AP Tank Leona

          This build is going to be for an AP tank Leona. Leona is a tank with AP scaling for her abilities. Her scaling is actually really good, and she also has 2 stuns to go with it. If you combine AP/defensive items with one really good defensive item, you can have a lot of damage output and still be in the middle of a teamfight soaking up damage. The build can be bought in any order you see fit, but I buy in this order: Mercury Treads, Zhonya's Hourglass, Iceborn Gauntlet, Athene's Unholy Grail, Rylai's Crystal Scepter, Randuin's Omen. I like it in this order because I get my armor on first, and usually I am going up against bruisers on Top.

Veigar, The Tiny Master of Evil

         This is going to be a short post, but this is my build for Veigar. Veigar is a mid mage, with a lot of damage output. The only problem is that you can see his main ability coming a mile away. To counter this, throw out your E stun and then use your dark matter and baleful strike to do a TON of damage. The build is as followed. Buy Crystalline Flask and 3 pots instead of Boots of Speed and pots. Then get Athene's Grail, Chain Vest, Abyssal Scepter, Sorcerer's Shoes, Deathfire Grasp, Rabadon's Deathcap, and Zhonya's hourglass. When you are deep into a game with extra money, sell your boots for a Void Staff. That is all for Veigar's build. I tried this and had around 700 AP.

Lifesteal Build Re-vamped

         So a few months ago I tried out a lifesteal build for Katarina, and it worked really well. The only problem is that they nerfed Katarina's AD scaling, so she is underpowered unless you use AP now. This lifesteal build is for Tryndamere, a melee AD carry. I would get, IN THIS ORDER, Berserker's Greaves, Ravenous Hydra, The Bloodthirster, Phantom Dancer, Blade of the Ruined King, and Randuin's omen. You could switch it out for a second Bloodthirster if you have enough attack speed but want more lifesteal and damage. The Randuin's Omen is for people who like having more resistance to burst characters, but if they don't have any, just switch it for one of the 3 exchangeable items. You will have less armor and health, but you will deal WAY more damage. If you get really far into the game and have a TON of unusable gold, sell your Greaves for a second Bloodthirster. You will do even more damage, and the passive stacks.

This build can be used for any melee AD carry. I made sure.

Kha' Zix, the Voidreaver

          Kha'zix is an AD bruiser that can go mid, top, bot, AND jungle. This makes him very versatile. Kha'zix's abilities are a claw attack for Q, a ranged skill shot for W, A jump attack for E, and a stealthed movement speed bonus in which he does extra damage (+ even more bonus damage to isolated targets). His abilities use mostly AD scaling and have a unique way of leveling up. Every point he puts into his ultimate, he can evolve 1 ability. If he chooses to evolve claws, his Q ups damage dealt to isolated targets. If he chooses to evolve spike racks, his W shoots in 3 lines instead of 1, and heals him if he is within the explosion radius. If he chooses to evolve wings, his E makes him jump much farther and does more damage. If he chooses to evolve camoflauge, his ult makes him stay stealthed for longer and he can use it a 3rd time. There are only 3 ults, so you cannot evolve all of them. I would recommend evolving spike racks 1st every time, while the other 2 are left up to your best judgement.
          For a nice bruiser build I would recommend using the Ninja Tabi or Mercury Treads (Depending on whether the enemies are AD or AP heavy), Bloodthirster, Ravenous Hydra, Atma Impaler, Mercurial Scimitar, and a Sunfire Cape. You can trade out the Atma Impaler or the Mercurial Scimitar for an Infinity Edge if the enemy is AP or AD heavy. On Thursday I would like to try out and publish an ADC build for Kha'zix. I will tell you if it worked or not. For now, here are some pictures of Kha'zix.

This is Kha'zix's only skin, Mecha Kha'zix.

Quinn Build

          So, the new character Quinn is another AD carry, and there aren't many builds out there. Luckily, I am the greatest at item builds and can help you out! It is a fairly good build. I went 15 and 4 with it, but in my defense my teammates were incompetent. They kept feeding the entire game. Anyways, the build is Berserker's Greaves, Blade of the Ruined King, Infinity Edge, Runaan's Hurricane, The Bloodthirster, and The Last Whisper. Late game you can trade out the last whisper for something more expensive like the Mercurial Scimitar or the Black Cleaver. You may need to play her a few times before getting good, but she's worth it.

New Build for the AP Teemo

          The build for VI did not turn out well. There isn't enough attack speed to make a difference, and to make it so there is, I would need to sacrifice too much attack damage.
          On a lighter note, I thought I would post my ultimate AP carry Teemo build. It is literally the best build I have ever used for him, even the ones online. Make sure if you use this that you get it in this order. It consists of Berserker's Greaves, Malady, Nashor's Tooth, Runaan's Hurricane, Liandry's Torment, and Rabadon's deathcap. This should leave you with about 2.35 attack speed and 300 ability power. Teemo's movement speed is really fast too, so don't be afraid to poke a TON. The only thing you shouldn't do with Teemo is dive, because if you do that, turrets will kill you in about 2 seconds flat. Teemo is really good late game to kill the dragon, AND Baron Nashor. You can solo the dragon, and ruin Baron with about 1 other person. GL and HF.

Vi's AD Carry Build

         Vi is an AD character, and she has an awesome passive attack ability. Basically, every 3 hit does a percentage of the target's health in damage and it has an armor break. The percentage dealt is also increased based on how much AD she has. Because this is based on the fact that she has to hit the target 3 consecutive times, she would need a lot of AS. For this build, I would get Berserker's Greaves, Bloodthirster, Phantom Dancer, Ravenous Hydra, Statikk Shiv, Randuin's Omen. This build may be weak on attack speed, but I will find out later this week.
