Hey, thanks for the feedback.
* The Darkness Lingers seems really expensive at 3CP. For 1CP, you could reroll the 4+ instead and have a really solid chance of keeping night going anyway. 3CP is the cost of Orbital Bombardment and Agents of Vect . Maybe I"m under-valuing it, but 3CP feels like too much to me.
I agree that 3 is too much,especially with the command reroll available. 2 is probably the sweet spot. 1 would be a no-brainer.
*In Midnight Clad probably doesn't need to have a random roll for its Night rule. Just flatly reducing the range of weapons that wish to target the unit by 6" seems reasonable. Kind of like the old rules for Night Shields on dark eldar vehicles.
Also, you should clarify whether or not the range penalty retroactively impacts the first unit to target the unit (thus allowing the stratagem to be used.) If you're 35" away, and I target you with a 36" gun and THEN you pop the stratagem, is my attack wasted? Do I get to target another unit?
I'd be fine with a static 6", it's only affecting 1 unit after all.
I would tend to allow the shooting player pick a new target if the original is out of range. I don't think robbing players of agency in this manner is good for the game.
