How to summon Durnehviir?

So I've got the shout in my shouts list and I've unlocked all three parts of it, but I can't seem to be able to use it all, just the first part.

Am I missing something? I still have a quest for 'Learn the first word of Durnehviir's shout' but it's showing as me having already got it.

What gives?

Solution 1:

Shout at the ground when using this shout. If done correctly he will be summoned immediately on the ground where the shout was directed. Be sure to press and hold to cast all three words to the shout or it will not work.

Additionally, from the Wiki:

The miscellaneous quest inventory indicating an open quest "Learn the first word of Durnehviir's Shout" is actually referring to Soul Tear, an entirely different Shout that Durnehviir will teach to the Dragonborn, one word at a time, during his first three summonings. Only after that will Durnehviir be of any real use in battle.

Solution 2:

It took me 2 hours of searching online and walking around shouting at the ground.
Here is how to summon him. Its simple and you will be slapping your forehead(I know I did).

The shout he gives you in the Soul Cairn is "Summon Durnheviir" (obviously).
This shout (unlike all the others) takes three dragon souls to unlock it completely.

Very important: it is a three part shout!

I am over emphasizing this because it seems to be the one thing the other forums I read do not explain. I only had 1 unlocked so it wasn't greyed out in my list of shouts and appeared to be usable. Not the case!

Again: It will not work until you spend 3 dragon souls to unlock all three words of the Summon Durnheviir shout.

Once that is done, go to a open area, relatively flat and shout at the ground in front of you.

You don't need to be in combat nor do you have to be on completely flat ground. Just a open space with no trees. (Mammoth camps or farms is a good place.) The area outside of Whiterun is where I did mine.

Shout at the ground in front of you and when he appears, he will give you one word of the soul tear shout. He will then fly off and circle you for 5 minutes. (You can use the wait function to speed this process up).

Shout again and he will give you another word. Same process except you have to wait a couple hours. Use the wait function again. Shout a final time and you're good to go. Hope this helps.
