Hi, EkkoForLife here. Not trying to say I'm good at Kayn or anything, but I just wanted to share some knowledge on some of the games I played, and how the Darkin can be such a good tank/fighter for the team. For now, I do not know if he will get any changes, but so far, it seems like this build is working pretty good. Let's get right into it.

Ok, I gotta admit. Kayn looked cool in his reveal, his champion spotlight, and everything. Thats about the main reason I purchased the champion, and nothing else, expecting him to be a strong assassin (thats what I main). It turns out, his power as an assassin (in the assassin form) is OK, pretty decent in the current meta, and strong like any champion that just came out. BUTTTT! I figured he doesn't have too much of the snowball ability like the old Katarina (heh) or like the current Katarina (heh) and he is still very prone to hard cc, as his ultimate needs to damage the enemy before activating (unlike zed). Soooo.... what CAN he do? well, his Darkin form (the red one) gives quite good stats, passive, and tankiness. He heals a ton from his abilities, which can be amplified by Spirit Visage , and also Death's Dance. You can become this tanky fighter that heals up more than half of his health once he jumps into a team fight and land a massive Q. Holy **** I talk too much, gosh I guess this was what my mom was talking about when she threw that... anyways lets get started....

Pros
- Highly mobile tank
- High sustain
- High % health damage (anti-tank)
- Ult that gives you a free ride to any moment or dislocation ability!

Cons
- Prone to hard CC
- need to damage the enemy before ULT
- kinda meh in the early game (before Darkin)
- might have to wait 3 mins or so for the Darkin form (if ranged laner)

Pretty basic for a tank/fighter, scaling armor, magic pen to negate some damage while you heal up, some precision to deal more damage to tanks to heal up. I chose attack speed quints to make sure that you will have some better farming experience in the early game, but once you max W out, a simple W-Q will clear a wave easy, so its just for the early game.

Thunderlords will be easily dealt on the enemy champion, since with the W slow into a Q, will proc it. 0/18/12 seems more for the tanky fighter, yet if you want more damage, 12/18/0 wouldn't be bad as well.

Black Cleaver
- Great against tanky top laners
- phage movement speed
- CDR, and health

Death's Dance
- Sustain
- works great with abilities + passive
- CDR, and bleed effect

Spirit Visage
- item passive works great with Darkin passive
- MR, Health
- CDR

Why the W max? Well... In lane, W gives the best poke and damage. It's actually ridiculous how you chunk 1/3 of the enemy's health at lv3 with one spell. the scaling is awesome, and besides, once in the darken form, the knock-up will be superb!
Q max second will be obvious enough, damage, and dash, and E max last since it's an escape tool, and as long as you are the Darkin, you won't have to worry about dying to much :P

Farming..... at lv1 you auto attack and W sometimes to farm....
once you have some items and some skill points in W...


JUST W-Q


boom now u have farm

As the Darkin, you are the tanky initiator. A great way to engage in a team fight is to E through a unexpected wall, and pop out, Q, and land your W knock-up at as many enemies possible. you can stick around in the enemy team, dealing damage and healing yourself, until you are very low... then you ULT the tank of their team, and now you have your health back. E through some walls and gtfo.

To summarize, Your job is NOT to get extremely fed and destroy every ADC's dream. BUT to trust in your team, go in, knock-up, spin around, walk through walls like a boss, and hope for a better tomorrow. Thanks for reading!
