Magic Pen Reds, BLues, and Quints + 5 points in Precision will grant you 21+0.25*Level Magic Penetration or 25.5 Magic Penetration at level 18

item 3135 = +35% Magic Pen item 3151 = +15 Magic Pen item 3020 = +15 Magic Pen

So, if you were to forgo any AP/MR/CDR blues and if you were to forgo any AP or AS quints for Diana, you could have 55.5 + 35% Magic Pen at level 18

You could also do Piercing Thoughts mastery instead for 49.5 + 42% Magic Pen.

Can you explain to me what Flat magic pen is and what % is and what each one does and their difference's cuz am kinda stupid been tying to figure that out on google but they have to much BS

Let's say you have 30 Magic Penetration and 35% Magic Penetration and you deal magic damage to a target with 100 MR.

The 30 is the flat amount deducted from the target when applying your magic damage; so, their MR is first reduced from 100 to 70.

Before applying magic damage however, the remaining 70 MR is, again, reduced by your Magic Pen percentage (35% in this example). 35% is merely a 0.35 multiplier for those of you who may or may not understand percentages. So 70*.35=24.5. 24.5 is then removed from the remaining 70 MR when applying your magic damage since 24.5 IS 35% of 70.

So, let us assume you have 30 flat Penetration and 35% penetration and you do deal magic damage to a target with 100 MR. Your magic damage would ignore 30+24.5 of their MR since flat penetration is applied BEFORE percentage penetration.

I may have some mistake's here and there but keep in mind i only focus on Magic Penetration and Magic Resist Here Nothing else

Okay,

So to understand

Lets say am full build Diana ( am just gonna go with my normal build here and add to it some MP )

My Diana Build ( with magic pen Twist in it )

item 3020 15 magic pen item 3027 100 AP full stack item 3089 120 AP + 35% OVERALL item 3151 80 AP + 15% MAGIC PEN item 3135 80 AP + 35 MAGIC PEN item 3165 100 AP + 20% CDR

So overall i will have With the build ALONE ( No champion leveling no runes no masteries )

650AP 50% MAGIC PENETRATION 20%CDR 15 MAGIC PENETRATION

or if AD heavy team i go with this item 3157 and i remove this item 3151

which give's me

640AP 35% MAGIC PENETRATION 30%CDR 15 MAGIC PENETRATION

Soo

You have this build and then you have lets say a Maokai full tank build Am going full MR here just for the sake of this thread i don't even play Maokai

item 3111 25% MR item 3001 +60 MR item 3102 +70 MR + 1 SPELL SHIELD item 3065 +55% MR item 3060 +30MR item 3512 +55MR

So Maokai will technically have

+60 AP +30%CDR +290 MR +800HP +115 ARMOR

Soo

I take Diana's first build with full MP %50MP + 15MP with 650AP and the Maokai with 290MR + Lets say 3k HP + 60AP

And i i use just my Q which does 655AP +50% MP and 15MP how much Dmg will the Maokai take just from the Q and why?

Am trying to find a build here with runes and masteries and items that can peel heavy tanks

% or flat pen?

If %, it's easy, 7% from the mastery + 35% from Void Staff to about 42%

If Flat, it's about 55.53 I think (30 from items item 3151 / item 3020 , 6 from the Cunning Tree mastery at lvl 18, 6.03 from quints, 5.67 from blues, 7.83 from reds)

Then you have things like item 3001 which just amps all magic damage to people nearby by 10%, and item 3091 which reduces someone's MR by 25, and Kayle passive (3% per stack stacking 5 times for 15%) / Amumu passive (15 / 20 / 25 MR reduction from AAs)

Sure, let's take a 100 MR target for simplification, and for the majority of cases you'll have just void staff for %, so just know that Void Staff applies before magic penetration.

Flat Pen Example:

100 MR reduced by 35% from void staff is 65. (100 * .65 [this is (100 - %pen)/100]). Then their remaining 65 MR is reduced by your flat pen amount which is 55.53. In the end your MR is reduced to 9.47 MR.

% Pen Example (in this one it is tricky because the two % pens are different types so they don't stack additively and need to be calculated separate): 100 MR is first reduced by Void staff to 65 again. Then the remaining 65 is reduced by 7% which is 60.45 total remaining MR

Tips: % Penetration is best for against tanks, and Flat pen is best against squishies not building MR (Since flat pen works better with lower MR numbers than % pen)

Note: It is usually a good idea on a AP mage to get Void staff at some point, but it's just a matter of when to get it. If you have to deal with people building a lot of MR, Void staff is great.

Realistically, your flat pen will not be so high, as it is not recommendable to get Quint MR Pen, or Blue MR pen. AP Quints are better, and you usually want Magic Resitance Blues as well. And item 3151 is generally not a good buy on Diana.

uuuhhhhh..... item 3020 item 3135 item 3151 item 3001 I think that's the most you can BUILD. You can't really quantify it in % but let's suffice to say that once you have Sorc boots, void staff, and liandry's anyone without mr is taking true damage.
