When a token is inside the radius of a Light that is a darkness source OR when a token is inside a region that has a Behavior: Adjust Darkness Level that is set to 1:
The token cannot see tokens outside the region/light; however, tokens outside the region/light who have only Normal Vision can see the token that is inside.
Expected Behavior:
Light as a Darkness Source - A token outside the light should not be able to 'see' the token that is inside unless they have a sensory ability beyond Normal Vision and Darkvision.
Region with Darkness level set to 1 - A token outside the region should not be able to 'see' the token that is inside unless they have a sensory ability beyond Normal Vision.
In both cases the token inside should be detectable via hearing if within range.
