LOW LUCK DICE:
WHAT: Low Luck dice (LL) are an alternative to regular dice. Essentially you add up all of the "points" from the units you're attacking or defending with, divide that number by six, and that's how many guaranteed hits you get. Then, whatever's left over, you roll for.
WHY: LL dice essentially remove most of the luck from battles, and they allow you to calculate exactly what you need to bring into combat to win. So which is better? That all depends on each player's preference.
HOW: For example: Let's say you're attacking with five (5) tanks and two (2) infantry against one (1) fighter and four (4) infantry.
You start by adding together all of the attacker's "points".
Tanks attack at 3. Infantry attack at 1. So the attacker has: (5x3) + (2x1) = 17 points
If you divide 17 by 6, you get 2, with a remainder of 5. So the attacker gets two (2) automatic hits, and rolls to try to get a third hit. Since the remainder was 5, he needs to roll anything but a six to score that extra hit. So the attacker has 2 guaranteed hits, and can possibly get 3. With regular dice he could have gotten as many as 7 hits and as few as none.
Now the defender rolls. Fighters defend at 4. Infantry defend at 2. The defender gets: (1x4) + (4x2) = 12 points
Divide 12 by 6 and you get exactly 2. This means the defender gets exactly 2 hits. There's no need to roll.
Both sides remove casualties, and you're ready for round two of combat in the same manner.
Special cases are detailed below:
1. Battleship Bombardment: Low luck is used; battleships fire in their own phase and only land units can be taken as casualties. ex: 4 battleships bombard (power of 16); two automatic hits and roll a die that hits on a 4 or less for the third.
2. Sub First Strike: Low luck is used; subs fire in their own phase and only sea units can be taken as casualties.
3. AA guns: Low luck is used for overland flight and battle:
3a. Overland Flight: For each 6 aircraft flying over an AA gun from one location, one auto hit is dealt. If there are both fighters and bombers, the hit is randomly dealt to one of them. A die is rolled to determine final hit for numbers not divisible by 6, as normal. Aircraft flying over AA guns originating from separate locations are rolled for separately.
3b. In Combat: For each 6 aircraft participating in combat, one auto hit is dealt. If there are both fighters and bombers, the hit is randomly dealt to one of them. A die is rolled to determine final hit for numbers not divisible by 6, as normal.
4. Weapons Development: Low Luck is not used. In other words 6 dice will not give you an automatic technological improvement.
