Force Sense represents your general ability to rely on the Force in place of your natural senses and perception, and how attuned you are to the flow of it around you.

What does this expertise *not* cover?
No Points: Your senses are average, but not necessarily bad. You can sense life and strong presences or disturbances in the Force around you, and perhaps someone's emotional state if it is particularly strong, but you are unlikely to be able to pierce Concealment or Cloaking, and your senses of imminent danger are spotty. Unless you are a Miraluka or have practice from an early age, you are unlikely to be able to navigate well while blind.
1 Point: You have begun to expand your awareness in earnest. Your attunement to the Force allows you to more keenly and specifically pick out what you can sense around you, and you can tell a bit better when danger is afoot. With focus, you can somewhat more easily detect someone's general emotional state, and perhaps even penetrate the veil of attempts to hide one's self in the Force. At this level you are capable of using Force Sight (if you have learned it) to navigate while blind and 'see' via the Force, in a limited way.
2 Points: Your senses are sharp and you read your instincts well. You can sense most things around you at a fair distance, and zero in on small or faint things with some concentration. Your ability to feel incoming danger is fairly reliable now, though it is up to you to be able to react to it. You have a functional awareness of people's basic emotional states without too much focus, but with concentration you can try to glean impressions of deeper feelings.
3 Points: You feel the Force readily. You have great awareness of your surroundings and presences, you can read the movement of the Force to see an opponent's moves before they make them, and your ability to sense emotions is very good. You can navigate near flawlessly without sight and react to some things you might not otherwise see coming. At this level you can reach out through the Force to 'see' and observe distant places or people with which you are familiar (with staff oversight). Only those very skilled in hiding their presence are likely to best your keen senses.
3☆ (Mastery): Your eyes and ears are but pale imitations of the breadth and depth of awareness you have achieved through the Force. You can feel everything around you in near-perfect detail, feel even minute uses of and disturbances in the Force, cast your sight to truly immense distances, and seem to always know what people are feeling around you. When it comes to danger sense, you practically know what others are going to do before they know themselves.
