The bullets rock the arm backwards. The formation slows, or at least becomes much uglier, with more exposed bone and tendon instead of raw red meat. The change makes it harder to tell just how much the damage mattered, but considering that the monster isn't shouting obscenities or anything, the answer is probably disheartening. Much like the very slow growth of another arm.<br/><br/>Less disheartening, the burning causing that same matrix-y effect or the arrival of more backup. Even if it does surprise the shit out of everyone. Also not disheartening, the way the flames stay for a few moments as the spirit chars a bit of shoulder. Before the meat gets replaced, the bones can be seen for a moment.
