The unarmored skeletons all go down; a few remain twitching, but the damage is enough that unless you walk over or through them they're not a threat. And even then, it's more a threat that you'll be stopped or fall than any one injury that might happen from the literal ankle-biters.<br/><br/>No, the big threat is that with the aid of the armored skeletons, Pain has ripped a strange glowing tooth out of the ground. It's probably long enough to use as a dagger and it probably radiated magic even in meatspace. When it goes into Pain's body, it starts producing skeletons to the tune of lots per second. They're still just as ready to fight with anything, so more than a few start fighting each other right after appearing. But this also produces a nice wall of bodies as she tries to get them to cover her carried approach to the motel.
