thanks for help. Could some one explain to me how using the black cleaver and armor penetration runes are inefficient together.

+75 Attack Damage Passive: Physical attacks reduce your target's Armor by 12 for 5 seconds, (maximum 5 stacks).

So does that mean if you hit an enemy 5 times you will take away 60 of their armor for 5 secs? Then if you had 35 armor penetration (via runes and masteries) their armor would be "their armor - (minus) 95)? How does it work?

Only reduction bring the armor to negative, but reduction is applied before penetration so,
if a target had 100 armor, and you have 30 armor pen, and black cleaver, then you drop them by: (100 - 60), then 40 - 30. Now if they had 70 armor: 70-60 = 10, 10 - 30 = 0 (Apen does not go below 0), so its a wasted 20.

oh I see thanks, im not quiet familair with what is the average ammount of armor you get when you reach lvl 18. What is a low armor and a high armor range for champions?

There for is armor penetration a waste for the twtich? and I should go with attackand or critical chance?

For my calculations with every rune critical chance it worked out to be 42.5% critical chance. Does the infinity edge plus ur chance by 20% or by 20% damage?
Therefor with the twtich there should be around a 50/50 chance that with each shoot it is critical from the very begining?

I could either get Armor pen and first real iteam get IE and leave out BC alltogethor, or get critical chance and then both BC and IE as both would work great with my runes?

Really want to know if my calculations are correct and if I will get +42.5% critical chance hitting from the very start of the game. So nearly every 2nd hit will be critical? And I can increase this by in game iteams?
And a critial hit is double your twtichs basic normal attack so 60 attack damage will become 120 attack?

Thanks.
