Hello and welcome to my guide. I realize there will probably be many mistakes and issues at first so I welcome tips and questions in the discussion. I welcome any build test results and anything else of the such that you can think of. PM me for more questions.

Alright so Ezreal does not have the best farm at first so you wanna make sure you get as much farm as possible in the begging so that you can get the Trinity Force and farm a little better. You can always farm across the map to with True-Shot Barrage. For instance if minions are taking down a turret in another lane. Most important point is FARM or die.

Some people will argue my Flash and Barrier spells. Some will want flash and ignite, However Barrier saves your life if you cant finish off a kill you always have True-Shot Barrage to get the last hit. Trust me you would rather have less deaths then more kills. Barrier counters Ignite but Ignite does not counter Barrier.

Some people might say that Ezreal's only good ability is his Q cause its the only thing that does damage. However his other ability's are also helpful you just have to use them correctly. Like a lot of strong Q's his is a skill-shot that cannot pass threw minions so here is where his other ability's come in. With his Arcane-Shift this can be used to go through walls and get away from ganks. But it can also be used to coordinate Ezreal's Q. If you fighting someone they will usually stay behind minions. So use your Arcane-Shift to teleport to the side of the minions and fire from the side of the minions for a better hit. This will up the hit-ratio and make harassing alot easier.

Pro's:
Alright so if you build and farm right Ezreal will be able to do massive damage with his Q and other ability's. With True-Shot Barrage most enemy will not be able to get away because u can just snipe them down no matter how far they are. Lastly with Arcane-Shift you can easily attack and run if your being chased just teleport through a wall if they flash you just Arcane-shift.
Con's:
Although Ezreal can do massive damage like most ADC's him especially can be very squishy and is often targeted. But do not worry to much with the frozen mallet added in he can still do damage and not get one shot-ed. Another problem is that Ezreal is not the best for farming this is very important to all ADC's but you must make sure to get the last hits and use his W + Trinity Force to get efficient farming otherwise your screwed.

Its not like you should not creep or help the other lanes. But when you do make sure you always bring your support with you. Ezreal being as squishy as he is will be easily targeted and ganked he is best in the back of the group shooting from behind all the tanky people. So remember stay with someone to support you anyone.
