|Heroic Action Role-Play|
Your sight is heavily impaired, to the point of blindness or near-blindness. Of course, this being Action, you are not helpless in a fight - you have developed means to compensate. However, you still cannot discern images, read text, or "see" things other than rough shapes. Anything beyond your Mind in meters away from you is "out of sight" for you. Snakeyes rolls on actions where your lack of sight could impede you always fail.
Someone blinded and who has not had time to adjust to his condition cannot move along with a Basic Action, and only moves his normal Move with a Full Move action. Similar to the Static weapon disadvantage.
