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.
pick any summoner spell you like. something about kayle, her kit seems like it would be good for hunting down your target. she can add range to herself, speed herself up, slowdown the enemy, and if things get scary, you will have your ult to save you (or any ally) from messy situations. the early game could potentially be a bit difficult, but tough it out through that and you could very well win the game. personally, i see potential in this build. but what do i know?
the items in this build synergize well with each other. with this build you get a lot of useful things. crit chance, full cooldown, attack speed, lifesteal, and movement speed. and maybe for a better chase down, rageblade could be swapped out for a frozen mallet. and a black cleaver could help get rid of the enemy's armor. and maybe even a wit's end would work on her. one interesting thing about kayle is that she could have ruunan's and a hydra even though it is pointless because there are better items out there. with kayle, you could either start with a dorans ring or dorans blade. or if you want to go ahead and start the game by building an item, get a long sword to start.
