It's called a Battle System, here is mine

if AC-AP=0 |Damage Taken= Normal Value
if AC-AP<0 |Damake Taken= Normal Value*(1+(|AC-AP|/10))


erm, I hope u guys understand this.
Im breaking it down into steps so im sure u will get it clearly.

1) first subtract the AP(Attack Power) from the AC(Armor Class) (Example (AP=14 AC=8))

8(AC)-14(AP)= -6

2) Then, find the abs of the number you got out of the first step.

|-6| = 6

3) Now, divide this number by 10

6/10= .6

4) add this number to 1

.6 + 1 = 1.6

5) Now, take this number and multiply it by the ap

14 * 1.6 = 22.4

6) Round, and you have your result!

Hopefully with this formula i developed someone with a low AC that is struck by an Attack with High AP will take more damage.
If someone with a high AC is struck by a low AP they will not take as much damage. Every attack deals at least 1 damage. HP cannot be healed from a very high AC.

-Note: The modifiers only applie to PHYSICAL damage, as from a sword or bow. Elemental damage follows different rules.

Its simple really, every point of resistance someone has lowers the damage they take from any form of that element by 5%.

I have a fire resistance of 2. I am then struck by an attack that deals 10 fire damage. I only take 9. Easy, huh?
