i tested on again goblin pilferers. they hit me 47 as normal damage. and crits me 80! damage. i have 13,9 resilience.
my formula was simple = 100 - resilience > 100 - 13,9 = %86,1 of crit damage will be taken by me. 47 x 2 = 94 . 94 is normal crit damage a goblin pilferer would do on me. but because of my resilience they hit me 94 x 0,861 = 80 (rounded down) maybe misunderstood or i couldnt explain 71 damage mentioned above. 71 above post is the damage taken not the amount of damage reduced.
First of all in your formula it says (Crit hit of enemy - normal hit of enemy). this is equal to normal hit itself because crit hit = 2 x normal hit. No need of subtraction and no need to make a more complex formula. anyway. lets test your formula on my goblin pilferers:
damage reduction = 13,9/100 x (94-47) = 6,5
94 - 6,5 = 88!
but i get damage 80! as in my formula. so you are wrong bro.
