At risk of being self serving, I would like to put forward that the Umbral Darkvision trait, as per 



be appended to apply to Shadow tiles. 

It feels like an oversight that it doesn't.

I think darktiles work a bit awkward to begin with.

Correct me if I am wrong but, currently it works like:
"Standing inside the dark tile reduces your hit." Right?

This is awkward though, cause people shooting into the dark (I guess smoke too) do not lose any hit.

Wouldn't it be better if it worked like:
"While standing inside dark tiles, on being attacked reduce attackers hit."

Kinda would make it different from light/bright tiles that way too.

edit: And yes I know it also grants evade.
