AS Sett Top/Mid you have two options. Be super Aggressive, or be Super Aggressive.

With the build, you are meant to fight people, you WANT to fight people early to get ahead in gold and try for a early cuck on the laner. For Top going W first adn then E helps witht his as if they fight you, you will deal true damage and shield unless they flash out of it which you can follow with your own flash or flash to escape. Then E helps with pulling them in and stunning them. Depending on who you are against this works pretty much everytime, unless it is a ranged top or mid laner, then your best strategy and to play safe and CS, waiting for your jungler to assist you and get ahead.

With Sett jungle, you want to be the controller, control every objective and vision opportunity.

Sett jungle is super strong, stronger then most expect as you can kill Scuttle super quickly with E and Q and can tank dragon and solo it due to your W passive and true damage from it.

With my experience from playing him jungle, Id reccomend to go Blue buff first and then clear red side as it helps with the cooldowns on your W and Q ability to clear faster and you already heal tons from your Passive, so red would just be a little extra help.

Ganking is a pretty difficult part but once you have Boots and Q up, you can easily run the laners down, even better once your level 6 as you can R them into your team and slow them for a better wya to secure a kill.

Now no matter which role you played, you are the backbone of your team.

Past the 25+ minute mark is when Sett will be at his best, depending on how many items you have built. You NEED to engage for your team, you have to lead the fights because your want to be hit. You want to be taking the damage for your team and set up the kills and be ready to hit your W.

I hope this build takes off for Sett. It is the Correct way after all.
