### Season 3 Jungle - Armor Pen

Senior Member

Just did a quick calculation to see how much armor pen a jungler like Nocturne would need for the new jungle, but I want to make sure I'm right!

Relevant Info:
Armor Pen Calculation: Armor Reduced = Target Armor * (1- Percent Pen) - Flat Pen

Masteries:
8% Armor Pen Mastery
+5 Armor Pen Mastery

Mob:
Lizard Elder 20 armor
Blue Golem: 20 armor

The following equation should give us the needed flat armor pen to bring a target with 20 armor (buff mobs) down to 0:

0 = 20 * (1-.08) - (5 + Flat Pen)

Flat Pen = 13.4

Is this right? I have a bad habit of mixing things up, so I need a double check!

I can't say if you're right, but I can tell you that with the changes, armor penetration has been cut in half, to 12, from 25, considering you run marks and quients. Either way, you won't have enough, so it's probably smarter just to spec them in damage instead, which will help your ganks and scaling on your abilities as well.

With the new Hunter's Machete true damage, Attack Speed is still far better.

You sir are correct! Don't listen to those other guys, armor pen is far better than attack speed on Noc in S3. Source if you want to check your work: http://leagueoflegends.wikia.com/wiki/Armor_penetration (http://leagueoflegends.wikia.com/wiki/Armor_penetration)
