Is there any way to get adra dragon scales if you do what it wants?

She says her old body dies but it doesn't appear to leave its corpse anywhere. Is that a glitch?

[drumther]

Nope. Unfortunately, the Adra Dragon just dissappears afterwards

The game isn't very nice for the greedy or soft-hearted. I can think of one instance where you don't get anything for killing a person.

 

Actually, I think the rule of thumb is: whichever takes more effort, yields the higher reward in Pillars of Eternity. If you can kill someone straight away or do a quest for him, (The ogre in Endless Paths) more reward. If you can talk someone out of something, or kill him, killing may give you more. (Sky Dragon).
