I made this guide before Runnan being popular. In fact I was offended in almost every game. But now it's something normal, so people dont hate me THAT much ;D.
Now about penetration. We have 21% armor and MR penetration (passive + masteries). If We need more help comes from Wit's End. Im played a lot of games with my build, and I dont have one in which this isn't enough for me. Play few games like this (even without Wit's End).
And yeah, really good idea about this polsih being stuff :P. I hate playing with polish peoples too. Its sad for me :/

Eh, now many PLayes rushes Runnan on Kayle.
But well, imo either AD or AP. Penetration :P

And don't say you're from Poland. I bet you sahll get downvoted for this.,
I didn't voted btw.

With recent changes to runes you might want to have Atk. speed quints instead of marks and switch te AP quints for marks or glyphs. Also on your item sequence some of the images for the items aren't showing up you might want to check your coding and fix that up. If you want you can pm me that part of the code and I can fix it right up.

I played few games with your idea and you was right. I already change this in guide! Check it once more time and you won't be disappointed. Now about runes. Im was not very sure about this armor seals, especially after nerf, but you are right. Jungle is really easier with this instead of additional 72 HP. The same situation for glyphs. I was taking flat AP quints for better early (it helps a lot) but i can add your option for those who put on late. Big thanks for advices! :)

+ ... simply no, not in this HYBRID build. gives u better stats

is so useless... On any champion...
Just kick it out of this build and get instead. It gives you a lot more DMG, lifesteal, peeling ability and awesome active to chase/escape the enemies. Overall this build isn't bad BUT! it'd be better to switch your quints and glyphs. Glyphs of AS, seals=armor for better jungling (having armor seals is a MUST) Quints of ad/hybrid penetration instead of AP. It simply synergizes better with your on-hit build than pure AP runes.

Yup. With active "E" Kayle is defined as ranged champion. Additional bolts from Runaan's Hurricane applaying Feral Flare (Dmg and heal), her E benefits (like for main target), Wit's End and much more. Its allow to heal ~100 with every AA. Try this item by yourself. :)

Feral Flare on Kayle is good, but items like runaans suck balls. Is kayle even defined as a ranged champion?
