Kayle is a well-rounded champion. She is a hybrid of almost every role, giving you many play-style possibilities. Most people dismiss hybrid builds but Kayle benefits most from it (even after her new passive). This guide is for players who want to play Kayle as an AP/AD hybrid, while still supporting your team.

Update: I have now provided a build for support Kayle, which I recommend playing her as over a DPS Role.

Pros
+Has a slow, as well as a speed boost.
+Can efficiently clear minion waves.
+Can make herself or an ally invulnerable for a short while.
+Has a heal (also applies the short speed boost).
+Can be played several ways, depending what your team needs most.
+Decent area effect damage.
+can solo lane extremely well, as well as even going mid.

Cons
-Expensive Heal.
-Somewhat item dependent and is fairly ineffective early game.
-Does not do as much damage as pure dps champs.
-Is not a great tank if her ult is on cooldown.

Holy Ferver (passive)

Kayle's basic attacks against enemy champions reduces their armor and magic resistance by 3% for 5 seconds (stacks up to 5 times).

If you think Kayle is not supposed to be built hybrid read her ult. Attack speed greatly boosts the effectiveness of her damage. Once you're up around 1.5 you will see max stacks of this very quickly on your enemies. It is also beneficial to build AD/AP to maximize the full effect of her damage.

Reckoning

Blasts a target, dealing 60 / 110 / 160 / 210 / 260 (+100% of bonus attack damage) (+100% of ability power) magic damage and slowing its movement speed by 35% for 4 seconds.

While the target is slowed, Kayle inflicts 6/7/8/9/10% more damage to the target. Damage increase applies to summoner spells and items used by Kayle.

Kayle's opening move in any battle (unless an ally is in serious trouble). This move allows you to land attacks as well as giving you a big damage boost for a few seconds. Reckoning however is not spammable and should not be used unless you're actually going to engage or to escape.

Divine Blessing

Blesses a target allied champion, healing them for 45 / 85 / 125 / 165 / 205 (+35% of ability power) health and increasing their movement speed by 15 / 17 / 19 / 21 / 23% for 2.5 seconds.

This move used to give an obscene speed boost but now gives more speed for 2.5 seconds. Avoid taking damage because you could just heal up. Divine Blessing is also not spammable and should not be used regularly. Use it when needed on yourself or an ally.

Righteous Fury

Kayle harnesses her righteous fury to increase her attack range by 400 for 10 seconds. These attacks splash, dealing 20 / 30 / 40 / 50 / 60 additional magic damage to her target with nearby units taking 20 / 25 / 30 / 35 / 40% of her attack damage plus magic damage. This splash damage does not affect turrets.

Righteous Fury gives Kayle the best basic attack of any champion when activated. With this build it can be active 100% of the time. When active, Kayle can do area effect damage from ranged. This is Kayle's best move and allows her to harass, clear minions, and deal a lot of her hybrid damage.
Intervention

Kayle bathes a target ally champion (or herself) in a holy light, rendering them immune to all damage for 2 / 2.5 / 3 seconds.

Intervention is one of the moves you will always hear your opponents complain about. It can be used to temporarily make an ally or yourself immune to damage for a few seconds. This move needs to be used timely and needs to be used with precision. If you make yourself or an ally invulnerable too early it will wear off and your ally will die. It can be used to give you the edge in a 1v1 fight as well. If an ally is about to die you can combine this with Divine Blessing for an almost certain escape.

Flash

Many people will argue against using Flash as Kayle because of her speed boost and ultimate. It is reasonable to use Ghost but not as beneficial since Flash gives you a third option where as with Ghost you have two speed boosts, which isn't necessary.
Teleport

I typically grab Teleport because with the shorter duration of Kayle's speed boost it allows you to get where you need to be. As a support/off-tank/dps you will need to be ready to engage with your team. Kayle is also item-dependent and Teleport will allow you to go back more graciously to get those major upgrades.


Other viable spells
* Ignite can be useful if you see assassins or pesky get-aways happening.
* Exhaust is only viable against a heavy AD team. Otherwise you will have plenty of slowing capability with this build.
* Clairvoyance should be used if you're the primary support on your team.

As DPS Kayle you are pure hybrid. Even with her old passive gone, you still want to build both AD and AP plus attack speed. Since you need both of these stats put all of your points into offense. Get basically every damage increasing mastery you possibly can.

When playing Kayle as support go into the utility tree and take standard support masteries. Some of the points are your discretion such as how many you put into Swiftness and Awareness .

