This is a PS3 Glitch, after learning the words for the shout to Summon Durnehviir, I am unable to use the shout. when I attempt to use it, it does nothing, no shout at all. Going back to earlier save ius not an option because of the length of time from Soul Cairn and the first time I tried to use the shout is extensive. Has anyone had this experiance, and does anyone have a possible fix?
Durnehviir appear on the ground, differ from Odahviing, which shows up in the sky. Durnehviir should be summoned in open area, outdoor area is better, though it could be summoned indoor.
This happens bacause the "Summon Durnehviir" shout acts like a conjuration spell, and this kind of spell have to be cast at the ground, like "Conjure Flame Atronach".
I have a similar glitch. Everytime i shout at the ground, the screen flashes purple, but Durnehviir fails to be summoned, and i still have to wait for the 5 minute shout timer to cool down. Can't believe PS3 users are also having to endure shit like this even after months of delay.
