Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is an extremely powerful ability power-based build that will make your enemies flee with fear at the sight of Kayle.
Start off with Reckoning and harrass your squishier enemy. Do not attempt to get the first blood unless your partner has a good damage output or high enough Health (such as Xin Zhao, Katarina, Akali or Nidalee) and is sure of his or her capabilities. Personally I prefer to stay behind, heal my lane partner and defend the turret. You will notice how quickly you'll start pushing your enemies towards their turret and keep them at low health after buying Fiendish Codex due to your deadly combination of Reckoning and Divine Blessing at around level 7.
Kayle's Ultimate - Intervention:
Many people use Kayle's ultimate in the most inappropriate situations, such as using it on an allied champion running away from a mob of enemies who clearly will take him out as soon as the skill's duration ends. Or in situations like team fights where a champion is being grabbed by the enemy's Amumu or Blitzcrank and Kayle's ultimate is being used to save that champion when he/she has low health.
-Kayle's ultimate should be used on an ally AS SOON AS THE FIGHT BEGINS! That way you assure your main DPS or Tank will not die and will be protected from any damage while the enemy is being killed by the rest of the team.
-Let's assume your team has clearly been defeated by the enemy and you're fleeing from them but unfortunately they spam stuns and slows at you and your team-mates. That's when you should Ulti and heal yourself, that way at least you survive while fleeing. Of course, you should always use your own brain and assess the battlefield, your fleeing routes and the state of your team.
The real damage will start showing up as soon as you get Nashor's Tooth and Berserker Greaves. The cooldown reduction, the attack speed and the ability power you receive from Nashor's Tooth makes it an ideal item for an offensive Kayle.
A bit later on, you will get yourself a Guinsoo's Rageblade which drastically increases you damage and attack speed in battle and will make you a turret killing machine - After getting this item it's usually GG. You should note, that if you're having trouble maintaining your lane, you should consider getting Guinsoo's Rageblade FIRST, and only after you have built it, continue building your Nashor's Tooth.
But if the game is still not finished, try getting that Zhonya's Ring. This shiny ring will give you a huge bonus to damage due to a massive amount of Ability Power summing to about 450 at this point of the game. The damage is so high that you will be hitting turrets for 350 damage at a lightning-fast speed and your Reckoning skill will be taking out HUGE chunks of the enemy's health. Not speaking of the massive damage you will be dealing with Righteous Fury.
-The active ability of Zhonya's Ring is a great addition to your existing ultimate, Intervention. Personally I use it in team fights where I'm the main target or in the enemy base, while taking down an Inhibitor and being attacked by the enemy, knowing that if I take their Inhibitor down at this point, it's going to assure my team a win.
The Runes in this build are the runes I use. You can use any runes you'd like to use...
