After collecting the 8 Dragon Priest masks. Proceed to the barrow in Labrynthian to find the Wooden Mask that sends you back in time to the Dragon Priest Shrine. Place the 8 masks in each respective slot to unlock the reward Konahrik.

Konahrik is the 9th Dragon Priest mask which has some rather interesting traits. When the wearer is low on health, there is a chance the mask will knock back enemies, heal the wearer and any nearby allies, and grant a fire cloak for a brief time. Also, on very rare occasions, the mask will summon a spectral Dragon Priest to come to your aid. Both effects activate the same way.