I've seen Kayle played many different ways; even as a jungler.

Early-game
I like to start off with my E, Righteous Fury. Any fight that may happen in the beginning will benefit from the constant damage this will provide in an early fight. It will also allow early minion clearing and will be your primary move to level up. Play fairly conservative in the early game. Kayle is item-based and until you get a few ranks in Righteous Fury you will not have great minion-clearing capabilities. If you find yourself using Divine Blessing too much play even more cautiously. It will cause you to run out of mana very quickly. Just focus on getting your CS up so you can become effective by mid-game.

Mid-game
By Mid-game you should be close to getting Guinsoo's Rageblade. I also like to add an early Vampiric Scepter for more sustainability. Once you get the bonus attack speed from Guinsoo's you will notice a drastic increase in your damage out-put. It is also viable to build either Malady or Nashor's Tooth instead; although late game you will need all three. At this point you will be able to easily clear your lane. You want to be in every team fight to turn the tides with your heavy area damage and your support spells. By mid-game you will be max-rank in Righteous Fury and can start getting Reckoning up. Some people will choose to put more points in Divine Blessing, which I would only advise if you're playing as your team's primary support.

Late-game
Finish building the three items I listed in the previous paragraph. You should have already sold the Doran's Ring to finish one of them. At this point Kayle will not have mana problems and Righteous Fury will be active 100% of the time you're in combat. As your fifth item build Hextech Gunblade. This is an essential item for any AD/AP hybrid build. For my final item I build Frozen Mallet. This adds a little more damage and will keep your enemies slowed from every attack; not just after Reckoning. Since most of late-game is determined by the positioning of fights, make sure you're always in the fray. Try to anticipate who will get focused down so you can use Intervention on them. Also make sure you use Reckoning on your team's main target to prevent their escape.

Start
* Doran's Ring-extra health and ability power help early on to make up for missing attack speed.
* Mercury's Treads- optimal boots for off-tank/support. Being in the utility tree will put you at 391 speed. If the enemy team does not have heavy crowd control I would grab Berserker's Greaves instead.

Core
* Guinsoo's Rageblade- pure hybrid item. It's attack speed effective greatly increases your damage out put from Righteous Fury.
* Malady-gives extra damage on every hit and provides attack speed and ability power. Its a much cheaper alternative than Madred's Bloodrazor.
* Nashor's Tooth- provides Kayle with cooldown reduction (to always have Righteous Fury up, as well as a lot of attack speed.
* Hextech Gunblade-essential item for any hybrid. Once this is built killing Kayle becomes fairly difficult.
* Frozen Mallet- allows your attacks to slow. Even after Reckoning wears off your enemies will still be slowed allowing easy kills. The extra health is always a nice finishing touch.

Other
Madred's Bloodrazor- many Kayle players build this item last. However, in most games you will never build this item. It's a great item don't get me wrong but there a cheaper alternatives.
Banshee's Veil- any good player knows when its time to build this item.
Black Cleaver- better in a more AD-based build but provides great damage and attack speed.

Manamune
Manamune is typically used in most Kayle builds. It is a fantastic item for AD spammers. Champions like Ezreal are great matches for it. Kayle however, is not. There is one spell you will be spamming as Kayle: Righteous Fury. This is a long-lasting spell with a relatively low mana cost. As I've said before you should not be using Reckoning or Divine Blessing frequently. Spamming these spells is characteristic of inexperienced players. Kayle is a serious candidate for ranked play after her revamp; but Manamune is not for her.


Support Builds
Itemizing as a support is a similar deal to tanking. You need to purchase items based on team compositions. While tanks typically build to fit the enemy team, you will be building to support your team in the best way possible. Sometimes you can also build against the opponent if its necessary. Your number one priority in games is warding (See Support Game-play for warding advice). Since the current meta prevents support from getting cs in the lane you will need to buy a couple gold-per-10 items. The best two are Philosopher's Stone (which you will build into Shurelya's Battlesong) and Heart of Gold (which you keep until your have 5 items, then sell it for space for wards). The items I listed in the build above for support are just a few support items. Your build like I said depends on the composition of the teams.

Here's a Kayle game I played the other day. I actually midded in this game which is completely possible because of Kayle's minion clearing capabilities.

It's a shame more people don't play Kayle. I feel like Riot is upset with that because she's basically the face of this game. She's a great champion and well worth playing after they revamped her. I hope you enjoyed my guide. Remember, this is how I play Kayle. If you have constructive criticism feel free to comment. Just don't be overly rude or negative. Thanks!
