Like Tedronai said, those examples can me mental and social, and it depends on what purpose they serve. That is decided when entering the conflict.
In the examples, I could get into a mental conflict with my opponent, snarking and intimidating each other, to make him less confident in himself when the actual fight starts.
Or, if he and I are the leaders of a group, the initial snark could be intended not to shake the opponents confidence, but his status among his peers. It would be the exact same conflict with the exact same rolls, but it would be social stress instead, because the focus of the scene is different.
The same goes for the girl in the bar. Let's say she's a friend of my ex, who wants to hurt me, because I dumped her friend. This would be a mental conflict.
If, on the other hand, her plan was to humiliate me as revenge, make me act like a fool in a bar I visit frequently, it would become a social conflict. Again, the exact same rolls, the exact same scene, but on a different stress track.
I am using a narative spin that you all want me to use. I have already given my MECHANICAL reasoning behind it and what it does MECHANICALLY. Just because I cant NARATIVLY describe it in a way that you all want does not make the attack wrong or not working in the way that you view it. I understand that this game is a NARATIVE game, yet when making things one must look at the MECHANICAL side of it or else you will never be able to make anything. Every power, every stunt, every attack has a MECHANICAL side, even if the NARATIVE varies between users.
Yes, but you are still putting the cart before the donkey here. Different narrative descriptions can be pooled into the same mechanics (and vice versa). That does not mean, that it is a good idea to start with a mechanic and wrap the narrative around it. It will almost always be wonky at best.
I will do my best on this: In an attempt to overcharge and drain his opponent Jimmy uses an attack that will inject spiritual energy into his opponent. With a few quick light touches, he injects the energy into what he believes to be focal points for spiritual energies, in an attempt to disrupt them.
It's not the best, but it'll do for now. I agree with Tedronai, this is pretty disconnected from what you are trying to do mechanically. As a magically enhanced martial arts attack, a physical attack, this would be just fine. As a mental attack? I just don't see it, sorry.
Besides that, I believe that conflicts should stick to one type and only involve the others as maneuvers. I don't know if it says so outright in the books, but I believe it is at least implied, when they talk about setting up a scene. This is one of the problems I have with your idea, that it crosses this line. What happens, when a wizard is taken out mentally by your attacks? He will still fight you physically, since he is not taken out there. You would be fighting two separate conflicts at once, that just don't go well together.
I just had another idea of how to make this work. Kind of mix and matching a lot of ideas that have been there before.
An anti-magic grapple.
Works just like a normal grapple, using fists instead of might. Since it involves shifting magical energies around, it should probably be at least a -1 power to allow it, instead of just a stunt. Here's how it works:
1. Put up a maneuver on the target, just like you would for a normal grapple (for example "blocked chi")
2. Invoke that maneuver to enter a grapple. This will however not be a real, physical grapple, it will be a magical one, meaning it blocks only magical actions.
3. Each subsequent exchange, you roll fists to keep up your anti-magic-grapple.
Standard grapple rules apply. That means you can inflict 1 shift of physical stress as a supplemental action, each time you roll to renew that grapple.
So with the maneuver, you strike the target and shove the first batch of energy into it, preparing to cut him off from his power. After that, you strike the focus points again, charging them with even more raw energy, overloading your targets systems. Slightly altering your strikes, you can make the overload so painful, that he will eventually black out from the pain. You could even use that pain to force your target to move in a certain direction (the "move your target one zone" action of the grapple rules).
So, what do you think?
