Lily was kind and charming, but manipulative. That's Rapport, Empathy, and Deceit right there.
Her enormous power makes her very dangerous, which easily justifies a decent Intimidation skill.
That leaves Presence and Performance. Her power and general social acumen guarantees a decent Presence, and she was a professional model once.
So I'd say she doesn't have a social skill below Fair. OW is more or less with me there.
Actually, yes. Driving, Burglary, Scholarship, Craftsmanship, Might, and Guns. All off the top of my head, should all be Average at best, and Mediocre in many cases.
She's a faerie. Supernatural strength and grace, right? That should cover all of those.
To some degree, sure. But it doesn't help you speak Etruscan or Ancient Sumerian, nor does it help you shoot a gun right.
Who said anything about languages? And it does help you shoot a gun right...remember what Harry said in Cold Days about Sidhe grace and aim?
Okay, what about the Senior Council? They don't strike me as all having Average or Fair Might, just for example, and surely you don't argue Kincaid's a higher power level than them?
Much better example!
(Even though they're actually old enough to have Inhuman Experience more-or-less by default.)
Still, there's no Senior Council member that's definitively bad at anything. The Merlin may never wrestle, but he's ancient and he's got supernatural vitality. Plus he's generally badass.
So while I'd be fine with a Merlin that has Mediocre Might, it doesn't bother me at all to have a quirk of game mechanics give him Fair Might.
Good would be too much, though.
