It changes every time you level up for me. As for Walk in Shadows, I STILL AM HAVING ABSOLUTELY NO LUCK WITH IT. I QUICKSAVED-QUICKLOADED BEFORE CHECKING the stupid inn merchant's inventory (changes) every time) AT LEAST TWENTY TIMES AND I STILL HAVEN'T GOTTEN THE stupid book to spawn.
It's not just incredibly annoying, it's just outright stupid. I am lone wolf'ing with a ranger/rogue, and the Walk in Shadows is IMPERATIVE in my strategies. Instead, I'm forced to fight battles by using a flee strategy, being forced to gimp one enemy at a time and then flee because of the book won't spawn (I tried, to get it to spawn, it's obviously not there).
