Hi I'm gaz, I'm a lowly plat player that enjoys theory crafting. Sometimes my ideas are ****. But other times I stumble upon something good. When I do, I try to perfect the build by testing it. This Kayle build is something I have been refining over the years, and decided to post it again due to the recent item changes and Kayle buffs, which makes this build really strong at the moment, in my humble opinion.

Items:
Rush boots to help Kayle through the early game.

Rageblade is really good on Kayle, especially now that it's a mythic. The mix pen it gives is great for this build.

Hullbreaker suits Kayle well since Kayle is good at split pushing, and Kayle has good base damage so you can build her a bit tanky. The regen let's you stay in lane, the canon minion buff will help you siege, the armor and MR is really good since this build has a lot of HP. The HP also scales with Demonic embrace and Titanic Hydra. Last but not least, the extra movement speed hullbreaker now gives is huge on Kayle, since she isn't very mobile.

Around the time you hit level 16 you should be able to get Rylai crystal scepter. Level 16 kayle + Rylai gives the slow effect on every auto attack and damage dealing ability.

Same for Demonic Embrace. Just like Rylais it gets triggered by the Kayle passive cone. Also ensures you deal damage vs high HP units.

With Titanic Hydra you get scary AoE. Now you dish out tons of hybrid damage, which is hard to counter. And you are really beefy which will makes it really hard to take you down.
