Yup always nice to have more people with eyes on the book. It gives a lot more detail and more explanation for things.<br/><br/>Since it's a fine item, I would assume that it does two things. 1 give you a bit more control when using adept abilities, this is a bit more of a narrative bonus so MP would have to rule on that. And number 2 it would boost your tier by  1 when using adept abilities.<br/><br/>So, basically all other factions have a tie level and the crew starts at tier 0 and goes up as the crew gains more experience.  So if the crew tier was 0 the focus would let you act as  if you're tier 1 instead when using your adept abilities. This would allow you to use your adept abilities on equal footing and to full effect when going against a person or obstacle  from a tier 1 faction, give you a boost when using your adept abilities against those from another faction that is tier 0, or lessen the penalty by 1 when dealing with factions that are tier 2 or higher.
