(S13) Split 2 - Best Blue Kayn World Guide - 1223LP peak EUW split 1 (Challenger split 2).

Welcome! I am Dark Aura, the best Blue Kayn world. Reached Challenger 1223 LP season 13 (split 1) with only Blue Kayn. Also know as DarkAuraLOL from my Tiwtch stream. Make sure to check it out to get the most on how to play Blue Kayn. I am doing this guide to prove to people you can easily play and climb with only Blue Kayn, and that you don't need to be playing against ranged champions to play it, you can even play it against 4 tanks and carry. Hope my guide helps with everything you need to know about blue kayn :D Enjoy!

The darkin scythe (Passive) Kayn wields an ancient, sentient weapon that battles with him for control. Dealing damage against champions causes them to drops orbs that are automatically collected upon leaving combat, filling a bar above Kayn's portrait.

Once the bar is full, he can choose to either be overwhelmed by Rhaast or expel him to become the Shadow Assassin, based on whether he has damaged more melee or ranged champions, respectively. Once primed, the other option becomes available after 4 minutes. Kayn can continue collecting orbs for his other form to reduce the wait time.

The transformation can only be performed by interacting with Kayn's portrait while on the summoning platform, permanently changing his abilities.

Reaping slash (Q)
COST: 50 mana
COOLDOWN: 7 / 6.5 / 6 / 5.5 / 5
Kayn dashes forward, dealing 75 / 95 / 115 / 135 / 155 (+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 40 bonus damage against minions and monsters.

Blade's reach (W)
COST: 60 / 65 / 70 / 75 / 80 mana
COOLDOWN: 13 / 12 / 11 / 10 / 9
After a short delay in which he can't perform any other actions, Kayn performs an upwards sweep with his scythe, dealing 90 / 135 / 180 / 225 / 270 (+ 1.3 per bonus attack damage) physical damage to all enemies in a line and slowing them by 90%, decaying over 1.5 seconds.

Shadow step (E)
COST: 90 mana
COOLDOWN: 21 / 19 / 17 / 15 / 13
Kayn gains 40% bonus movement speed, is ghosted and can ignore terrain collision for 1.5 seconds. Immobilizing 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 7 / 7.5 / 8 / 8.5 / 9 seconds.

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

Umbral trespass (R)
RANGE: 550
COST: 100 mana
COOLDOWN: 120 / 100 / 80
Passive: Kayn's basic attacks and abilities mark enemy champions for a few seconds.

Active: Kayn can activate Umbral Trespass to infest a marked enemy champion for up to 2.5 seconds, revealing them and becoming untargetable for the duration. Reactivating Umbral Trespass ends the effect early.

Upon reactivation or at the end of the duration, Kayn wrenches free from their body in the cursor's direction, dealing 150 / 250 / 350 (+ 1.75 per bonus attack damage) physical damage to the target.
  • The Darkin Scythe is the (passive), that gives you Blue orbs upon hitting ranged enemy champions till you fill the bar, then you get your Blue form, or you just get it 4 minutes after getting Red form if you couldn't get Blue at first.

  • Try using an auto attack before using your Reaping Slash (Q) to cancel next auto attack time.

  • Always keep your Blade's Reach (W) until you can read enemy's movements, never use it at the beginning of a gank, they might be a free kill that you might miss, so just walk up to them, if they Flash, then you can react with Reaping Slash (Q), or just Flash to them, or even use Blade's Reach (W) to them on full range after they Flash, but if you instantly use Blade's Reach(W) they might Flash it and the delay on Blade's Reach (W)'s activation will make them escape you easily. Additionally, you can always use an auto attack before Blade's Reach (W) to make you cancel the next auto attack time.

  • Always use your Shadow Step (E) while farming jungle to heal up, also make sure you use it to reach camps faster, for faster clear. Another way of using Shadow Step (E) is by keep it up when invading enemy's camps or even fighting in the jungle to escape. Your Shadow Step (E) gets cut off if you get hit by an enemy champion auto attacks or spells, it gives you 1.5 seconds to force you out of the nearest position in the wall you are in, make sure you dodge enemy stuff and avoid it while inside a wall. Another thing, you can use your abilities in walls, and use Reaping Slash (Q) from wall to wall to make your mobility even longer. You can even hit camps with Reaping Slash (Q) and Blade's Reach (W) while in wall without getting your Shadow Step (E) stopped. Lastly, if you get hit in combat before using Shadow Step (E), you will need to wait 3 seconds before you can use it fully, else if you use it, it will only last 1.5 seconds.

  • Finally, your ultimate Umbral Trespass (R) is used in many ways, you can use it to deal more damage at any phase of the game, you can also use it to chase someone after a flash you predicted from him. Another usage for Umbral Trespass (R) is escaping, you can always use it to stay 3 seconds untargettable till your team reaches, or by waiting 3 seconds for your cooldown on Reaping Slash (Q) and Shadow Step (E) so you can escape to the nearest terrain or (Q) Reaping Slash to the other wall.
Summoner spells

FLASH: Flash is essential, and irreplaceable, for that whenever you have Flash up as Blue Kayn, you can permanently force team fight engages and Flash into 5 man with a fast AOE damage combo, which will legit solo win you the game. Also, it helps you at all points in the game more than any other summoner.
SMITE: As any other jungler would run, Smite is the choice, you want to make sure you run Gustwalker Hatchling which is the Blue Smite though, for that it's the best on Blue Kayn, for the mobility it gives you throuh bushes, helps assassinate, it is practical, where you can use it as a last resort to ult with Umbral Trespass (R), and you can use it to activate runes like, Dark Harvest.
Early game
Early game, your plan is, to go ward enemy raptors preferably, on the entrance around second 50 into the game, so you can know where enemy jungler is pathing. You always want to start your raptors, no matter which side, let's say you are topside raptors, you want to do raptors, into krugs, into red in that case, then look for a top gank "ONLY IF FREE GANK", otherwise path to bot/mid, if it's gankable go for it, then keep clearing botside, if not gankable, do blue buff and keep hovering laners, whenever you see an opportunity, go for it, if not just do a full clear from there. If you are botside raptors, you do raptors/red/krugs, into bot or mid gank, generally if you go for a gank, and die, you can always have a longsword or two advantage, which then if you go to your opposite side, even if you're getting invaded, you are stronger than them, and your early ward helps you to know if you got invaded or not, if you know that you did, just go to their blue afterwards, instead of wasting time going to your camps.
Mid game
Mid game you should have form and your one shot power spikes, you want to play for objectives, play for helping your team getting turrets by hovering them in the sidelanes, or invade if not risky, and if ahead. I would usually look for dives around my mid and toplaners while they're playing side, and get free turrets, then invade enemy jungle camps. You want to also keep your flash for important fights or shutdowns, play for AOE combos aswell.
Late game
Late game, simply wait for the right opportunities, do not just all in randomly, play around your team stuns, then use your combos, or wait for enemy to overstep, or stack, for a flash W Q combo. Prioritize the carries, ignore the tanks, play for closing up the game, not just for kills, play for baron, turrets etc.
The end
