Spinel's arrow was ready now, and she had been steadying her aim for the past minute or so.  Her rubble was maybe about 50 feet from the action, not a terribly unreasonable length to make an accurate shot from.  She let her arrow fly at the spiderbot trying to kidnap Amber's gem.  The shot was powerful enough that the recoil caused her to almost fall over, and it destroyed her pile.  She really hoped that her shot met its mark, because she was now visible and a sitting duck.
