If shadowbending existed, what do you think it would be like? I think it would be a psyhcological subskill of airbending, by which you condense the air a bit, causing it to appear ever so slightly darker. The person your bending it at, however, knows you are a shadowbender, yet does not know what that is. This causes him to believe that you are actualy bending shadows and to percieve the slightly condensed air as much darker. Because he believes you are bending shadows, he then believes that the shadows can hurt him. His fear of the dark is intensified, and more importantly, he will react to your shadows like they're tongues of fire. He may even convince himself that they burn, causing him to feel pain when they touch him.
