Obstacles

  • Ob 1 situations are easily overcome by a single guardmouse.
  • Ob 2 situations are the bulk of the Guard’s work. Any single mouse should be able to do it alone, but there’s a slight risk involved.
  • Ob 3 situations are challenging. You might need help to overcome this problem. You’ll encounter a lot of situations like these during your time in the service.
  • Ob 4 situations are downright hard and all but require teamwork, if not a stroke of luck.
  • Ob 5 situations are very difficult. Overcoming them requires dedicated teamwork or a combination of Nature and skill.
  • Obstacles can be 6 or higher, but those are for extreme circumstances and will only rarely occur.
