Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Beta Way of the Rogue Skill Books?

Hi guys. So I read in the changelog that they added Way of the Rogue and some skill books. I have found one in game but can't find which merchant sells them. Is there one?

My shadowblade isn't really fun to play at all if I can't get any extra skills for either witchcraft or rogue

It's not explained well - and it should be - but the Witchcraft/Rogue merchant is upstairs in the King Crab Inn in one of the rooms.
