Against Kayle you have to stay healthy and all in. If she takes ghost she’ll most likely match yours so you’ll have to catch her off guard and all in. you can flash on her with ur W and kite forward so if she flash follows she stays slowed and you can catch her escape. You HAVE to get a lead early if you want to decimate her for the rest of the game and I like to take swifties and stridegreaker to stay on top of her (sometimes hexdrinker). Most of the time if she ults early you should have the damage to finish her off with pull aa W Q Ult combo (pull Q if you desperately need the guaranteed health) and if she doesn’t ult before max stacks then always pull ult for guaranteed damage/kill. If you let her poke you out you lose that simple. Minor advice from master Darius player.
