Just some thoughts on this talent. As worded right now it seems like this talent does nothing unless you have a very good GM that will specifically build identify rolls into an encounter if one of his players has this talent. There isn't anything like this really covered in the rules and it seems like this would be something that would fit better into an obligation type category, something like "each rank of this talent reduces your obligation rating by X for the purposes of rolling obligation at the start of the game."
Granted it thematically works better with certain obligations like bounty, or debt, but it is not too much of a stretch to make it work for all of them.
I will say that I do enjoy this talent and talents like this that are not overly mechanical and more flavorful and cinematic, It just means that the GM has that much more to be aware of and weave into the campaign.
Perhaps if the talent stays worded as it is a minor sidebar could be included in the rules somewhere that deals with identification rolls based on the groups/individuals Obligation or something of that nature just to give some guidelines. That way the GM's are happy because they have something to work with and the players are happy because they feel like the GM is not just arbitrarily making stuff up and rolling against it. In a perfect world this wouldn't be necessary as the players and the GM would work flawlessly together to create a masterful cinematic experience but alas it is far from a perfect world.
