So, if one unit has attack 5, and another has defense 10, does it mean the following:
Attacker makes a roll 0 to 5 (or is it 1-5 ?)
Defender makes a roll 0 to 10 (or is it 1-10?)
Then defender value is subtracted from attacker value. If it is 0 or less, then it is a miss. If it is positive number, then it is a hit with the damage of that number.
Is it how it works?
Also at what point attack/defense benefits are accounted and how? There are 2 of them, one is on strategic map, another is on tactical map. Do they add together (additive percentage) or multiply (commutative percentage). Basically, if there is 25% defense bonus on strategic map and 25% defense bonus on tactical map, will it give you 50% ( = 25+25) or 56% ( = (1.25*1.25-1)*100% ) of defense increase?
