“Sett is going to be all about CC and getting in close to chain CC you while dealing True Damage. It's not that this match-up is really extreme, but more or less impossible to get kill potential on them due to his overloaded kit. You need to avoid the center of his (W) otherwise you take a lot of true damage depending on how much damage you dealt to him. This will also shield him with the correct combo, however, since Setts release his (W) cool down got higher making it harder for him to spam it. It would be wise to constantly poke him from a safe range and avoid even remotely getting close to him. Glacial Augment is the best rune to help with this, effectively crippling his ability to chase or hold you down. The moment you get caught by his (E) CC. It is a very hard lane to go up against if you don't respect his speed and damage. I would highly recommend Glacial as it is absolutely crippling to his entire kit, making him have to flash to really get close to catch you. But that is my opinion, I prefer to target ban him.
“TL;DR - SKILL MATCHUP IN YOUR FAVOR. TAKE CONQUEROR. GRASP WORKS. SHORT TRADES EARLY LEVELS. DON’T LET HIM HIT YOU WITH W TRUE DAMAGE. DON’T STAND IN A WAY WHERE HE IS BETWEEN YOU AND YOUR FRIENDLY MINION. YOU BEAT HIM PRE-6 IF HE FUCKS UP W AND POST-6 STRAIGHT UP. IF YOU ARE LOSING EARLY WAIT TILL 6. DODGE W OR AT THE VERY LEAST GO TO THE SIDE OF IT SO YOU DON’T GET HIT BY THE TRUE DAMAGE. YOU CAN WAIT FOR HIS SHIELD TO DECAY. TRY TO KITE HIM. DON’T TAKE FULL AA DPS. LEVEL 6, DON’T STAND BETWEEN HIM AND HIS TURRET. HE CAN R YOU INTO TURRET AND INSTA KILL YOU. CORRUPT POT WORKS. DBLADE IF CONFIDENT. DSHIELD IF NOT SO CONFIDENT. NINJA TABI -> PHAGE.
Sett is a matchup that you can sometimes snowball off of but it is nevertheless a tricky one to play properly for Darius mainly because of his W shield. You’d play into him as you would into a Jax or a Tryndamere where you wouldn’t just stand in front of them an AA them. The trick is to use your ghost and your AA range to kite them. With Sett it gets a little trickier to do but he is still beatable in all ins in early levels if you are able to outplay his W. His shield decays rapidly (for 3 seconds) so it might be a good idea to kite around him until the shield goes off and then go back in. If he is between you and one of your(allied) minions, then he will stun you which will allow for Sett to use his W’s on you, leaving you no option but to take the true damage. This insta loses you the fight as he just deals crazy amounts of damage. His HP regen is also something to look out for as it comes into play later on into the lane. He essentially has built in rejuv beads which means that he will be able to survive through some of your poke later on. This means you have to switch between 2 playstyles during this lane to play around his strengths. You want to be playing the early levels carefully, poking him with Qs and backing off. His HP regen is a bit weaker early on so exploit it and take quick but good trades. The reason you want to do this is due to his W. This is his most powerful tool and disengaging before he can use the shield is the way to go. Sett is a lane where a Corrupt pot start would actually be a good option as your approach shouldn’t be to all in fight him. But people make mistakes so a Dblade or a Dshield start will allow for you to better punish Sett and force his flash/kill him if he missplays/mispositions/misses his abilities. Remember in fights to KITE him. If you don’t, the fight will be a lot closer as he can sometimes just bash your face in. And a fed Sett is a NIGHTMARE to deal with.You should try to poke him before he can use his W shield enough so that you get him low enough to all in him. You CANNOT cancel his abilities with your E. If you pull him during his W, he just moves with it. Use your superior movement speed if you have ghost to sidestep his W. If you feel like he is going to use his W, get really close to him and just run around him as the W is easier to dodge the closer you are to him. Once he uses his W and you have some HP left to work with, he is free food. You have to NOT take his full AA DPS though. KITE. If you find yourself getting demolished in trades, try to sustain up and wait for level 6 because you will be able to kill him in an all in at that point. Your ultimate is much better than his and this is the point where you want to be switching gears. His W damage scales to be quite high at this point and his HP regen comes into play so you want to be looking to just full all in him and kill him if you aren’t behind already. Building against Sett is similar to how you would build against a Darius actually. You are going to want to rush Ninja Tabi and then get a lot of health. Health is the only way to counterplay flat true damage. Runewise you will be looking to go for Conqueror most of the time. A niche rune that works well into him is Grasp of the Undying, as this allows for you to have MUCH better quick trades which is how you beat Sett.”
“Sett is kind of similar to darius, really hard to do much until level 9 in this matchup but it's also easier to survive then darius, basically don't take bad trades often early because his regen is ridiculous early game and you don't have the tools to extended fight him early on, make sure not to stand in the middle of his W, if he has a lot of grit built up then constantly be moving around so you don't get falcon punched, you can also E him to fling him behind you when he W's but you have to predict and anticipate it. You can sometimes get a kill with your ultimate in this matchup if he ever uses his W poorly but just be careful with trading, ninja tabi is also a great buy early against this champion because he autos a lot and you can kite him a lot with the MS. Another thing to note is you can E buffer his E so you can E right before he E's to instantly get away when he pulls you in.”
“Sett is a really hard to get out traded early game. He simply deals way more damage than you just by auto attacking you and when you decide to run away, he will use W to throw that extra damage (thankfully it's easily dodgable).
You could only go for a short trade if you see him use his Q or E to wave clear. Otherwise just farm up until you have at least PD.
Late game, if you play it right, you should be able to kill him in a 1v1.”
“A lot of people would say " Wouldn't Neeko win the match up easy with the auto range advantage" yes it's true but Sett has a lot of Health Regen to make up the damage neeko can cause. Executioner Calling can help in this match up but will slow your purchase of Boots and Blade of the ruin king. Sett can catch Neeko if he rushes Tier 2 Boots so make sure to keep your distance once he starts rushing with his Q. ”
“Early game might be tricky due to his bulkiness and huge damage on W. Dodge his Q with your E and path behind him while he casts W to avoid the true damage and beat him down after that. Just be careful that he doesn't ult you under tower post-6. You outscale him late game, though his W damage will still be very high once his grit builds up so be vary of that. ”
“Sett is pretty difficult for a lot of melee champions, and especially for Ornn since he doesn't really have a way to dodge Sett's W unless you can stick right up to him when he is casting it and move behind him. You can setup ganks on him quite easily due to his immobility but the issue is he can potentially 1v2 due to his kit being quite oppressive during lane phase. Farm safely and play for teamfights rather than trying to fight him in lane. Tabi rush helps and build bramble vest if he goes bork.”
“Do not fight lvl 1. Parry his W as his stun is not too predictable early game and his W does massive damage. You can also dodge his W with your Q in later levels. You out scale so if you are losing, farm under tower.”
“Sett will have more range than you typical melee champions that you fight thanks to his Pit Grit(Passive). Kite his Knuckle Down(Q) then fight him when it is down. Dodge his Haymaker(W), if you can't avoid his center or you will true damage from him. Juke out his Facebreaker(E) AKA pull. Try to peel off Sett in team fights. (Recommended Items: Blade of the Ruined King, Ninja Tabi's) (Sustained 1v1 Trades: Even) (Outscaling Edge: Warwick)”
“Don't get baited by the massive shield on his W. Otherwise this lane is pretty straight forward and we farm until 6, then win hard post 6. ”
