Night Vision, not Darkvision

So I'm having an issue when trying to set up dynamic lighting in my 5e AiME campaign, and it is the issue of night vision. In this setting the dwarves only have night vision, which is they can see in dim light as if it were bright up to 60, but they CANNOT see in darkness. Having trouble getting this to work as the usual method for setting up darkvision is to make the token a source of light, however this doesn't work if they are in darkness... Unsure if this has been answered elsewhere but wondering if it can be done

Hmmm. I can’t think of a good way to handle that. You might experiment with setting their multiplier really high and putting many tiny lights around the map. If you have them a multiplier of 10000 and had lights with a radius of .01, they’d see those as 100’ lights but it wouldn’t let them see in darkness. 

It's not perfect, but it might work for you.  You can tweak the radius and multiplier until you get the effect you want, and also possibly place the super dim light sources on the edges of so they aren't as visible to normal characters: Normal character (1x multiplier): Dwarf Character (10000x multiplier)
