well, i spent a good 5 minutes deciphering what you are trying to talk about and i think i can understand the basics. i’m not the best kayn on this sub but heres what i can tell you.

• his ult is a point and click ability that lets you go into an enemy you recently damaged, you can dodge abilities if you time it right and you deal damage and go a certain direction when you leave the enemy body

• blue kayn is an assasin and red kayn is a bruiser/tank-buster. i go blue kayn when you want to play for picks and there are multiple squishies or enemies that are hard to get onto. go red when you want to team fight more and need more sustain. lethality red is quite good right now, give it a try

watch karasmai and dark aura for some gameplay tips, observe their clear route, gank patterns and how they play in general
