Vile and Vaermina spring to mind immediately; there are probably others as well.

This.

however, if you have botched one up, it is possible to get both the ring and the hide from "ill met by moonlight" (Spoilers here btw, if you don't want them) which both count towards the acheivement. You simply have to save before you go into bloated man's grotto, then help sinding kill all of the hunters. Hiricine should then give you the ring when you leave and commend you for turning the hunt around. Then go back in and kill sinding, and skin him. Hiricine will then also give you the hide.

THis...homever Hircine ring doesn't count towards the achiviment.if you want the achiviment you must at least...Kill silius at Mehrunes, quest give Barbas to Clavicus Vile and get's Vaermina Staff(f0ck the staff,it svcks in my opnion it's better save the priest,since he a very powerfull companion.And also there's 16 artifacts...you can just throw Vaermina staff away.)

Really? I don't think I picked up spell breaker or the tablet thing that gave you extra skill points but I still got the oblivion walker achievement. Doesn't the tablet count?

I respectfully disagree. I got the Ring of Hircine instead of the Savior's Hide, and I still unlocked the Achievement. Both the Ring and the Hide count as Daedric Artifacts.

Plus, it even says so in the Strategy Guide. That's why I went for the Ring. Not only does it still count towards the Achievement, but I was going to do the Companions Quests right afterwards and the Ring of Hircine really comes in handy when you are a Werewolf...

I abused the bug to get booth items.And i can afirm that i dind't get the achiviment.Because after getting 15 artifacts i still needed to get 1.So i picked up the Mace of Malacath and throwed Vaermina staff into the obvilion Lava rivers.And i finnaly got the achiviment.And i must say...ridiculous achiviment

I think I know where you went wrong. There is a bug/programming curiosity that doesn't allow the Skeleton Key to count as one of the necessary Artifacts.

I had 14 (including the Ring of Hircine, Spellbreaker, etc.), and joined the Thieves Guild so that I could complete the achievement. I got the Skeleton KEy, and nothing happened. I kept it for a week of game time (cleared out 4 dungeons just to give the game a chance to recognize that I had the damn thing) before getting fed up and giving it back to Nocturnal. I then went and got Mehrunes' Razor, and magically the game gave me the Achievement as soon as I claimed the Razor.

So going by the Strat Guide and my own personal experience, I can confidently claim that both the Ring and the Hide count towards the Oblivion Walker Achievement. It's the Skeleton Key and the whole "possession" issue that messes it up with the Skeleton Key.

I missed one articfact but got both Savior's Hide and Hircine's ring so that saved me

In my stats it says I completed 14 Daedric quests.
