Was Dust Devil a rare book? It's possible I missed one, since the Links file I looked through is cluttered. I'll look into that later when I'm able to.
As far as I know Dust devil can only be obtained at the start of the game through character creation (or a savegame editor). The skillbook is not present in the game world nor any warrior vendor sells it. Maybe the skillbook itself doesn't even exist in the Divinity Engine Editor, we'll see.
