Players may enjoy a teamwork bonus, sure—but why not give your big bad a complementary solo bonus when they’re the only one facing the heroes?

There are a few ways you could implement a solo bonus. You could use more than one of these, but be careful when combining them as they’ll add up fast.

• The big bad gets a bonus to skill rolls that’s equal to the group’s maximum potential teamwork bonus (page XX) — the number of PCs acting against the big bad minus one (so a +2 vs a group of 3, etc). This bonus can’t do better than double the big bad’s affected skill, though, just as with PCs (or maybe you’ll break that rule too).
• The big bad may reduce the stress of successful attacks by the number of opposing PCs divided by two, rounded up. If you’re worried this will make the fight run too long, then hits reduced this way can’t be reduced below 1.
• The big bad has amplified invokes: when making a paid invoke of an aspect, their bonus is equal to the number of PCs they face. No such luck with free invokes, but this makes every fate point spent utterly terrifying.
• The big bad may suppress invokes: when facing two or more foes, the opposition’s invokes only provide a +1 bonus, or allow rerolls only, when used directly against the big bad. Optionally, the big bad might also remove the PCs’ ability to stack free invokes.
