Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General Certain skillbooks not on vendors. Ever.

I finished the game now and still no dust devil (Level 1 Skill). I have never seen it and checked all vendors every level. This book just isn't in the game at all. I also used a save and load trick before talking to vendors to reset the items over and over. I managed to get whirlwind from a static world drop but still it hasn't showed up on vendors.
