Everything

You have taken the time to learn about and specialize in one particular enemy of your Sect. You are aware of at least some of the group’s customs, strategies, abilities, and long-term goals, and can put that knowledge to good use. This Merit is worth a -2 difficulty for all non-combat rolls pertaining specifically to the subject of your specialization. On the other hand, you are at a +1 difficulty when it comes to dealing with other enemies, simply because you’re so thoroughly focused on your field.
