Characters with darkvision in D&D perceive complete darkness as dim light and dim light as dark vision. I'm not sure if there is a way to cause this effect or if it would be worth posting as a suggestion (if it has not already been done?). What do you think? I think Ideally I'd like to toggle on night vision, and have that character see as if in dim light, and see dim light as bright light, and bright light as normal bright light as well.
