I'm statting up a very smart character for a hunter game (Int ••••) and would like to represent his ability to look over some theoretical work (briefly) and become an 'instant expert'.
I've noticed an ability of the same name exists in Changeling and Genius, but from the summary I read it doesn't seem quite right. I also know we of the encyclopedic knowledge merit which is certainly close but only represents a single fact (correct me if I'm wrong).
What seems appropriate is a merit granting an extended intelligence based skill check (fixed target number) to gain either •s in merit as dice towards a skill, or successes from the extended roll up to a maximum of X rolls (before it becomes down time XP expenditure) for a single check, once per day/scene/chapter. The alternative is to make it a custom endowment for my Hunter ... but an endowment is just a hunter-specific merit so that's no big deal in any distinction.
My question is, is there something out there that does that or similar already? If not is my proposal sound and not can I finalise the details and to what • rating?
