Steht imo irgendwo in der Help Datei:

Code: 
Damage of attack normally: 

Damage (HP decrease value)(attack power ÷= 2 of A)-(defense power ÷4 of B) 

·Actual damage changes at random within the range of 80-120% of the above-mentioned value. ·Three values are multiplied for "Kill without fail" and "Critical Hit". 

·Hit rate of attack is usually (%) =100-hit rate -(rate (%) of hit of equipment arms of 100-A)×+ (quickness -1 of quickness ÷ A of B)1÷2 

·When the option of "Ignore Monster Evasion" is given to arms, the basic hit rate becomes a hit rate as it is. ·Hit rate change value (%) is multiplied by present "Condition". 

·When B is equipped with the protector of "Rise Avoid of Physical Attack", 25% is subtracted from the hit rate. The hit rate is unconditionally assumed to be 100% when under the "Condition" that B cannot act.
Eignet sich übrigens sehr gut... Benutze auch diese Formel in meinem AKS und für DMG is die sehr gut...
