Mikasa Extra Sheet+Swift Actions

As a swift action, you may identify a creature’s weaknesses (DC 10 + creature’s CR) as described under the Knowledge skill, but may substitute a Perception check for the appropriate Knowledge check at a -5 penalty. This only reveals the target’s weaknesses, or lack thereof, (such as damage reduction types and vulnerabilities), and does not reveal any additional information about the target. Once you have succeeded at a scout attempt or Knowledge check against a target, any talents or effects that require you to scout a target may be used against the target for the next 24 hours; after this period you must successfully use the scout ability against the target again to continue benefiting from related effects.
