The Spectral Dragon Priest is an ally that can rarely spawn--a three percent chance--in combat for sixty seconds, much like an Atronach, when the Konahrik mask is equipped.
Physical appearance[]
When using the mask, the Dragonborn must be struck while at or below fifteen percent health in order for it to appear. Upon death, it leaves a temporary dust cloud in its wake, and can occasionally leave an ash pile as well.
The Spectral Dragon Priest can also be encountered as an enemy in Yngol Barrow if facing Yngol's Shade at higher levels.
Combat[]
The spectre makes use of Shock and Frost spells offensively. It will reanimate corpses during combat, or, if no corpses are available, may summon a Storm Atronach.
Summoning with commands[]
Alternatively, the dragon priest can be summoned by the unused Conjure Dragon Priest spell if Console Commands are available, and when summoned, it will act the same way as if it were created by the mask.
