The guide might be old, but the way of calculating the damage has not changed. There is an updated version of this for lvl 50, but since the EU launch will start at lvl 45 this guide is hopefully gonna be helpful. Guide 1 is for the basic effects of defense, pierce etc, the 2nd guide is about the skillboard damage. http://forum.mmosite.com/thread/2/3...l_Pierce_and_Defence-52d3e681368689a13-1.html http://forum.mmosite.com/thread/2/3...d_Damage_Calculation-52ac26135c67f6813-1.html All credits to the creator.
