A small guide about combat mechanics of "Mazes of Karradash".
First: the values of ATK and DEF respectively affect the ability to hit and be hit.
As the PG attacks, the die roll that determines whether the shot was on target or not is based on the difference between the ATK (PG) value and DEF (enemy) value.
So, how important is to improve these values?
Consider this: the difference between the two values has a maximum excursion of 50 points (-25, +25). And even if our value ATK is much lower than the DEF of the enemy, we will always have a chance to hit him. Same things if the value of ATK is much higher than the DEF enemy: in any case he will have a (minimum) chance to dodge the blow.
So, if ATK(pg)-DEF(enemy)=30 or ATK(pg)-DEF(enemy)=50, you still have the same chance to hit the enemy.
Continue to increase the values of ATK (or decrease the DEF of the enemy) may not always be helpful: if your blows hit the enemy quite often, it may be unnecessary to spend rounds by increasing your ATK (or descreasing enemy's DEF).
