wow How Exactly Do the Mythic+ Keys from Great Vault Work?

This one may be obvious to many, but in case you didn't already know, the Mythic+ keystone you get from the Great Vault does not function like everything else in it. It might be easy to miss this detail if you're constantly pushing higher and higher every week, or are just extremely consistent and do the same level keys every week or, like me, just didn't really pay that much attention to the whole thing.

There's been some discussion over how exactly the key from the Vault works, as it might not be consistent or even bugged, but the general consensus being that while all the gear from the Vault is determined by your performance in the previous week, your Mythic+ key is not. Currently the majority of players think/have experienced that it is actually determined by the highest M+ dungeon you've completed in Shadowlands Season 1 overall/ever. If this theory is correct, you will always get the maximum level you've completed (not even timed, just completed) minus one, so if you ever do a +15, you'll always get a +14 in this season.

There are some examples of this not being the case, however, with players reporting they did not get a 1 level lower than their seasonal best, but then there's also players reporting they got a higher key than their overall best or their previous week's best as well. So it's a little hard to determine what part is the bug and what the intended way of functioning, but for now the majority of players are experiencing it working in the all time seasonal best key -1 each week from the Vault. If you had a different/not consistent with the theory key drop for you, let us know in the comments.

While the uncertainty of what's actually going on here might not he quite as helpful, hopefully it still  helps some players. So thanks to im_anDe for bringing it up! You can check out the reddit thread for the examples of players getting various results.

Don't have any ss of it, but some weeks ago, i did a +5 key on 2 alts, and a bunch of lower keys. I got +6 keys in the vault the following week on both alts. The same happened with the people i played with.

Actually, this may have happened to me.

I have done a 15 key and I believe last week I did a 13. But the reward I got was 226 this week. I just thought I may have done a 14... I will need to verify this however. Raider IO has not updated our run yet.
