Dorans for safety

Cull for Scaling and extra Cut Down Damage

Ornn's Skill Max Order: W → Q → E
Matchup Tip: Use your E to cancel Ornn's dash to his Q. If he Qs you, stand in between the rock and him and instantly vault him during his dash, which will counter his dash and you won't be stunned. Replicate this throughout the matchup.
Level 1: Quinn Cheese level 1 and then side step right away to juke his Q. After this, run him down with autos until he hides under turret. You can now zone Ornn off the wave by doing this. You hard win level 1, but just be mindful that his Q comes up before your E does by 3 seconds. His Q does a lot of damage, so try not to get hit by it.
Level 2: Ornn has W or E, but he'll likely go W if he's behind. His W prevents him from being slowed by your E, so if he time's it correctly he can make your trade worse. However, you're not afaid of Ornn so look to play aggressively.
Level 3: Save E to cancel his E dash. If Ornn throws Q, Stand in between the rock and him and vault during his E dash to cancel it. Learning this mechanic is important to win this matchup.
Level 6: IOrnn R sets up great ganks. If you are feeling confident, you can cancel Ornn R with your E, but you have to use it at the picture perfect timing. It is really hard to land, but if you suspect death, then try it as a last resort. Vault him right before the R comes to cancel his R if you want to try this, but it is difficult. Otherwise, let his R hit you and try to E him when he dashes onto you.
The matchup isn't that bad if you take these tips into consideration.
First, Orrn's W makes him unstoppable, and therefore, try not to use vault on his when it's active (the bellow's breath flame spitter ability).
Next, Quinn's E can, in fact, cancel Ornn's E dash SO LONG as he doesn't collide into terrain.
The reason is becasue colliding into terrain stuns all enemies around him, but if he doesn't collide with terrain, then his E is programmed as a simple dash, and Quinn's e cancels regular dash abilities.
To beat Ornn, firstly avoid being near Walls, and if he throws his Q rock out, make sure to walk away from it.
If ornn wants to charge at the Q, I recommend not to try cancelling his dash with your E because if you're at the wrong angle or mess up the timing, then he will cancel your vault and stun you.
Try to juke his stun, and with this, I typically stand near his rock pillar, and when I anticipate that he will dash towards it, I'm 1 step ahead and leave the target range before he charges so that I can bait out his E.
If he dashes and doesn't hit you with his dash, then you are free to engage on Ornn and make him cry.
Are you ready for one of the most exciting interactions in the game? If you vault Ornn while his R2 is coming after you (the timing must be perfect). you will ACTUALLY cancel Ornn's ult lol.
The reason because Ornn must collide with the elemental, but your vault is a brief knock back that pushes him backwards for a split second, and if you time it correctly, you will cancel Ornn's ultimate.
This requires EXTREME practice, so please be careful with it lol. Practice :) You will E him the milisecond before his R hits his body.
When you get lord dom's, you will start to deal damage to ornn, even if he stacks armour.
