So I created a macro that uses the TokenMod API (thanks Aaron). When my PCs fall unconscious, I click and the world goes to only the Advanced Fog of War memory they had. !token-mod --set light_losangle|0 !token-mod --set statusmarkers|+sleepy When they wake up, it goes back to normal. !token-mod --set light_losangle|360 !token-mod --set statusmarkers|-sleepy By using the radius of vision I don't have to mess with their darkvision and it works on those without darkvision who are using other light sources.
