With the Perfect Instincts and Ice Cold moves, they're taking +5 to two of the basic moves and a +2/3 to Seize by force.
Could you possibly show your work here? I'm not seeing how any of this adds up.
Like math class... :)
So if you really want to min/max the battlebabe, there are, like most classes, several ways to go. You're gonna want one of the stat blocks with Sharp.
(As an aside, sharp is bad ass, since the bonus to reading a sitch is on going as long as you're using the MC's answers. Vincent even made where the Angel gets +3 Sharp a class improvement, rather than a move another class could take like the Brainer's Preternatural at-will brain attunement or the Gunlugger's Insano like Drano.)
So now you've got +1 Sharp and Perfect Instincts, right? That gives you a +2 when acting on the MC's answers to a situation you read. This means that when you're Acting Under Fire while using the MC's answers, you're rolling+3 Cool +2 = 5.
You've also got Ice Cold. This means that you use Cool to Go Aggro, at least on NPCs. When you read a situation that gives you a +2 to Going Aggro, so that's rolling+3 Cool +2 = +5.
Same with Seize By Force. You get that +2, which if you take the +1 Hard improvement, that's +3. If you take the Gunlugger's Insano Like Draino, that's +4.
Now you can't go up to a Gunlugger in the middle of the street and win a knife fight, but when the Battlebabe sneaks around, comes up with plans and executes on her plans, she's a beast. You're gonna want to take that +1 to sharp when you can, of course.
Say, for instance, you take a long machete blade with a hole punched out of the bottom with a long chain tied to it. That's a machete chain (3-harm hand area). With Merciless (+1 Harm), you could be rolling+5 Go Aggro to force a room full of guards down. If they force your hand, you'd be doing 4-harm to everyone in the room, ignoring the gang bonus because your weapon has area.
Now the Gunlugger can be similarly combat-maxed, but the Battlebabe is not too bad at social stuff as well. It's my favorite character and as soon as I get a chance to play rather than MC, I'm gonna jump all over it.
