Hi! Im Chease and this is my Guide for Sett toplane. I started playing league in seson 9 and I'm playing Sett since his release

Precision:

Conqueror - Best keystone by far, allows Sett to deal more dmg and sustain in fights.

Fleet Footwork - Fleet allows you to sustain on heavy poke lanes + gives you movment speed that allows you to get to your targets faster.

Triumph - Sett doesn't use mana so Presence of Mind is usless and I don't realy use a lot of life steal to make use of Overheal.

Legend: Alacrity - Best option when enemy has low to no CC.

Legend: Tenacity - My favourite rune by far, allows Sett to use his abilities in fights and reduces slows to allow him catch his targets.

Legend: Bloodline - As I said I don't use life steal as much and other two runes are just better for Sett.

Coup de Grace - Take it if you build a lot of life steal and you are sure that you won't be on low hp.

Cut Down - Just don't take it.

Last Stand - This rune is ideal for Sett, his passive allows him to stay on low hp making Last Stand deal more damage than Coup de Grace.

Resolve:

Demolish - Good rune if you want to split push but it doesn't give you any power in fights.

Font of Life - It doesn't give you anything on 1v1 lane but if you want to play Sett more like support or on support lane its one of best choices.

Shield Bash - Personaly I don't think Shield Bash damage is worth losing runes like Second Wind or Unflinching.

Conditioning - I don't use it but I think it can be good vs tank to scale even better wihout losing anything.

Second Wind - Best secondary rune for Sett. Gives you even more sustain during laning phase and scales better than Bone Plating.

Bone Plating - Take it vs melee matchups that you are not comfortable to play against.

Overgrowth - Take it when you don't need Unflinching.

Revitalize - IMO the worst rune choice in last row of Resolve, heal and shield gain is inferior to health or W shield that you would cast if you were able to move or had more hp so you would survive more/deal more dmg.

Unflinching - Take it when you need a lot of tenacity.

Mythics:

Stridebreaker - If enemy team is very mobile go for it.

Goredrinker - Since stride changes in 11.13 and MATHEMATICLY CORRECT build Goredrinker is very good on [Sett]] go for most of the time.

Trinity Force - Good item for split pushing and 1 vs 1 fights.

Sunfire Aegis - Build it when you are behind or you need to solo front line but u want to deal some more damage.

Iceborn Gauntlet - If you need to be more tanky go and you want to slow enemies then go for it.

Turbo Chemtank - Good item if you need get near enemy team and solo frontline for your team.

Boots:

Plated Steelcaps - Build it when enemy team has a lot of AD damage. Must have vs range AD toplaner like Vayne or Gnar.

Mercury's Treads - Tenacity enables Sett to fight in team fights. Best item choice vs champions with a lot of CC like Leona, Morgana or Anivia

Legendary items:

Blade of the Ruined King - I don't really like this item, it gives you just pure damage and life steal but its still good item. Build it when you need to split push so you can fight enemies when they come to contest you. Also its very good item vs Mordekaiser.

Hullbreaker - Stats of this item are the best stats for Sett so if you need to split push/fight 1v1 then go for it.

Anathema's Chains - Also great item for split pushing and 1v1 but also very powerful vs feed carries. Go for it if you want to make enemy carry cry :D

Sterak's Gage - Health, Damage and shield scaling from max hp and champions hitting you. Ideal item for burst deny, team fighting and damage.

Spirit Visage - Health, Magic Resist, Ability Haste, SHIELD and HEALING increase making this item ideal with shielding and healing items like Sterak's Gage, Gargoyle Stoneplate, Blade of the Ruined King or Ravenous Hydra and runes like Second Wind, Conqueror and even Setts abilities Pit Grit and Haymaker.

Gargoyle Stoneplate - Your other items will give you a lot of HP so Gargoyle Stoneplate active will give you a lot, in addition Armor, and MR will make you even tankier.

Randuin's Omen - Build it vs team with 2+ Critical hit users or vs heavy AA reliant teams.

Abyssal Mask - Good item if you need to peel for your team and if you need a lot of HP with MR.

Warmog's Armor - Build it when you have a lot of resits to make them more gold efficient. It has also very good synergy with Titanic Hydra.

Titanic Hydra - One of most broken items for bruiser at the moment. Titanic Hydra gives you HP and AD for all your bonus HP.

