Greetings!

My name is Alacroy, I've been playing League of Legends since it came out, and have been ranked High Elo more than once, I am currently unranked, (I don't really play Ranked anymore), but I am still up to date on how champions work, and all that other stuff.

This is my first mobafire guide, please comment how you think I did and what I can improve on!

Much love,
-Alacroy. <3

Kayn's Passive

"Kayn hones his shadow skills by hunting ranged opponents, while Rhaast fuels his bloodlust by going toe-to-toe with melee champions"

Early on, this is how you're going to get your form, you'll get your form around level 8-10 unless you gank a lot and get it at 5-6.

As the passive says, you will want to fight ranged champions to become Shadow Assasin first, you'll probably want to gank bot, and top if there is a ranged champion top.

You will want to fight melee champions if you want to get Darkin form first, you'll probably want to focus on top as more than likely, there will be a melee champion there.

Kayn's Q

"Kayn dashes forward, dealing 55 / 75 / 95 / 115 / 135 (+ 0.65 per bonus attack damage) physical damage to all enemies he passes through before flourishing his scythe, dealing the same damage again to surrounding enemies.

Both instances of Reaping Slash deal 55 bonus damage against monsters."

This is your bread and butter, the ability that you are going to spam harder than anything else, you will use this as a gap closer, and this ability is essential to Kayn jungling due to the extra 55 bonus damage against monsters.

To use this ability to its full capacity, you'll want to get up and close as possible to the enemy champion, and Q through them to deal extra damage, and then your AoE will hit them as well.

You can also use this ability to go through thin enough walls, especially useful for if your E isn't up.
Kayn's W

"After a short delay in which he can't perform any other actions, Kayn performs an upwards sweep with his scythe, dealing 80 / 125 / 170 / 215 / 260 (+ 1.2 per bonus attack damage) physical damage to all enemies in a line and slowing them by 60%, decaying over 1.5 seconds."

This ability is AMAZING, it helps overall in the jungle, and especially when ganking, it is what makes your ganks so deadly.

You'll want to use this right after you Q to slow them, to help finish them off or slow them for your team mates, this is especially useful in team fights.

While please note that in Darkin Form, this knocks enemies up, and is probably the best thing about Darkin Form, you're able to knock up more than one target, for a good amount of time, and Q them straight after dealing a large amount of damage.

Darkin Form W is especially useful in team fights, as you can knock up the whole enemy team, or the enemy carries and single them out.
Kayn's E

"Kayn gains 40% bonus movement speed, is ghosted and can ignore terrain collision for 1.5 seconds. Immobilising effects will interrupt Shadow Step.

Kayn heals himself by 100 / 115 / 130 / 145 / 160 (+ 0.4 per bonus attack damage) upon moving through terrain for the first time and, if he's not in combat with enemy champions, Shadow Step's duration is increased to 5 seconds.

Entering combat with a champion after the effect is enhanced reduces the remaining duration to 1.5 seconds."

This ability is probably what makes Kayn's ganks possible, and his jungling clear so easy, you're able to heal through a wall right before a gank, and gain massive amounts of movement speed to get there, not to mention in Shadow Assassin form, the effect lasts longer.

Another thing, that all Kayn's should know, is that you also gain the movement speed even if you don't go in a wall. You should use it how Draven would use his W, you'll see Dravens using their W to dodge skill shots, or get out of an AoE, you should use it for the same effect to dodge something like a Jax E or an Aatrox E
Kayn's R

This ability is your ultimate, an important ability for both forms, and both lanes.

You will want to use this to dodge skill shots, or CC such as Orianna's R. This ability can dodge basically everything, not to mention let you TP with someone.

In Darkin Form, your R will heal you for an insane amount, turning a fight over, especially if you build right.

You may also use this to steal Baron, simply because you may not use any summoner spells while you're in your R, BUT smite, meaning you can steal Baron or Dragon while in R form and get away with your E or Q.

