OW, Jack's never been right next to one of those when it went off before, so he has to shake his head briefly. Still, there's a lot more smoke coming out of that thing now than there was before. All right.

If the goal is to keep the thing from getting in to the building, then Jack has to try for a Break attack. His sword briefly charges before he slices, but he can feel the magic dissipate off the Red Scorpion's hull. Petrify? Not a thing that'll help.
