Yuuuu

ur dmg from second mace wont be reduced by 150 if u got 850, it doesnt work like that. The dmg reduction u will get its 30% just from ur second mace so actually a 300 magic dmg mace (+10 and great charmed) would be affected by 90 but thats only if u got +10 and great charmed and since u said u a free player i doubt u got the mace +10 great charmed so at the end u wont be losing 150 as u said it would be way less. Also the calculation u did with the fero stat and ur dmg doesnt work like that too fero works as a viseversa of resil stat ( if u have 50% fero and ur enemy got 50% resil both stat get neutral so u will hit as if u got 0 fero and ur enemy will receive dmg as if he doesnt have resil, basicly like if both are pve players)
