We are all human and go crazy when it seems over a series of rolls we can only roll 4’s or a mix of 5 and 6.
Well if it makes you feel better I propose this rule.
Lets say you pick up 10 dice and rolling for INF to hit on a 1. Well, before you make your roll you can declare that the INF now hit on a 5. The odds did not change and it makes you feel better because you just know that today is the day you are just rolling 5’s.
You can do this for any attack value as long as every one knows what you are doing.
Armor attack on a 1-3, well you declare that your 6 rolls of 1-3 now hit only on odd results or even results or they hit on a 4-6 result….same odds of the attack.
Now of course when it comes to dice rolling what ever you say your “number” is you will most likely still be crestfallen when you still cannot hit crap. But at least this way you feel good that you can call your own shots.
