Could this be revisited? Currently, you can't disarm or pick boxes when invisible. I think it is very IC for a Necromancer or Thief to hide invisible while tinkering with a box since you're pretty vulnerable (no armor, etc).

If you blow a box, sure, your spot would be revealed. And I'm sure there would be some clicking noises as you worked. But I don't see why it would automatically pull you out of invisibility.

Thanks,
