I was very much wrong about how Oblivion Walker works. There’s a total of 15 daedric quests, which all reward daedric artefacts for completion. However, a few of those give alternative ways of completion, which grant something else instead. This actually means the achievement is missable on a character basis. If you mess up on one character, the only thing left to do is to restart with a different character and try there. Technically, there is a way to exploit a bug in one of the quests, so you can make up for just one artefact, but other than that, you need to be very careful if you want to get this achievement.

Luckily, I didn’t get a chance to mess up yet and I did my research before continuing from last time, so I was ready. I have to say, I don’t like very much how this is working, though, because most of the quests involve you doing some very, very evil things in order to get the rewards. What’s worse, no one actually reacts to you doing any of it, and the game just moves on as usual. I would’ve preferred this to be handled differently, but I had to work with what I had.

In the end, I got all 15 artefacts and didn’t have to exploit the quest bug with Hircine’s quest to get both the Savior’s Hide and the Ring of Hircine. However, although I got all of them, I did not get the achievement. For a short time, I was afraid I wasted all this time for absolutely nothing, but luckily, I’ve found a steam thread which helped me get past the issue by using the console.

I have them all!

Skyrim – How to Fix Hircine’s Quest

It seems Hircine’s quest has a tendency to not complete properly, so a console command was needed to advance it up to a certain point. I had no issues with using it, since I had the artefact in question, so I did, and the achievement was mine.In case anyone else encounters this problem, the command to advance Hircine to the right position is.

setstage DA05 100 if you got Savior’s Hide
setstage DA05 105 if you got Ring of Hircine

If you have an issue with another quest, you can use sqs to check what stage your quest is on, and then setstage to set it to the correct stage. What follows is a list of all the daedric quest ids as well as the stages they need to be on along with you owning all the artefacts, in order to get the achievement.
