Is the -6 Blind Fire penalty added to environmental visibility modifiers, or does it override visibility? I've been going back and forth over this. On one hand, it seems to me that invisibility is pointless against a blind man.
Therefore, you really shouldn't add -6 Blind Fire to -6 Full Darkness/Thermal Smoke. Also, a -12 dice pool modifier is crazy hard. I realize that this is literally a shot in the dark, but I think it's excessive to make it a Long Shot test even for the most skilled marksmen.
On the other hand, it makes some sense for environmental conditions to complicate things. It's one thing if you're shooting at an invisible target in a brightly lit room, where you can clearly see obstacles and maybe even clues of the target's presence. It's another thing to try it in a place with shifting shadows or fog. So I could see adding -6 Blind Fire to -2 Partial Light, although the total penalty still seems overly harsh.
Is there a consensus on this?
