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.
Hey, that's my first build ever, but truth to be told - it was tested and I got 13 wins out of 13 games, all of them having great statistics. Anyways, please comment and help me improve it in some way if you have any ideas!
Usually I take this two, Clairvoyance and Clarity, because I have somehow supportive role, but feel free to substitute the Clairvoyance with Teleport, Ignite or Heal for example. I wouldn't recommend Flash, Ghost or Rally, but it really is your call.
Always start Q-W-E-E-E-R-E-E and then, depending on what role are you having, choose either Q or E and max it first without touching the other one. In most cases my team needs a healer and I often choose "Divine blessing" as the second most important skill (third actually, but ultimate is not negotiable - it is a must at levels 6, 11 and 16).
My build is still new and I haven't tried magic penetration marks, but I think the attack speed is just as important, stacking greatly with Malady and Guinsoo. As for the glyphs, cooldown reduction per level would also be a great idea (I take the AP for early kills, because Kayle can really use gold in the beginning to stop the other team from developing). Mana regen seals, she has to have them as her mana regen is not good enough in the beginning and I end up frequently without any mana.
I have tried different masteries, trust me guys, 21/0/9 works best on this hero. She can support okay with 9/0/21, but turns into a real destructor with the offence focus.
--Start with Sapphire Crystal and 2 HP pots. You need the mana.
--When you have enough gold, come back and do directly Swiftness Boots. If you return to base early, buy just the normal boots.
--Your third item is Guinsoo's Rageblade, maybe the most important in the whole build, giving you attack speed and ability power which stack with your "Righteous Fury" in an epic way.
--Buy a Sheen whenever you have the money and continue, building it into Trinity Force.
--Next item is Zhonya ring and usually the game is over around here, but if not:
-> continue with a Malady, 'cuz the new one is really badass for Kayle. Anyways, I wouldn't recommend it build before any of the other items.
-> Sixt item could be some Critical Strike, having in mind that it would really overpower you. I had the situation on critting one poor Ryze at level 18, taking about 1/2 of his life and finishing him quickly with Righteous Fury (which by the way I believe can crit too, cuz once I had an epic Quadra with it, but didn't expect so much output at the last hit).
WHAT TO DO IN GAME
Each game start on a lane, preferably with a friend you know and you are sure he is capable of helping you. Never go middle, there are so much more heroes that do better than you and doing this could be a big mistake.
Harass the enemy champions with "Reckoning" and try to keep them away from XP line. If there is a squishy on your lane try to attack him with your partner and get an early kill. As much kills as possible, actually. Heal yourself or your partner, use your Clarity when you need it and try to stay away from enemy attacks, because you will have almost no way to defend yourself. Use your E spell to clear waves of minions and if you start attacking a champion - ALWAYS start by activating this spell and try to hit as much as possible, because it will hurt.
Mid and Late game
After getting your Rageblade you will see the difference! You can now solo champs of the other team, having your ultimate ready for just in case. When pushing towers - tap your E spell to maximize the damage output and just watch their team go sad. In teamfights you have to do 2 simple things, but they are a MUST:
1) Activate "Righteous Fury" and start hitting the group of enemy champs. You will see their health go down quickly. Whenever someone starts running - Q and if that doesn't finish him, maybe someone on your team will have an ability, ready for the kill.
2) VERY IMPORTANT: Use your ultimate on your carry whenever you see the other team focusing him. This will give him about 3 seconds more life, hopefully wasting their ultimates and getting them ready to be finished by your might. If you succeed in this you win the fight, and probably even the game.
That's it for now, when I get to my other PC I will upload a screenshot to see what I am talking about. Thank you, and again, please comment!
