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.
Ezreal is probably one of my favorite champions. I love the fact that 3 out of 4 of his abilities are skill shots.
Mystic Shot - Your bread and butter when it comes to AD Ezreal. Applies 110% of his base attack damage. The synergy with Sheen is very good when Sheen boosts your AD by 80%.
Essence Flux - This ability is pretty much just a little bit of damage. It is boosted by AP, not AD, but since the recent healing removal and other various nerfs, it isn't as good as it used to be. The good thing is it bypasses minions, which Mystic Shot doesn't do.
Arcane Shift - A blink ability. I love it, and use it a lot when moving across the map, and especially for initiating a fight between someone. The homing shot can do a decent amount of damage even when not applied with AP, especially early game. A very good way to kill someone early game. Arcane Shift > Mystic Shot > Auto Attacks > Ignite.
Trueshot Barrage - A very awesome ability. Infinite range, can clear minion waves, and can decimate champions. I see a lot of Ezreal's using this as an execution skill similar to Demacian Justice from Garen, however I find it helpful to cast it during an initiated team fight to give our team an edge.
Start off with a Saphire Crystal and two health potions. I go mid when I play Ezreal, you should too, he is a very, very good mid character. Use Mystic Shot to last hit minions. That is your main objective because you need money! If the opponent in mid allows him/her to be vulnerable to a Mystic Shot, go ahead :). Once you have enough money, or if you die, buy Sheen and then go for Boots.
Boots depend on the enemy team composition. Ezreal uses armor penetration so don't even think about using Sorcerer's Shoes. If they are a heavy caster team, Merc Treads. Heavy Melee DPS? Ninja Tabi. Don't EVER get Beserker's Greaves. I used to play with Beserker's Greaves, but they are really only good on a select few champions. There are just so many more, better, options.
Now get Wriggle's Lantern. I am in love with this. Attack damage, lifesteal, and the active is useful for map awareness. I am always placing wards in the river, near Dragon, near Baron, in the bushes in mid, etc. It is VERY useful to make sure you know when they are shooting for a gank, or for when the teams are doing Baron/Dragon.
Now start building your heavy damage items. I cannot stress how important it is to buy 3 B.F. Swords instead of completing Black Cleaver, then the 2 Bloodthirsters. I usually don't get time to complete Trinity Force, but if you do have the time, get it.
This is my 2nd build, I would appreciate any comments you have. I am very annoyed at the people who -1 builds and don't comment. What are you afraid of? Only -1 if it really needs it.
