"Legend holds that the highest ranking Dragon Priests were granted magical masks - strange artifacts that defy the laws of time, and grant their wearers powerful enchantments."
A Dragon Priest Mask is obtained after defeating each of the eight unique Dragon Priests that appear in fixed locations throughout Skyrim. Each mask is unique in color and varies in material. Masks are named after their respective masters and have unique effects; they are defined as either Light or Heavy Armor.
All Dragon Priest Masks Require the Arcane Blacksmith perk to upgrade them.
Most dragon masks can be found by talking to Arngeir in High Hrothgar, and asking if he has located any words of power. Several words of power are guarded by Dragon Priests.
This dragon mask can be acquired from the Dragon Priest Rahgot, who can be found in the Nordic Ruin of Forelhost, south-east of Riften a top the near mountain.
This mask can be acquired from within the central barrow in Labrynthian. It is unlike the previous masks; rather its purpose is to gain access to the Dragon Priest Shrine when worn within the barrow it was found.
Enchantment:The wooden mask hums with an unfamiliar energy.
This dragon mask can be acquired after collecting all the previous masks. To collect this mask entry into Bromjunaar Sanctuary is required.
The sanctuary can be found within the central barrow in Labrynthian. Here lies a Wooden Mask that sends its wearer back to a time before the destruction of Bromjunaar Sanctuary. The central focus of the sanctuary is the Dragon Priest Shrine.
Once the eight masks are placed in each respective slot on the shrine, the final mask Konahrik is revealed. The other masks may be taken from the shrine once Konahrik is obtained.
Enchantment:When health is low, has a chance to heal wearer and damage nearby enemies. For a full list of effects, see Konahrik.
In addition to Dragon Priest masks having powerful enchantments, it should also be noted that certain masks have the highest armor rating of any headgear available.
For Light Armor, Krosis and Volsung have the highest base armor.
For Heavy Armor, Konahrik has the highest base armor.
Upon retrieving a mask placed on the shrine, all smithing enhancements will be removed from the mask. This is likely because a new copy of the mask is added to the player's inventory upon retrieval.
Sometimes, If worn with hooded equipment it will cause your characters body to disappear, clothes are still shown, but as an empty shell. While the hood of the gear stays present. Tested with Arch-Mage's robes (Also happens with the Falmer Helmet). (This can be temporarily fixed on the PC by pressing F5 (quicksave) and then F9 (quick load), PS3 users can save and load to fix the problem, also temporarily.) Alternatively, there is another option to remove the Hooded gear, and place the mask on your head, then re-equipping the hooded gear.
If given to a mannequin the mask will stay there forever, even if it is withdrawn will be doubled if you leave home and return the mask will be there again. (The solution on PC is open the console, click on the mannequin and type "resurrect". WARNING: this command will delete all items on the mannequin).
If a follower is holding mask and is made to join the Blades, the mask can sometimes disappear from their inventory.
