You cam steal skill books, other items from NPCs (i tried it in the main prison camp) by getting them in a conversation with one of your characters then clck on another character with sneaking, go behind the npc, activate sneaking and proceed to loot.

After some consideration, I added this to the list, after all. I decided that whether or not I considered it to be an exploit was irrelevant, as, either way, it's still something you can do in the game, and as long as Larian decides to leave it in, it's up to the player as to whether or not they want to use it. Larian did decide that being able to learn abilities of types you haven't spent any skillpoints on was an exploit, and thus removed it, and I had that listed. Also, it's probably better if I don't act elitist about... anything, really. Nobody wants to agree with an elitist.
