I know that there's a topic about penetration and the effects of it against an enemy, however I was wondering how penetration is calculated. (i.e: the additional penetrating rate) I was comparing my penetration with 2 other sins.
I also realized, even without wearing gears, my alt still has 9.90%. rip
So I'm wondering, what factors into penetration? (Sorry if this is a silly question...but I'm a noob when it comes to stats ><)
