it seems like durnehviir is completely useless... every time i summoned him, he just kept unsummoning himself, even if im outside in the open.

i even tried summoning him in battle, and he still refused to attack anything, and just vanished shortly after.

now, i admit i havent summoned him lately, i pretty much gave up on him awhile ago... so maybe i just got VERY unlucky with the spots i summoned him and everything, who knows.

the first three times i summoned him, though... he'd barely finish talking before just randomly vanishing... which got annoying, cause i couldnt even hear him tell me about the shout.

i also tried summoning him in the forgotten vale, i think its called... which seemed like an outside area, so i figured he'd fight there... nope... just looked at me getting attacked, then vanished.

was i just getting unlucky, or... is he just glitched?

im starting to think its just on my end... because the UESP wiki doesnt mention anything like this, other than him unsummoning himself in tight spaces/interiors.

so, has anyone else had problems with durnehviir, or did i just have bad luck summoning him?

im tired of trying to summon him and leaving myself unable to shout for so long.

In short his "spawning" is very buggy...

Sometimes it works, or not.

Increase your chances by using 100% flat areas (not a single stone that might F-up his pathing).

Yeah, I just summoned him for the 3 Words of Power and let said goodbye to him.

Odahviing is better anyway.

ok, tried summoning him a again a few times... well, he actually flew off into the sky and stayed with me, and when i encountered giants, he fought them... for maybe 10 seconds... then he was gone when i turned back around to see if he was still fighting the other giant... does he just randomly vanish for no reason mid-battle, or does he actually have a limit to his health unlike odahviing, and can be defeated very easily?

since he doesnt seem to have a time limit, and it doesnt matter if enemies are around or not... i assume its the health thing, unless he's completely gltiched and useless.

if it is the health thing... then... durnehviir kinda svcks.

even if you manage to get him to stay and fight, one or two hits and he's gone... what the hell kinda cursed undead monster dragon is that?

Sounds like a glitch. I summon him, and he appears on the ground. If there is no immediate threat, he hangs out and thanks me. If there is an immediate threat, he takes off and brings down hell for all who oppose me.

He lasts for a really long time thats for sure. I didn't time it, but it seems like about three or four minutes. You cannot shout when he is aloft, so that kinda svcks.

The only thing is, sometimes he gets distracted, and he will attack two mudcrabs OVER THERE, when there are Thalmor or Giants in my face OVER HERE. GET HERE MOTHA!!

Maybe he is getting distracted?
