When choosing a skill with a subset of choices (such as Craft, Perform or Profession), does an unchained rogue with the Rogue's Edge class ability (Pathfinder Unchained) need to choose only one subset, or does the benefit apply towards any/all of the skill's subsets?
Now, I know that the Signature Skill feat grants something similar, and specifically states one must choose a skill subset, but I see now such language for Skill Unlocks in general, or in the rogue's Rogue's Edge class feature--which is supposed to be more versatile than the feat anyways.
