when i say luck, even though i used the expression of dice i in fact do not mean incorperating an rng.
Moreover I'm not talking about obscuring or keeping secret altogether the actual formulas that determine combat.
Rather I suggesting that we capitolize on the unknown element in the formula at every battle: "the enemy."
I think quintessentially I am suggesting that the player be able to make one to three on the spot decisions during battle that are hidden from the enemy and the result of each combat interval be determined by the various combinations that each player selects as well as his capabilities to preform those selections.
You really can make shit as complicated as you want by making combat develop through a series of sequences of stances/styles requireed to pull of a strang attack that might be countered or diverted if your opponent sees you doing them.
