Hello guys. I am Master EUW Mid main and I have a lot of experience on Orianna. I discovered this awesome build just recently and I have been dominating my enemies with it. I believe it might get nerfed soon.

It's very good versus most midlaners as she outranges almost all of them and provides you with a lot of tower desctruction potential, however DO NOT DO this build if you are playing against Vel'Koz / Xerath , you will never be able to fully utilize the on-hit effect of the Nashor's Tooth as they will never be in auto-attack range.

You have to maximize the gold income early on , by not dying on lane , getting farm and maybe some tower plates. Playing with your jungle early on if you have priority on your lane can get you some gold as most jungles fight at scuttle and if you are there first you will be able to get a solo kill or maybe two. As soon as you get blasting wand +- recurve bow you can get more agressive, if u have the recurve bow + blasting wand u outdmg almost everyone in long trades except high dps champs ofcourse, (DPS = Damage per second). When you have the Nashor's Tooth you will be able to oneshot the backline of the wave (3 caster minions) and easily kill cannon with passive dmg + nashor's tooth passive dmg. Try to secure plates as getting them is now much easier thanks to the enormous attack speed + ability power that you get from Nashor's Tooth.As soon as you destroy the first tower look to go to a sidelane to get more resources there( waves/towers ). Before drakes/rifts/barons try to gain priority on your lane and potentially send someone there from the enemy team to clear the wave while you and your team easily secure the objective ( drake/ rift / baron ). Your scaling doesn't stop as you get your mythic item as 2nd and legendary item (rabadon in most cases) as 3rd so the longer the game goes the stronger you will be. The early game is the most important so try to not lose it all by going for bad rotations/trades/fights.

If this guide helped you, you can follow my twitch link as you can often find me coaching there or if you have any question about the game u can simply ask me.
