This build mainly revolves around the end-game Kayle, so don't expect to be tearing throw your enemies just yet. Also note that THIS IS A HYBRID BUILD, I know many people make a fuss about hybrid builds and if you don't like hybrid builds then don't read. Also note that you will not be considered a "support," technically you are, but with this build treat it like a DPS. Your main goal is to get your turn around item (explained later) and to pick off squishies.

Runes:
I suggest you get magic penetration runes and also AP per level runes, just for an edge. Besides that there is not much to say, the only other rune I would recommend is mana regen, as you will be low a lot early game.

Masteries:
You can see them up top.

Items:
Generally when you're building items you want to get the AP items first. This is because it will greatly benefit your Righteous Fury. That's pretty much it.

Pros:

- Very strong endgame DPS
- Nice attack speed
- Ulti that helps you finish them off
- A great pusher/backdoorer

Cons:

- Bad early game DPS
- Moves somewhat slow early to mid game
- Needs a laning parter
- Squishy

Early Game
Early game you will want grab an amplifying tome for some quick early damage. Try to avoid any close contact with champions, you are very squishy and can be taken out easily. When you are farming try to turn on your righteous fury when your opponent gets close to you at all. The 400 range will be perfect for harassing and farming at the same time. Farm in your lane until you have enough gold for sorcerer shoes; these will give you the upper hand in lane fights.

Mid Game
Mid game should be around the same time you grab your blasting wand (or pickaxe) for your rage blade. Continue to farm until you have your rage blade, as it is one of your core items. Once you have obtained the rage blade you can commence team fighting. Remember your role is to take down and squishies and if presented a tank such as Mordekaiser, lower their shields. If you notice that anyone is attacking you AT ALL, pull back and lose the aggro, your health can drop fast. While in mid game pick up your first gunblade and try to get the sheen in the build for a trinity force.

Late Game
This is where you will shine. By now you should have your trinity force and you should be working towards your next gunblade (hopefully you will have a revolver). Be very agressive if with a partner and activate your righteous fury when fighting. If necessary get a heal on you so that you have the speed increase and slow them just so you get the chance to wail on them. Once your gunblade is complete you should grab a nashors tooth, this is merely used for its attack speed which makes it perfect for back-dooring (something you can do well alone). Finally always open a team fight with a slow on the squishy, that way if they pull back your team will pick them off easily, if you want to be safe USE THE ACTIVE ON YOUR GUNBLADE, IT NOT ONLY DOES DAMAGE, BUT IS A GREAT SLOW.

That concludes my DPS Kayle guide (My very first one BTW :D, leave a comment on your ideas of it please).
