For guys here who haven't finished the MQ yet. I've been curious, if you can use Bend Will to control dragons would this work on Paarthurnax? Odahviing? Durnehviir? Or even Alduin himself? Think about it. It would be pretty cool to try. I'm a PC player but I've been quite curious if you can use this shout on those dudes mentioned.

It works on Odahviing.

You can't use it on parthy or alduin. I've heard it works on odahviing. Don't know about durnrehvir

I couldn't get it to work on durnahviir. Probably because he's part of Dawnguard.

Thanks for the info! Kinda bummed you can't use it on Paarthurnax and Durnehviir. It would probably be cool to see my character riding them,

Paarthurnax and Durnehviir... the Ford Pinto of dragons.
