Hello, and welcome to my first guide!

I've been playing Kayle for a while now, and I haven't ever really done poorly with her. She's such a fantastic multirole champion. This guide will cover basic builds and strategy around some of Kayle's potential roles.

I will say now that this guide is going to be a bit bland and somewhat incomplete for a while. More stuff like videos and fancy pictures are going to be added later for some flair. Otherwise, the guide is perfectly usable.

APAD (Ability Power/Attack Damage Hybrid) carry is a versatile build, working in Solo top, Solo mid, Twin top and dishing out huge levels of damage in team-fights. Tank Killer takes advantage of Kayle's passive and attack speed allowing you to melt enemy tanks within seconds, especially if Teemo is in the game with you. Support Kayle focuses on supporting team mates, and keeping everyone alive, including yourself. This gives Kayle the potential for damage (Her Righteous Fury does tons during a team-fight.) and gives her lots of beefiness and survivability so she can get in the middle of the action to save someone without really putting herself at risk. Survivalist is a specialized build that gives her a balance of tankiness and damage output while sacrificing a bit of both.

PROS

Most flexible champion
Huge damage output

Intervention is one of the more valuable ultimates
Can use pretty much any item build and do well
Cheap

CONS

A bit squishy
Can be slow to build unless carrying
Often focused

Kayle's early game is kind of weak, but is easily fixable with runes.
The rune sets look a little odd. I know. But trust me on this. I take 9 Greater Glyph of Scaling Ability Power for a bunch of scaling AP. These give you almost 27 AP at level 18. This is surprisingly valuable early game because the less Kayle has to rtb, the better. Greater Quintessence of Ability Power Helps a lot with that early game AP, helping you to dish out way more damage. Greater Quintessence of Precision, Greater Quintessence of Attack Damage were also taken for the same reason. Greater Seal of Vitality, Greater Seal of Armor and Greater Seal of Magic Resist were used to ease off some of the damage Kayle is prone to taking early game. Greater Mark of Desolation and Greater Mark of Magic Penetration were taken to enhance her early game damage further. Greater Mark of Scaling Attack Damage only adds seven attack damage at 18,but is still valuable as Kayle only needs a little attack damage to get a lot done.

My masteries are pretty simple. Adds a bunch of AP, AD, and Armor and MR early game to further enhance the runes. That Archmage mastery is going to become your best friend.

For items I start off getting a Doran's Ring because it gives you more early game health, plus AP and mana regen. Next I go home and get some Boots on. Then I-

WOAH WOAH WOAH WOAH.

Nashor's Tooth? Are you KIDDING me?
No. I am not.
Nashor's Tooth is a fantastic early game item on Kayle. It provides mana regen, AP, attack speed and cooldown reduction. All of which benefit Kayle immensely. As to why I go with it versus Guinsoo's Rageblade early game, is because it's simply easier and faster to build into early.

After getting the Rageblade I begin to build into a Hextech Gunblade. I start off with getting the Hextech Revolver. The spell vamp works with Kayle's Righteous Fury and well as life steal. As such, after the revolver I go for the Vampiric Scepter. By this point, I should be slapping hard, and won't take long to finish off the Gunblade.
After that, I stick around and start making people very mad with all of my damage.

By this point, you're dishing out loads of damage, and they're going to start focusing you.
So, what now?
Rylai's Crystal Scepter.
Getting focused?
They should all be dead by now.
The game is coming to a close now, and you need a way to finish them off.
Hmm. Kayle could use a hat, don'tcha think? Yeah, a hat might be nice. Go back and grab a Needlessly Large Rod, go score some kills (Skill is trivial at this point),recall and get your Rabadon's Deathcap.

Congratulations! You are now the single most dangerous thing on the battlefield.

Skill sequence isn't super important on Kayle. Focus on your Righteous Fury primarily, with Divine Blessing prioritized next. Your Reckoning will only be truly useful for it's slow until late game, so prioritize it last. As usual, get your ultimate Intervention whenever it becomes availible. As for your rotation?

Q>E>Wait until they're dead
or
Q>E>Ohgodithurts>W>Okay, now they're dead
or
Q>E>GANKED>R>nopenopenopenopenope>B
or
E>tank's dying>W>you're dying>R>Q>win

Yyyeah, not super important either.

Okay, now this is important.
Go with Ignite and Flash, because you don't have an escape ability, and is one of your weak points. In certain cases, you might want Surge, particularly if you've got a Sion on the enemy team. Why? After he stuns you, you're going to need to make up for lost damage. Surge will do this with gusto.

Welcome to the single most effective farmer in the game.

I mean that. Your Righteous Fury clears waves like you've never seen. With such a low mana cost and low effective cooldown, you can sit in a lane and push pretty much forever.

...

That's it. It's crazy easy.

Yes, Kayle is a fantastic jungler.
No, this is not a jungle build.
But you can do it anyway.
Because Kayle.

Kayle is a serious asset to a team. Fortunately, being a team player is easy too.
If you have a lane partner, be sure to have enough mana to slow opponents with Reckoning and save their *** with Divine Blessing and Intervention.
In teamfights, what you need to focus on is your tank. I would advise saving Intervention for the last second, you can use it when your tank initiates if they are about to blow every cooldown they have on it. This will make the enemy team very mad.

Kayle can do anything.

Solo Top

When going solo top, the biggest thing about that is mana management.
If you have a jungler, ask if you can borrow blue.
If you can't get blue buff, only use your E during the lane and conserve as much mana for heals as possible.

Harassing

This is fairly easy. Your Reckoning is a high damage, long range ability with a slow. While it is a very good harassment tool, I would advise against using it unless you have some mana potions, or blue buff. In any other case, use your E's splash damage to hurt your lane opponent without putting yourself in too much danger. This does, however, push the wave, as you are hitting minions to get that splash damage on the opponent, so be careful with that.

Solo Mid

Pretty much the same rules apply. I would advise getting either mana pots on your first return trip or have someone leash blue for you. The Crest of the Ancient Golem is crazy useful.
I would also advise going for a Hextech Revolver before Guinsoo's Rageblade when mid.

Duo Lane Top

If you're going duo top, you're going to need to support your lane partner just a bit. See the Teamwork tab above.

Solo Bot

Okay, so you got the short straw this time. Either someone has left or you have two junglers (HURR).

Rule #1: Play it safe

Okay, so solo bot lane is rough. You're likely going to find the AP carry and a tank down there. Get Doran's Ring, then a Hextech Revolver. Then go look at the Tank Killer page for the rest of your build. You're going to get pushed around a lot down there, so be ready for it. I would also advise purchasing a Sight Ward or two.

Rule #2: Don't solo bot

I know this is Kayle we're talking about here, but solo bot is a very, very dangerous lane and you risk hurting your gold income too much, because you will not get many chances to farm. If you ARE forced to solo bot, build Tank Killer and fear no man. Because they'll be too busy exploding from Righteous Fury to be much of a threat.

So why use tank killer if you go Solo bot?
Because the tank who is likely in bottom lane is going to get a good bit of farm, so you'll need the right stuff to take his beefy *** down.
