I don’t play as much as I used to but I believe I’m still the highest rated Kayle support main so I’ll share what I believe is the best build right now. I decayed from 500ish lp masters and played a few to get masters back recently.

Runes: Aery > Mana Flow > Transcendence > Gathering Storm. Resolve 2nd Bone Plate > Revitalize.

Skill order Lvl1 E, 2W, 3W, 4Q. Max W>Q>E

I buy control ward level one and put it in the ward light thing in river or raptors bush depending on side I’m on.

Items: I go dark seal every game. Mikaels into Knights vow into honestly whatever you want after that. The tank support item

I take exhaust over heal every game, I just find it more valuable. Lucidity boots every game as well

Any questions lmk

How do you play against her? Especially in top it feels very hard, even more so when Irelia takes exhaust. Mid I feel like its a bad matchup but more manageable since its a shorter lane. I take exhaust in both roles against her, rush swifties and max Q.
