Normally, the Sentinel would just smash through it with a halberd. But metal makes that a bit more difficult. So she knocks around on it quietly, trying to gauge where it might be weakest. Hmm, kind of a solid metal, whatever it is. But the frame seems to not be as sturdy...especially the hinges.

Stepping back, Nephenee lines herself up, and swings her halberd hard on the verticle with both hands behind it. But her halberd isn't as strong as she's used to, and they're showered in shrapnel as it shatters on the second hinge! Being right there in front of it, she takes the brunt of it, and earns herself more than a few cuts to the arms with a sharp hiss of pain. If she hadn't reacted by letting go of the shaft on the bounceback and throwing her hands up, that could've been a lot worse!

Whoops.
