Urgot (A.K.A. Mr. Garbage)

          Urgot is an adc, with a good combo of abilities. If you his an enemy with his AOE you can use his Q (Acid Hunter) to target the enemies that have been hit. This is good for attacking when the enemies are sitting   AT the turret. You don't need to dive for a kill. To use his ult well, I would bait the main damage dealer on the enemy team, and switch spots with them. This can use the turrets to your advantage, or your own teammates in a bush. Anyways, for a good Urgot build I would go with Berserkers Greaves, Bloodthirster, Runnan's Hurricane, Statikk Shiv, a second Bloodthirster, and an Infinity Edge. If the enemy isn't building very much health but they have a lot of armor, I would trade the the second bloodthirster out for a Blade of the Ruined King. The passive will help you melt through their armor, and the active is good for saving yourself and dealing a ton of damage.

Lissandra, The Ice Bitch

          I just played lissandra for the first time, and she is SO OVERPOWERED. All of her moves have crowd control effects. It's ridiculous. Anyways, for her build get Sorc Shoes, Archangels Staff, Rabadon's Deathcap, Rod of Ages, Rylai's Crystal Scepter, and Abyssal Scepter. This Build will give you a ton of damage and still have a lot of defense. If you want, trade out sorc shoes for Zhonya's Hourglass late game.

Rammus, The Greatest Tank Ever

          Rammus is a tank with a really unique passive. It lets him convert a percentage of his armor into attack damage, so you want to focus on building armor. This of course depends on how the enemy team is built. If the AP toons are fed and doing a lot of damage, build magic resist and health. Otherwise, build Ninja Tabi, Thornmail, Sunfire Cape, Warmog's Armor, Spirit Visage, and Guardian Angel. Like I said, if you get into trouble against ap, rush Spirit Visage and Guardian Angel. Use this build to absolutely demolish anyone attacking you.

Darius! MASTER OF KS!

          Darius is a top lane bruiser, and he is notorious for kill stealing and also being insanely overpowered. Building bruisers is very easy, but you have to do it according to the enemy team. With Darius, Ravenous Hydra is a must have. If you don't have enough lifesteal, you could get a Bloodthirster. You could also get an Infinity Edge for when you want to be able to crit. Since Darius is a bruiser, You are generally going to want to get 2 defensive items. I would get 1 armor/health item (Randuin's Omen), and if there is more than 1 ap character on the enemy team, get spirit visage as well. Find out who is dealing the most damage to decide on what boots to get.
