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.
Pros / Cons
+ Crit items are very gold efficient on him ( Way of the Wanderer)
+ Strong laner
+ Scales incredibly well
+ Works well with a lot of champions
+ Extremely mobile
+ Great at split pushing, his power spikes are very noticeable
- Prone to getting ganked
- Very hard to play at top level
- Need a lot of game knowledge to effectively make use of him
- End game team fights are awkward if no knock ups
If Orianna starts E, start Q, if she starts Q, you start E. Basically what happens is, if she starts E she can't really harass you, and you can safely farm with Q. In the case she starts Q, you can harass her pretty heavily with E as you can dodge her Q and get in good damage. As the lane goes on, she becomes stronger and stronger, and especially if she gets a blue buff, she'll likely be able to poke you down a good amount. Hopefully you have a Vampiric Scepter or she doesn't punish you hard, but it's hard to win 1v1 as you'll get ganked probably if you go too aggressive. So be smart about the lane, and just try to farm, kill if you see their jungler somewhere but otherwise try to farm.
Start Boots of Speed vs Syndra as she's very skillshot reliant and if you're able to juke her Qs and trade effectively, you'll slowly win the lane. Start E and do your best to juke her Qs at level 1, you can E through creeps and through her if she's out of position or missed a Q. The early levels 1-3 aren't too bad, but as she starts leveling up and hits 6, she has a ton of kill pressure vs you. Also if you ever get ganked, it's pretty rough for you as she has good CC. Do note though, that you can block her Q E combo as long as you Wind Wall is in front of the ball.
Tips And Tricks
A cool trick is getting an Auto Attack off during the knock up of your Q, before immediately ultimating them. For example, if you have a charged tornado, and you E-Q the enemy champion, auto him before ultimating him, for some extra damage in your combo. You can only get off the extra auto if you do it quick.
When trading during lane, make sure you have an escape route via your E, if you dash towards them make sure you can dash away as well, be wary of the HP of the creeps and which ones you E'd through.
Basically, any displacement ability from your teammates allows you to use your ultimate ( Janna's Monsoon, Trundle's Pillar of Ice, Lee Sin's Dragon's Rage). You don't always want to spam Last Breath right away the moment you're able to. For example if your Blitzcrank uses Rocket Grab on an enemy, you can wait for them to reach Blitzcrank before using it, whereas with Thresh's Death Sentence/ Flay you only have like a quarter second to do it. In the case where Lee Sin's Dragon's Rage is about to knock multiple enemies, you can wait for it to knock up the other people, then cast Last Breath. So be a bit patient with it.
After using your ultimate, you have 40% Armor Penetration, so try to use it relatively early in Team Fights and 1v1's so that you're much stronger after. A lot of people don't realize you become stronger after using it, so keep it in mind.
Try and weave Auto Attacks with your Q, make it as efficient as possible. Auto Q, Auto Q, etc etc.
When running around to get your Flow back, running long paths instead of pacing back and forth regenerates it faster, so try and do long strides.
Using your Wind Wall is very important, it blocks all projectiles and can be the difference between winning a fight or losing one. It does not block spells that aren't projectiles, such as Force Pulse, Final Spark, Incinerate and Summon: Tibbers. The Wind Wall also shoots out a bit in front of you, so it'll take a couple times to get used to it.
