(This match is surprisingly thematic. Kudos.)
I should probably mention, Roland might be getting his own Instinctive Reaction added to his profile, depending on whether or not
this CRT goes through. Even then though, his gunslinger training revolves around using his mind, body and instincts to the best of his ability instead of relying on his guns and firepower to win things out, so Instinctive Reaction alone probably won't be enough to win against him.
Anyway, she had better be
really good at reacting and dodging if that's going to be the core of her gameplan, because
this is one of the things Deschain can do mid-combat, and he's capable of firing and reloading fast enough to look like he's continuously firing a machinegun. Mid-Low regen doesn't seem like it's enough for a
Wall level character to survive being shot in the head with a gun that has a
Small Building level+ calc resulting from its best feat, and he's capable of some ridiculous bullet-spam whenever he's fighting seriously. (Which is about 98% of the time, lowballing it)
By the way, I know nobody mentioned her ability to turn into a bat, but she's
going to die if she tries that against the Gunslinger.
