So I've been playing a bit recently and following along via my Kunark prima guide for information since I enjoy the feeling of opening up a book versus going onto the wiki.
I was excited to see that Rangers were supposed to get Instill Doubt at level 22. I mentioned this to someone else recently only to find out that this wasn't the case and that Instill Doubt isn't a ranger skill?
I found a pdf version of the Ranger page in the strategy guide and took a screenshot of it for reference which can be found here:

Was this removed at some point or perhaps this was an error in the printing?
