First League post and first post in a while. Still haven't figured out a way to make myself post more consistently... Anyways, I occasionally mess around with item builds in League and found this Ezreal build to be really fun. Initially, I just wanted my Q's to hurt a ton which it did, but I didn't realize the amount of burst this build actually packed. For example, E+Gunblade+AA one shot most squishies late game.
The core items in this build are Muramana, Statik Shiv, Gunblade, and Lichbane in that order. Since it takes quite a long time to finish the core, I usually end up skipping boots altogether. You can build anything else after that, but I generally stick with AP. Morellos synergizes with this build pretty well.
Muramana. For the physical damage bonus and mana sustain. Every Ezreal should build this.
Statik Shiv. We need this solely for the wave clear, so we can farm the rest of our core and finish our cull if we have one. The mid game damage from Statik is reasonably good too.
Gunblade. For the active and sustain. The heals are especially noticeable since Exreal's Q and E are single target.
Lichbane. For the magic damage and AP scaling sheen procs.
Morellos. The CDR allows us to spam more abilities plus the mana restore on kill or assist allows us to maximize Muramana's bonus damage.
Early Game. Play like a normal Ezreal would. Just make sure you're in a matchup where you can at least match your opponents wave clear. Mostly physical damage.
Mid Game. You should have Statik Shiv by now. Power farm. You're still weak until you finish stacking tear or building Gunblade. Make sure the enemy doesn't gain too much map control while you're farming.
Late Game. Look to poke down enemies and assassinate out of position squishies. Mostly magical damage.