Ravenous Hydra - Cleave passive applies itself on your AA, W, E and R. Because of that you will deal more damage and sustain in fights.

Force of Nature and Dead Man's Plate - Additional tank stats + movement speed allows you to get near enemies.

Chempunk Chainsword and Thornmail - Build Chempunk Chainsword if you need Grievous wounds but don't need armor. Build Thornmail vs AD enemies that are willing to hit you to proc Thornmail.

Black Cleaver - Good item vs teams that stack a lot of armor, also it's very good item if you want to peel for your AD teammates.

Death's Dance - Another survive burst item, build it when somehow enemy team is able to burst you down thru Sterak's Gage.

Guardian Angel - Build it if you are really ahead or you are main target of enemy team.

Silvermere Dawn - If you are main target of enemy abilities like Realm of Death or Nether Grasp.

Knight's Vow - If you have a lot of defensive stats and your carry is getting bursted in team fights build Knight's Vow to save your carries from dying.

Pit Grit - Sett alternates bettwen left and right punch wich is faster and stronger. Use his right punch to trade, for example last hit a minion with left punch then if your laner is in range hit him with right punch. In addition Sett gains 0.2-2 health regeneration per 5% missing health. This make Sett realy hard to poke down from lane but its still possible. Use it to your advantage by trading hard vs champions that don't have a lot of sustain, this will make you ahead in health wich is very important stat early game. Also if you get Ignited you can use Health Potion and your absurd health regen from Pit Grit to outheal yourself from it.

Knuckle Down - You can use it to chase down enemies and most importantly use it as AA reset.

Haymaker - This is iconic ability of Sett. Use it when your Grit bar is full to gain as much shield and deal as much damage as possible.

Facebreaker - I still see that some players don't understand how this ability works. If you have enemies (Champions, Minions, Monsters) behind you and in front of you using Facebreaker you won't just grab them, you will also stun them for 1 second. Using this stun mechanic you can guarantee your true damage from Haymaker.

The Show Stopper - Use this ability to either engage into enemy team or to suppress high priority targets. Remember that this ability deals more damage if you grab enemy with more BONUS HP + It has hidden scaling from your bonus AD (120%).

Runes and builds you see above are good because they accomplish this things:
1. Generally good
2. Enables Sett to carry games (not solo carry!).
3. Enables you do a lot even when you are behind.

As of builds I really can't say that one is better than the others because there will be scenarios when you need something else than big chunky Sett dealing 3k true dmg but 200 magic resit/armor big boy front laning for his team. Best advice I can give you all is to think what do you need to win? Is it 1v9 big shlong toplaner that can't get near that 3 marksman champions with galeforce or more tanky boy that can get near with his chemtech to help his team kill them or perhaps you have 4 donkeys sitting mid for no reason and you need to split push? Remember that league of legends is not solo game but team game and YES you can solo carry games by 1v9 BUT not all games are winnable by 1v9 or generally winnable at all. Focus on your mental and try to play with your team.

CS'ing tips:
In laning phase remeber to CS, its the most important thing in the game. 3 waves of minions are worth more than one kill so if you get a kill but your enemy is 30 cs ahead in reality you didn't gain much. If you max W+E you can clear waves in a blink of an eye making it easy for newer Sett players.

Most basic combos:
Let's start with some basic things. If you AA twice and use Knuckle Down as soon as you see that your second AA dealt DMG you can use Knuckle Down to reset animation between sets of AA so you will avoid Sett delay between second and first AA animation.

Next lets talk about more advanced combos:
Facebreaker + Haymaker combos is one if not the best combo for trading as Sett. This combo GUARANTEES that you will hit your Haymaker true damage spot making first Haymaker max Sett very good especialy since his buffs in patch 11.9.

Facebreaker + Stridebreaker + The Show Stopper combo. You can Facebreaker oponents near you then instantly use Stridebreaker ative and use The Show Stopper to yoink enemy into your team whiout any counterplay by them.

Haymaker + Flash. Basicly you Flash at the end of Haymaker to move it or "Extend" it. I also see that still a lot of people don't know that Sett can Flash while casting Haymaker, so use this combo especialy in lower ELOs to abuse lack of knowledge from your enemies.
