Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
I just wanted show, what i think of the perfect Kayle build. This is my first build.
Reckoning: this is a very strong ability and great to harass. try to use it every time it's possible
Divine blessing: with this you can heal your self instead of going to base and the speed boost allows you to get the enemy.
Righteous fury: this ability kicks *** man!
In the early game you should harass all the time with "Reckoning". You don't have many items so your damage output isn't very strong.
Mid game starts for you at level 6 when you get your ultimate. With your ultimate you can escape from ganks and save your teammates.
At late game you should have a lot of ability power and your damage output is very high.
