[Quiet Man Cometh]

Yeah! One of Na'lsa's prevoius meals can chew its way out of his back and attach itself to (what's left of) Mathias' face! And then when Mathias' holy light thing sears it in half the legs explode on his robes, then the upper half can extract a couple extra limb from Na'lsa's left-overs, stick them into it's torso and then walk itself over to Innon while the entrails that fell out of it can wiggle their way up the crosses and start freeing the other undead!

:D


EDIT: or, they can all erupt into black flame.
