Question and power and penetration

#1Bennett2428Posted 4/16/2010 1:56:16 PM
So say I have an item that gives me AP but also gives me 30 magic penetration. If I use one of my AP moves on someone that only has 20 magic resistance, is there extra damage done due to the +10 penetration?

Armor Penetration and Magic Penetration work in an odd way. For example, let's say you get a Brutalizer. It penetrates that 15 armor. So 15 armor is ignored from your opponent. However, if you get a Last Whisper. It ignores 40% of their armor, so if they have 100 armor, you ignore 40 armor as opposed to Brutalizer ignoring only 15. Straight armor penetration is good early game.

Oh yeah, I never answered your question. Sorry for the double post. There is no added benefit after you reduce someone's armor or magic resist to 0.

more power leads to deeper penetration

ok, what you are looking for is armor/resist reduction
that's the only thing that goes below 0, but it's applied first, before % and flat penetration

Penetration can't drop a guy below 0.

However, reducing to 0 makes your spells hit like a train.

Penetration is applied in order

1. +X Penetration(the rest of the items/runes/masteries)
2. +% Penetration(Last Whisper/Void Staff)
3. Reductions(Black Cleaver/Stark's Fervor/Abyssal Scepter)

And the ONLY penetration that can go past 0 is the 3rd tier. This tier WILL do bonus damage past 0. But the 1st and 2nd tier will only reduce to 0.

Been confirmed by Riot Games admins.

I thought Reduction was applied before Percentage Penetration.

One of the Riot guys gave us an example with Black Cleaver and Last Whisper.

They specifically said that each hit of Black Cleaver makes Last Whisper more inefficient, which would only happen if Cleaver were applied before Whisper.
