When i start play GE , i have difficulty to understand the relation ship between , ATK , DEF , PEN , IMMU , RES , ACC, Racial...and so on.. I don't know , so i don't appreciate about increase DEF , or RES .. until yesterday i spending 7-8 hours in Scarecrow experiment to understand how GE do the damage calculation. I not sure anyone have same problem like me . So i desire to share what i have experiment and what the result i got.. i can't 100% sure the accuracy , they are just base on my experiment, so can use for reference or any mistake is welcome to correct me.

I found that Magic attack will ignore Defend , and Melee and shooting attack will ignore RES. So RES is to resist the magic attack and , Defend is to defend the melee and shooting attack.

The basic calculation for Magic damage as below:

RES [include fire ,ice,lighting, metal] the number in percent . for RES 90 , it will scale down your attack by 90% which leave 10% damage..

Both scale factor maximum will scale down to 5%, no matter how , so the max for RES i think is 95 and for DEF no matter how large it will always leave 5% damage.

So to create the formula : Damage = [ (1-(RES/100)) x Base ATK]

* Base ATK is show in ATK in (alt + E)

For melee and shooting damage as below:

Melee and shooting they use AR to offset the Defend . and the Defend range in 0-190 range , each point decrease 0.005 [some weapon 0.00459, i dont exactly know why] , if the number wont greater then 0.95 if greater it will replace 0.95 instead of actual number.

For example you have 65 Attack Rating , and enemy defend is 200 , 0-65 Defend will cancel by your AR , after 65-200 it start decrease your damage.

To create formula for this : Damage = [ (1-((DEF - AR) x 0.005)) x Base ATK]

# If (DEF - AR) x 0.005 > then 0.95 , then Damage = [ (1-0.95) x Base ATK]

-------------------------------------------------------------------------------------------------------------------------------------------

Above have complete the basic Attack with defend or Resist. There is some scale factor , For Attack rating versus defend rating , Penetration versus immunity , Accuracy , Monster attack % ...and so on ,

For Attack rating versus Defend rating , by using AR - DR , the maximum value is +5 and minimum is -9 , if anything above then +5 it will only use +5 , anything below then -9 , it will only use as -9 .. Every Positive point is 10% additional damage , and any negative point is -10% damage..

Example : If Attacker have 65 AR , defender have 60 DR , so AR-DR = +5 .

The final damage to defender = Damage x 1.5 (which is 50% additional damage )

Example 2: If attacker have 55AR , Defender have 68 DR , So AR-DR = -13 and the minimum is -9 .

The final damage to defender = Damage x 0.1 (which is -90% in damage)

---------------------------------------------------------------------------------------------------------------------------------------------

Penetration versus Immunity

Penetration is work like gain , meaning it only add bonus to attack and it wont decrease the attack . When PEN <Immu it will always have same damage , when Pen> immu it will have additional damage , every point add 1% bonus damage.

So the calculation for final damage = Damage x [ 1+ (Pen - Immu) /100]

# Pen - Immu result must in positive value if negative place it as zero.

---------------------------------------------------------------------------------------------------------------------------------------------

For accuracy , I cant 100% sure for this but i guess it work as below.

Acc number should be in percentage.. the maximum value is 100% , which every time attack the damage is same . When ACC value is 70 , it will vary from 100% - 70% damage by randomly .. So like shooting and rubiana have poor Accuracy , improve her accuracy can make the damage more consistent.

-----------------------------------------------------------------------------------------------------------------------------------------------

When we add in ATK from Family attribute , There have ATK increment and Monster ATK increment , i found that ATK increment it will automatically calculate into base ATK , and Monster ATK is the additional bonus of Final damage .

Additional to Racial damage , such as Human , Undead , Lifeless , Demon , Wildlife. this Additional bonus attack apply in the enemy have same race , and the percentage is directly add in into final bonus

So to put everything together ,

For magic

damage = [ ((100 -RES)/100) x Base Attk] x [1+((PEN-IMMU)/100)] x [ 1 + (Rascial%/100)] x [( ACC random number)/100] x [ (AR-DR factor)] x [1+(Monster ATK %/100)]

For melee and shooting,

damage = [Base attack x (1- Defend factor)] x [ 1 + (MAX,0(PEN-IMMU)/100)]x [1+ (Rascial% / 100)]x [(ACC random number)/100]x [ (ARDR factor)]x [1+(Monster ATK %/100)]

-----------------------------------------------------------------------------------------------------------------------------------------

I think this is important , for some case example like KOA in recruitment quest , she have DR 77 , Imm 112 , DEF 288, RES 95

and from the calculation we know in order to make bonus attack from penetration , we need to have greater then 112 . if the total of penetration is far less then 112 , we can change our strategic to decrease her RES or DEF . for her RES 95 it will scale down the base attack to only 5% damage which is fatal.. If you have 1000 attack , she scale down to 5% which is 50 , even you have 10% bonus from penetration you only have 55 damage to her.. So if you can debuff her RES95 to RES 50 , then you gain back 50% damage which is 500 . which is more significant .

Hope everyone enjoy , and hope this help to clarify the parameter and give an ideal how it work.
