After acquiring Konahrik's Dragon Priest mask does it add a spell to the conjuration list so you can cast it like an Atronach ?

The full description of the enchantment Konahrik's Privilege is "When low on health, has a chance to heal wearer and damage nearby enemies, or summon a powerful Dragon Priest defender".

On the Wiki it has a spell listed on the conjuration page : (Conjure Dragon Priest for 60 secs)Summons a Dragon Priest for 60 seconds.Available from the Dragon Priest Mask http://www.uesp.net/wiki/Skyrim:Konahrik. http://www.uesp.net/wiki/Skyrim:Conjuration

Not unless it only appears when you wear it but i have the mask and it is not in my list-why dont you try it and see then we can all be the wiser
