This is a guide for a pure DPS Kayle, with the latest changes to her, the support side of her really got nerfed. However, with the buffs to her , she became a very powerfull AD carry that shreds armor and champions, and the most important part: minion waves. She now has one of the strongest farms in the game, together with fast movement she is a very deadly lane pusher.

I'm open for suggestions for this part, but the flat damage runes really help her early game.

Greater Mark of Attack Damage Damage to make last hitting and harassing very easy, with essentially a 1.4+ damage ratio on her auto attacks, she becomes a very deadly carry, even early game.

Greater Seal of Attack Speed Attack speed, helps last hitting, note that due to her new animations, this is already very easy, also gives you a stronger early game.

Greater Glyph of Cooldown Reduction To give you a 39.85 CDR with just Nashor's Tooth and masteries, enough to make her maintainable

Greater Quintessence of Attack Damage Same reasons as the marks.

Normal 9/0/21 for 9% CDR to make maintainable and for some nice magic penetration.

We start with a Dagger and a Health Potion to help last hitting, another option is starting with Boots of Speed and 3x Health Potion.

This helps you to get level 2 boots and a Long Sword on your first trip back.

The next item is Phage to boost our survivability and farming potential.

Next up is Zeal for some very welcome attack and movement speed, this helps kayle stay in range of her foes and deal more damage.

We take Sheen last since survivability and attack speed are more important than a double hit every few seconds, next up is for another 300g, this item compresses the other items into one and buffs their stats for only 300 gold.

Next is Stinger and Nashor's Tooth to allow us to maintain our Righteous Fury, and gives us a very nice amount of attack speed. The AP and Mana are a nice addition to keep our Q Reckoning usefull as a poke.

Our final core item is The Black Cleaver for some more damage, attack speed and some strong armor reduction that works well with your passive.

The final 2 items are situational, some pretty obvious choices are:

Banshee's Veil against balanced teams or teams with lots of AP.
Madred's Bloodrazor if the enemy team is building tanky.
The Bloodthirster gives you some nice damage.
Infinity Edge dmgdmgdmg.
Malady if you need a cheap but effective weapon and they are stacking MR.

Currently bugged but it will be 20% reduction once it is fixed. A decent passive together with Black Cleaver to melt away armor, note that the reduction benefits your entire team.

Use this to harrass and chase down enemy champions.

Your main heal speed boost, nerfed into oblivion, the speed boost can be usefull at times though. Dont use this unless you know the mana is worth it.

Your bread and butter skill, this is why AD Kayle shines:
Maintainable, costs almost no mana, and farms entire minion waves in a few hits.
Your target takes damage equal to 60 + 140% of your AD, while nearby units take 60 + 40% of your AD.

Now add Trinity, a huge attack speed, the armor reduction from Black cleaver and your passive. Yeah..

A strong ulti on a 36 sec cooldown. Makes you or any other team member invincible while you melt their team.

Is all you need.

is maxed before to give you a greater pressence in lane, allows you to keep up with any harrass the enemy throws at you together with Righteous Fury.

last but a point at level 4 since the speed boost is quite usefull.

Whenever you can as usual.

To help you chase down, escape and disable enemy champions.

Now the fun part.. Teleport gives kayle the ability to push any lane in a few seconds with her E and be very hard to gank due to her invincibility, speed boost and slow.

Other viable spells are
to get rid of any CC that gets trough your shield to be virtually ungankable.
to chase down, move faster, etc.
its flash!
