So in my game I have the players have a certain light source for there token that they can only see. Torches, candles and the such give off a light source that can be seen by anyone that has line of sight. Now many times my players will pull out a torch, carry it around, far hand it and move it around with their powers. To make this easy I have torch tokens that can be controlled by everyone. The problem that happens is that they don't need line of sight to it to see it since its "Controlled" by everyone. Is there a way to fix this. So that they can control a token and still need line of sight to it to see its light source?
