Thank you, you are legendThe numbers you see in Character window is the attack delay. It is the number of milliseconds counted between every two attacks.
Attack Delay = D / (1 + Total Attack Speed)
Where: D = weapon base attack delay in milliseconds (bow is 1000, dagger is 700, etc...)
So Erdi, you're equipped with upg bow (60%) and trans guarder (15%)
Total Attack Speed = 75% = 0.75
Attack Delay = 1000 / (1 + 0.75) = 571.43 = 571 (rounded down)
The Attack Delay will never reach 0 because, as we all know, rational functions of this form, 0 is an asymptote. You need infinite attack speed for it to be done.
