Ghostgate Shrine Blessing

The Ghostgate Shrine Blessing can be received by offering soul gems at the Ghostgate shrine in the Red Mountain region. Once within the ghostfence, the shrine can be found by following the main path to the north, and turning east at the first opportunity. Using the shine will sacrifice one of each type of soul gem in the Nerevarine's inventory (excluding Azura's Star), whether or not they contain a soul. To avoid losing multiple gems, simply drop all but one, then pick them up again afterwards. The blessing lasts 48 minutes, or one full day in game time.
