How could i stat an advantage/item that gives me bonus damage to specific creatures once i have studied one of them. How this would work is: The first time you meet a Magewrath Dragon (small dragons with a nasty bite that appear out of nowhere to feed off magical energy in my game world) you cannot target any specific area on its body. Once you study its corpse and/or study its behavior in combat you can target areas like vitals when you next fight one and you get +1 per die to your damage against them. Studying a corpse preserved in a lab or killed by someone else requires an IQ roll for the same effects.

Im really not sure how to build this so any help is appreciated
