My group just did a session where they used scene declarations and assistive actions to take out opponents more 'powerful' than the group, and it was awesome. It worked well, giving even 'social' characters the ability to be nasty.
But now he wants to extend that to take on an even more powerful foe, by taking the time to do lots and lots of prep work and lay the ground for a massive social attack. In some ways I love the idea. In other ways, I look at the idea of +24 in free invokes and, as a DM, I go 'something is just plain wrong here'.
Am I missing a detail somewhere on declarations, and the free invokes they can give you?
For scope, the character he's attacking is a Red Court Noble built vaguely like Marcone -- while she can fight, she prefers to make her attacks social. She can kick some serious butt at need, but views it as crass and below her station.
