"If I want to blow just the hinges, I'd have to use one of my smaller, more precise devices. They work by emitting high-frequency sound waves, though, and won't work in the area of your spell. To blow it up, now, I'll have to use a larger explosive that isn't sound-based, and that's going to be noticeable for more than just the sound it would have made." She seems to be weighing her options for a moment, before continuing, "But someone's going to need to bring down our mighty foe, a Door, and it might as well be the Lady of the group."
Kana moves over toward the door and plants a small cluster of green explosive packages on the door. She backs up to where the group is, then ducks behind Greed and hits the trigger.
[spoiler]Planting Acid explosives on the door, since from what I can tell from the SRD, hardness shouldn't apply to acid damage and acid does normal instead of reduced damage. What's the door made of, by the way? That might determine how many explosives I'd have to use to burst through it. >_>[/spoiler]
