Hello my fellow Kayle mains, my name is Dpecivo and welcome to my guide!This is my first guide so it will be short, but i will cover all the important things you should know as a Kayle player.
First of all, why should you play Kayle? She is a literally 1v9 champ monster after the 30 minute mark. She can easily carry games, but do not be misunderstood, she is not that easy to play, that's why you will need this guide!
She is a safe champ to pick also with heals/ms buffs, with her ult Divine Judgment and her insane damage input she can fit in almost every team comp.

PROS

+Crazy scaling into late game
+Good teamfighting potential
+Good poke and sustain in lane

CONS

-Squishy
-Depends on good positioning
-Weak early
-Depends on teammates not to int early on so you can scale

EARLY GAME

You always start with Starfire Spellblade, keep last hitin until lvl 6. After that
you can start real poking. Go for Radiant Blast for slow and damage, then follow up with quick aa then Starfire Spellblade to prock Press the Attack, you will take third of his hp. You can do that 2-3 times than all in with your Divine Judgment. Do not forget to use movement speed buff from your Celestial Blessing to catch on or dodge skills. You should always freez and build slow pushes, when wave colapses on there tower do NOT STAY IN LANE! Go for deep wards of crab, even recall.

MID GAME

At this point u have your Kraken Slayer and Nashor's Tooth. You keep slow pushing and then star looking for skirmishes, fight for drake, be confident in your damage but do not forget your squishy so positioning is everything! Keep split pushing when your Teleport is up, but do not overextend. If your Teleport isn't up go mid with your team. If your team happens to feed botlane ask them to switch lanes, play safe, farm, and don't worry to much, you will outscaled them all!

LATE GAME

This is when you are lvl 16 and have 3 items, now you are goddess of the rift! If your team is ahead look for fights, contest drakes and baron. Always spilt push if your Teleport is up(split push at the opposite side of objective you want to take!) Stay behind in teamfights, kite them, use ult to save your damage dealers if you do not have them do not be afraid of using in only on yourself.

So that's all for now guys, there is alot of thing left to say but we will leave it for next time! This is my first guide and English is not my mother language but i hope this was helpful for all you Kayle mains and casual Kayle players, Do not forget to vote if you like it and comment if you have any questions and maybe want a deeper guide on How to Kayle!

Until next time, stay safe and good luck on the rift!
