Question about sight/darkness (shooting)

[Don't kill me]

Straight to the question:

If I have pawn A standing in an artificial light (50%) and he is shooting at pawn B that is standing in darkness (0%), which one has the bonus to hit? This is assuming neither have dark vision. Mechanically, I would assume that pawn A has the bonus, but in reality it should actually be pawn B that has the advantage.

Speaking of dark vision:

The tool-tip says "no penalty to crafting speed", but says nothing about accuracy when shooting. Can I assume that dark vision also negates the penalty for shooting in, and/or out of darkness?

Apparently neither unless precept is involved?

If you have pawn selected and hover over another, you'll get chance to hit shown on screen.
Did that and got same hit chance regardless of lightness combinations.

For Dark Vision, it just erases all penalties related to "Being in Darkness", including shooting. It also gets rid of all bonuses for being in light. It basically seems to ignore all light-based bonuses or penalties, except those from the UV Sensitive genes or Night Owl trait.

For accuracy, I believe that Pawn A would not get the penalty to shooting at B. while B would get a penalty when shooting at A. Even if it is not a shooting penalty, there would be a movement penalty for the one in darkness and not the one in light.

Light is not factored in shooting except for darklight ideos. It used to be a thing to make bunkers where your pawns where under a roof in darkness being harder to hit where raiders in the sunlight were easier to hit. They got rid of that quite awhile back.

Yep, darkness has no effect on accuracy, unless you or the enemy has the fighting in darkness precept.

Keeping your killbox lit is actually making the game harder for yourself, because darkness causes a movement penalty, and you're helping the baddies move through the killbox/parimeter quicker.
