Okay so this is how actions/combat works
You pick a number 1-6. Then I roll a dice. Depending on the number I get and the number you picked, The following could happen.
Number picked is number rolled= Perfect Action
N+1 Overshot it
N+2 Really over shot it
N+3 Ver much over shot it.
It also works hte other way
N-1 undershot
N-2 really undershot it
N-3 Very much undershot it
The scale reduces to 1-4 when Doing Actions, but is 1-6 when attacking.
When defending, the Number varied is just the damage you save.
Perfect Roll = Perfect Protection
Roll +/- 1 = 1 damage taken
Roll +/- 2 = 2 damage taken
and so on.
