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

I have the same issue, couldn't get Strong Regenerate. Was told that vendor inventory refreshes and updates itself to scale to your level every time you level up. I believe this is true. Now every time i level, i will make an effort to visit all vendors, even if i'm mid way in dungeon.

Btw for Whirlwind, i got 3 from the Commander in Cyseal, one book after each level up from levels 4-6.
