What runes will give my auto attacks the most damage?
This is an important question to be able to answer before you start your item build in game. You first need to know what runes to select. For the purposes of this article, we will use two talons auto attacking each other at various levels and item values. Critical hits and attack speed will not be taken into account.
Applicable masteries: Sunder and Brut force.
Runes: Talon A will run with Armor Pen, Talon B will run with flat AD.
Talon A - Level 1 (Doran's Blade)
Attack Damage: 63 (Hits B for 63)
Armor: 15 (Effective vrs B: 9 or 8.3% reduction)
Armor Pen: 31
Talon B - Level 1 (Doran's Blade)
Attack Damage: 78 (Hits A for 71.52)
Armor: 15 (Effective vrs A: 0 or 0% reduction)
Armor Pen: 6
Advantage: Flat AD by 12%.
Now, where does that advantage switch? Not long after level 1, really. By the time they hit level 6, Talon A will have reversed the advantage completely. And He will maintain it until penetration items are purchased.
Now hitting eachother, that's great and all, but what about high armor targets later in the game? What armor point does Flat AD with a last whisperer overtake ArPen with a ghostblade?
Well, Talon A has 45 more armor pen than Talon B, once Talon A finishes his ghostblade, and Talon B has 40% more penetration than Talon A. Obviously 40% will eventually yield more penetration than 45.. and that point is approximately 115 armor. So, on all targets Higher than 115 armor, Flat AD has the advantage once again.
So, which one is better? I personally have both pages set up. At my Elo people pretty much always have more than 115 armor, so I find myself typically going for flat AD. But if their team is very squishy, I'll take out my ArPen runes and have fun.

Mathcraft: Armor Penetration or Flat AD runes?
5 comments:
very cool read, ive been looking for this. Thx for the analysis
however, i was just reading some more. and realized W Q and R scales off of bonus AD not total AD. So those 3 spells would gain little effect from the flat damage runes. I think in the end Armor pen is more viable. Sadly i spent a fortune purchasing a whole rune page of flat damages.
Flat AD runes are included in your Bonus AD, and therefore will increase your damage on QWR. The math will be very similar to the auto-attack math.
Very interesting. I alwasys thought pen outclassed damage.
It does, but only sometimes. The real advantage to getting Flat AD comes with the ability to purchase a last whisperer instead of a ghostblade.
In reality, you should have both pages set up for ranked, and if the other team is mostly squishy, take the ArPen. But against bruisers, where they're likely to have at least 115 armor, you'll do more damage with flatAD+LW than Arpen+brutalizer.
