Kayle has been a favorite champion of mine since I started playing LOL. Luckly for me she was a free champ my first week and I quickly spent my first XP points unlocking her. She is a great laner, with the ability to help swing the outcome of team fights while unloading a ton of damage, and being able to debuff/cc her target.

Guide is not complete, but thought I would publish to see the reception it would get while I work on the body of the piece.

PROS
-Can make self or teammate immune to all damage with Intervention intervention.
- Righteous Fury makes her a ranged melee
-great Farmer
- Divine Blessing works for healing, chase, and escaping
- Reckoning is CC + damage + increase damage percentage
-Passive the Debuffs target

CONS
- Intervention does not stop CC's
-Mana Hungry
-Squishy
-typically targeted first

Marks
Greater Mark of Desolution - Armor Penetration, pretty much standard for any AD Carry to get those shots swings hitting home.

Greater Mark of Attack Speed - also viable, to help bump up that swing speed to near 2.

Seals
Greater Seal of Armor - Flat armor always good to keep early game sustain to allow you to farm your items.

Greater Seal of Attack Speed - SS is key for Kayle's Damage so if you think you wont be getting hit, then these boys will help your DPS.

Glyphs
Greater Glyph of Knowledge - Mana per level will help mitigate some of the mana issues Kayle has by mid game.

Greater Glyph of Scaling Magic Resist - MR at Endgame could very well see you live where you otherwise would be dead, Kayle can't do any damage or save a teammate while dead now can we.

Quintessences
Greater Quintessence of Cooldown Reduction - Helps us get that Cooldown to near 40, without only one additional item from build accompanied by Utility build.

Greater Quintessence of Health - Also viable to make you a little less squishy during early game.

As a carry, you need to farm. Kayle farms by using Righteous Fury, ergo level up your E first. As this build does not utilize AP, the additional damage for Reckoning does not truely outway the utility of higher heals, and higher movement speed buff of Divine Blessin. While your level 1 Reckoning gives the same CC of 35% movement speed reduction no matter what level. Duration of your Intervention is key so be sure to grab that at all available levels.

And what everyone is truelly worried about most. Your Build Guide. The listed build is designed to allow you to rip threw tanks and tower and enemy champions. With most games, over with one side at around 9k gold, your core build is [[Nashor's Tooth]. Everything else can and should be adjusted based off the enemy team. As such I will split my build into AS, AP, Balanced, and AD

Build 1 - AS Glass Cannon

Build 2 - MR Resist build

Build 3 - Balanced

Build 4 - AD Glass Cannon
