Everything

• The difficulty for this feat – as detailed in the Uncanny Influence section, p. 116 – is that opponent’s Willpower Trait, if the opponent is a normal human being, Willpower + 3 if the opponent is a mage or other Night-Folk critter (vampire, werebeast, etc.). Hence, it’s easier to influence normal people than it is to have the same effect on Black Suits, vampires, and other unusual antagonists.

• If he’s trying to discourage or enrage several normal human beings, then the difficulty is based upon the usual coincidental, vulgar, or vulgar without witnesses. Generally, this is a coincidental feat, especially if it’s backed up by some impressively badass glare.

• If he’s trying to discourage or enrage a bunch of Night-Folk or mages, then the difficulty is the highest Willpower within that group (or a default of 5, if no one in that group has a Willpower of 5) + 5. As detailed under Uncanny Influence, that strong-willed leader dictates the reaction within her “pack.”

Ideally, the mage can simply stop a “casual opponent” – that is, someone who’s not seriously intent on violence – before things get out of hand. One or two successes will most likely have the desired effect.

For details about overcoming a seriously dedicated opponent, again see The Basics of the Uncanny Influence section.