Mobility Boots

Some people are probably wondering why I put Mobility Boots in all of the build paths possible, and here's the reason why. Mobility Boots is the best choice for Kayn, Kayn relies on ganking early to get ahead and to get his form, not to mention it helps not just you, but your team.

Youmuu's Ghostblade

Youmuu's Ghostblade is a great item for Kayn as it fits in with his mobility and lethality, the two stats that make him deadly. This item is an overall good idea to have after Duskblade because it helps with ganks via mobility and damage to get yourself ahead and your teammates.

Guardian Angel

Guardian's Angel is a great item simply because it makes you that much more annoying, and sometimes you'll need it, Kayn is one of those champions that hardly ever die, much like Tryndamere, you can simply use your E and get out, but sometimes, you'll eventually die, and it's good to have Guardian Angel, in case your E comes up afterwards and have a better chance of getting away.

Dead Man's Plate

Dead Man's Plate is a great defensive item on Kayn, especially when you're in Shadow Assassin form, as you're extremely squishy and die fast, it offers a good amount of defensive stats, 60 armor and 425 health, and of course, it wouldn't be a Kayn item if it didn't give you some type of mobility.

Dead Man's plate not only helps you defensively and live longer, it gives you movement over time, fitting right into Kayn's kit.

Edge of Night

Edge of Night is a great item for Kayn because it helps you offensively and defensively, while in combat, it gives you a spell shield, something that can save your life tremendously, and is something you should seriously consider adding into your build.

Maw of Malmortius

Probably the most self-explanatory item you should build, Maw is a great item against AP or if you're behind against AP, it gives you good damage and it makes you harder to kill when you get a certain amount of hp.

Lord Dominik's Regards

LDR or Lord Dominik's Regard is one of the best tank shredders in the game, especially when it's bought with Black Cleaver, while this item is great for going against tanks, it's only really needed when there are multiple tanks, not just one, Black Cleaver is best for a single tank.

+

You'll always want to take Flash + Smite simply because Smite is essential for jungling, while Flash is just a good idea to take because you have an unlimited amount of options to use it for.

These are the skills you should use to engage in certain forms

I've seen a large amount of Kayn's not know where to start, and it's pretty simple, and surprising (IMO).

You start Raptors, while most people will be confused, with Kayn's Q, it's quite easy to take Raptors, you'll simply want to auto attack the large raptor, and Q the baby raptors, you'll want to run away and wait for your Q, then Q back onto the baby raptors, finish off the last one or two, and auto attack the mother raptor a few times, and it should be dead.

You don't have to use smite for this, but you may if you want.

The most important part on Kayn is ganking, you have the best ability to gank, your E, you can go through walls to easily land your Q + W, finishing targets off, and getting your form early.

Your passive relies on you ganking, and it's essential for Kayn to get his form early to wreck, you'll want to gank bot a lot, trying to go behind the enemies through walls to catch them off guard, the only times you wouldn't want to gank their bot, is if they have a Vayne or Alistar, these two will dumpster you, and push you away, making it impossible for them to be ganked, unless they're really pushed up.

Ganking also helps your team (duh) and gets you far ahead, you'll probably want to take Raptors, then Red, then Wolves then blue, then Scuttle and see if you can gank mid or top, this is an essential way (IMO) to get a free early kill.

Here are a few tips and tricks through text.

When jungling as Kayn you want to use your E to heal from your wall, this is a basic tip that some Kayn's just don't do.

A trick you can use is your R to dodge things like Orianna's ult, Sion's ult, Blitzcrank Q, basically anything honestly.

In a 1v1 situation, if you're low and the enemy is low, but you can't directly kill him, you can Flash + W (at the same time) for a very surprising instant W (I only suggest doing this if you're in Darkin since the knock up), to knock them up, then Q and R them, or just simply Q, and kill them.

A lot of Draven's use their W to avoid skill shots, you want to use your E to do the same, your E gives you a good amount of movement speed, and you can use it to dodge things like a skill shot, or get out of range of Jax's stun. This ability is NOT just for walls.

I will update more tips and tricks I find playing Kayn, but since he is a new champion, these are all I can think of, for basic tricks.
