   * You hit the dragon. It's a curious way to commit suicide.
   * The dragon lunges to bite you while at the same time whipping
   * its tail in your direction, and clumsily manages to latch onto
   * its own tail instead of you. The dragon screams in pain!

   * <strong>Hit</strong> a
   * {@link adventurejs.Tangible|Tangible}
   * {@link adventurejs.Asset|Asset}.
   * Requires that the Asset to be hit has
   * asset.dov.hit.enabled
   * set to true.  By default, no special results will occur.
   * Authors wanting to make use of it may need to use a method such
   * as verb hooks. See
