Yeah, I forgot about those weird situations where you have certain units that can’t hit other certain units - like planes and subs not being able to hit each other if no destroyer is with the planes.
In those situations, you have to do a little more figuring than usual. Still, even with rolling dice you still have to roll separately in those instances so it’s not that much different.
By the way, Low Luck can also be used for things like anti-aircraft rolls. Say you have 6 bombers attacking an IC. In regular dice, you would roll 6 dice trying to get ones. However in Low Luck, you can simply remove 1 bomber as an automatic hit.
The drawback here is that now the attacker still has 5 bombers to plaster your IC. If you rolled dice, you have a chance at getting anywhere from 0-6 hits.
