Okay so these have likely been mentioned in the Errata thread, but I'd like to spawn a side-topic on what the hell we're supposed to do with these.
Re: Locksmith and Lockpicking, I'm assuming these are supposed to be the same skill "Locksmith" and mention of Lockpicking is just something that didn't get deleted.
Re: Arcana -- what does this skill do? It's not mentioned anywhere in the book, except for it existing as a skill. Did this get overlooked, or is it a "will be useful in the Magic book" skill that they included in the main book so that people won't have to fix their characters later? What gives?
