Darkness (not Darkvision) aka token emits darkness

Many times I wish I could surround the party with a darkness effect from NPC, OC or Monster Abilities, only to just have to turn off their vision, I feel it would be better to just have a click toggle for emit light/ emit Darkness to simulate that effect or to put a place token on the map with a darrkness radius.  It would temporarily cut anyone's vision that walks intot he aura. urprised I haven't seen this yet

This is a great idea.  I HATE having to stop a combat to change a token's vision settings, only to have them move out of an area of darkness and have to update it AGAIN...and then have the bad guy move so that I have to update vision a 3rd time.  It all works, but it's super clunky in gameplay.

Literally just came up in a game.  A monster in 5e D&D had a darkness radius and none of us had a way to counter.  It was a truly horrifying combat.  I love the dynamic lighting, and this would be something that would be really useful.
