Three Times a Lady

Why did you give the Morrigan Manipulation? She has almost no myths about being sneaky, and is about as subtle as a rock even when she uses animal forms to harass people. She has more than a dozen myths about being blunt and having a forceful personality and making people love her (she only failed once). That definitely sounds way more like Charisma than Manipulation.

Ah, navigating the choppy waters of social Epic Attributes.

I'd have to disagree strongly with giving the Morrigan Charisma; she's pretty much entirely the opposite of Charisma. While she does indeed have a forceful personality - she knows what she wants, is not afraid to tell you about it and will probably fucking shiv you if you don't give it to her - she does not ever use that personality in any way, which is really the key for Charisma in our opinions. She's definitely not well-liked or -respected, even by her own pantheon, who avoid her whenever possible (which is understandable; she's a crazy lady who foretells doom and wades in blood, that sort of thing). She's also definitely no leader; she doesn't inspire followers or even intimidate them into doing anything and tends to lone-wolf it up whenever she's hitting the battlefield. I'd say that "making people love her" is misleading as well - she certainly makes people have sex with her, usually by threatening them or promising them rewards, but they're not doing it out of love. Sexytimes with the Morrigan, in myth, has everything to do with lust, power and not wanting to get wrecked later, but it does not have anything to do with love.

So we put Charisma on the "do not ever ever give this to this person" list for the Morrigan pretty early on. Charisma doesn't always have to be fluffy bunnies of love and friendship; it can refer just as much to hardassed respect, inspirational leading or a certain je ne sais quoi of always being the focus of attention, but just being a thoroughly unpleasant person isn't enough to qualify for it.

Manipulation, on the other hand, is a more complicated issue with her. You're 100% correct that the Morrigan is not subtle when she talks to people; she pronounces prophecies, threatens, or states what she wants, but she never tries to maneuver the conversation around with tricksy politics or anything. For us, the Morrigan gets Manipulation because she's the most badass undercover agent in the history of the Tuatha. You mentioned above her shapeshifting craziness, which usually involves her throwing herself at somebody, and you're right, being charged by a cow is not subtle, either.

But the key here is that nobody ever has any idea it's the Morrigan doing that. With the exception of the wolf/heifer situation, wherein she specifically tells Cu Chulainn ahead of time that it's her, nobody is ever aware that the Morrigan is fucking with them until she says the ancient Irish equivalent of "Gotcha, bitch". Take Cu Chulainn healing her, for example; without her specifically telling him ahead of time that it's her, he has no idea that the old woman he heals of her wounds (wounds he personally inflicted, yet) is actually the goddess until she tells him (which is further illustrated by his hilarious ancient Irish utterance of "Goddamn it, I would never have healed your obnoxious ass if I'd known it was you"). Cu Chulainn can't see through the crone disguise to avoid letting the Morrigan break his geas and effectively kill him; the Dagda has to ask who she is when he meets her as the Washer at the Ford. Shit gets even more crazy if you ascribe to the scholarly theories that think various other figures in the Irish sagas, such as Macha or the Nemain, are actually the Morrigan in disguise as well.

It's definitely a little weird-looking for someone as blunt and willing to stab in faces to be associated with Epic Manipulation, but that's where we ended up after examining her stories. The Morrigan does not have a subtle personality, but the fact remains that in Irish myth, if she wants you to be tricked, you are abjectly tricked. She may not feel the need to use Manipulation very often (why manipulate when you can just murder, am I right?), but when she does, she's always impressively effective.

I would note that, depending on your view of the Morrigan and what she does, you could rule that she has either Illusion or Magic to cover all the crazy shapeshifting shenanigans. We didn't end up going either route; Magic seemed ill-fitting since all her Fate-style connotations seem to be bound up in Prophecy (more likely that she just has Beast Shape), and Illusion, while a possibility, seemed again like she probably just had a few boons from it rather than the avatar of the entire purview.
