Kayle is a underestimated champion in which lots of people think he is not that great. If played well he can be very powerful. I don't write multiple essays in my builds so I just try to sum it up. Hit the enemy with your Q followed by righteous fury, its pretty straight forward. Follow this build and you can be hitting really hard. Kayle can solo almost any champion with his ult if your good. Very good for team plays as well. Early game weaken enemies with your Q and E for a big advantange.

A quick question people may have is why 2 dorans rings? Kayle players know that he can be very squishy early game. 100 HP is huge beginning of game. 15 ability power is great because MOST of kayles damage is is AP, Righteous Fury can hit hard early game. 5 mana regen. The mana regen is VERY important. After 2 dorans rings you have 13 mana regen with the 3 from masteries. Since you get your divine blessing second, youll be able to spam heal on yourself and others as well. Lots of people arent fans of dorans ring, but its key to keeping kayle alive and strong early game. Lots of builds say hes too weak early game, 2 dorans rings is the fix. :) , when you need items slots later just sell them. Again I don't think a very long explanation is neccessary. But Guinsoo's Rageblade is a MUST buy for Kayle

Ive been doing very good with him lately with a recent match as 15-0-4
