"XXX extraordinaire" talent

[Fidoric]

I was thinking of a talent allowing to gain an extra boon point if you earn one. Such a talent would be tied to an individual skill.
For example, a "French cook extraordinaire" earning a boon point from a high roll would get a second boon point from his talent but only when making a Cooking roll.
I feel it could be a good way to make characters more efficient with one skill. OTOH, some skills are broader than others and this could be abused. A "Spellcaster extraordinaire" would gain this benefit each time he casts a spell. Or maybe this talents could be tied to an individual spell ?
Anyway, I feel this should be a costly talent (10 CP ?).
Any input ?

Sounds interesting. I will definitely consider something along those lines.

Thinking a little further, I think that such a talent would be better if limited to general boon points (no combat or casting boon points) IOT avoid killing machines or monstrous spellcasters.
