On my current character I am trying to collect the 8 dragon priest masks and on the hunt for the final one. As I've been playing this character for a while I have explored a lot of the map so its hard to really plan where my search will continue. The easy solution is to hunt down word walls and eventually I should come across the final priest, so off I popped to High Hrothgar to get a word wall location. I get sent to Arcwind Point (I think thats what its called) but I have already been there and activated the word wall. When I got up to the word wall the word is glowing but nothing happens when I approach it and I can't complete the Miscellaneous quest to find the source of power. Is this just a bug or have I run out of word walls? I know there are some in places that are inaccessible unless you do certain quest lines and I guess the Greybeards would never send you there.

On another note, are named dragon priests with masks always present whatever your level? Or could I have cleared a dungeon at a low level and only come across a different levelled draugh?

The named Dragon Priests are always there. Only the generic ones, which are maskless anyway, are level-dependent.

The Letter from a Friend and Greybeards marking your map are nice mini-quests but unfortunately they are not free of bugs either. For example, quite often the Greybeards send you to visit Place A but the quest gets completed when you visit Place B instead.

In your case, if you are only interested in collecting masks, you can learn the locations here:

It's a bug, the game is not designed to send you to a wall that you've activated before. They wouldn't send you after a wall if you got all of them either, they'd just say that they don't feel any walls.

Also, Dragon Priests that have masks are fixed, you'll find them regardless of your level.

Cool thanks for your replies! I just had a look on the UESP. Potential spoiler below...

Oh yeah..........SPOILER ALERT BELOW..........

Arcwind is notoriously bugged also because its word is linked to the same words used in Marked for Death. When Ulda goes there I RP that she feels the aThu'um is tainted, poisoned some way, which as we know...... It is. She guesses its some kind of trap for Dragonborns and leaves well alone until she has the full Marked for Death shout.

There is another bug associated with Northwind Summit word wall. If you go there and get the word it will give a message that you have completed finding the word of power for master Arngeir, even though he didn't give you Northwind! So I only do Northwind Summit when Master Arngeir tells me to, that caps that glitch.

The Marked for Death shout also has an Audio glitch! The single word is Krii, the second is Lun. But if you get the first two word and use it, your char will say Lun, Lun. When you get the third word Aus. Then it works correctly again, shouting 'Krii,Lun,Aus' . My fav shout....it makes everything more kill able, even ice wraiths and Dwarven animunculi. Used on low level bandits they just sicken and die without a physical strike. And you can target several npc's at once.

You are welcome!

Yes, you have to join. But that's nothing, for another mask (which you say you already have) the whole of the Main Quest has to be completed.

Hmm, decision time! Not really a mage type character, but I do use restoration and shouts so maybe I should go for it.

This thread should be in the spoilers section.

yep, dawnguard, marked for death and drained vitality bugged. plus, the greybeard method of wall hunting can get bugged.

personally, it means i never goto HH to get the greybeards help and always predetermine if dawnguard will be deleted for any character and added later. or, i just make sure to have all 3 MforD shouts.

instead, i shout in a town and get the greybeards letters.

Yeah if that is the last mask you need, you'll need to join that organisation and complete its quest line to obtain it.
