I've never figured out/looked up how to save Siegmeyer, much to my overwhelming shame. He's such an awesome character and I can't save him/don't know how!!!!11!
You have to visit him in like 4 areas (in order) to save him or whatever. I've done it once...by accident.
Oh I know all about his storyline, where to speak to him/Sieglinde, but there is something that I'm either doing or not doing that seems to seal his fate. Think it might be something with Sieglinde's dialogue, something about not speaking to her more than a set number of times... need to look more into this.
But still, I am disappoint...
