First of all Thanks for taking your time to check this, this is my first post and I hope this will get some variety in your build pool for Sett mains.

this is still testing so if I ever learn any new build i will post it too, but for now I hope this is some help to you all.

Also if you have any advice on how to improve this post please tell me, since i am new in this and i don't know a lot on how to give every little detail and make it extra fancy.

To start off with the game, you want to check your match up, if you're against something that will get close face to face against you like a yasuo/yone, you'll want to get a doran's blade, if you're against something you'll have to get away or something that will poke you a lot, get a shield.

When you get to lane, it's important you harass your enemy with your E and you hit them a bit with hail of blades, then once you get your Q, it's time for you to go for killer trades, try to get close and stun with your E (since you have extra damage from cheap shot), then it's the time to use the true power of hail of blades Sett, since the runes allow you to do an extra hit with any auto reset, you want to AA - AA - Q - AA - AA, that way you get a fast and powerful 4 punch combo, that's why you want to get two points in power in your runes instead of just one and then attack speed.

try to use that combo as often as possible, always waiting for your Hail of Blades to charge before going in for a trade.

as told before, your W in this case is not your most powerful attack, so you can use it against champions which have a passive shield like Malzahar or Yasuo.

When you get Prowler's Claw, you can use it on minions (if you can't use it on champions) to get close and E the enemy.

Prowler's Claw is an important asset to prepare for ganking other lanes, since this will give you the mobility you need to assassinate the enemy adc, even if you flash over a wall.

Also, you want to remember, this is NOT a Tank build, since you'll go for Assasinations, this build is to go in, kill and get out, you are a powerful glass cannon, so don't expect to be a front line if you don't insta kill the carry of the enemy

This is the star of the show for top laners, it works for almost everything and you'll be of great help to your team if they are in need of a tank.

For this Build you want to get as much HP as you can, this will make your W really powerful in battle and your next Auto Attack do massive damage with Shield Bash.

Also to notice that you'll get Massive size since you'll go Frostbite Gauntlet, so the Mecha skin is a fun add to it.

To start you'll want to always get a Doran's Shield, then once you get to lane don't go straight to fighting, first at least charge your Grasp of the undying and then go for some poke with your E and some Autoattacks.

the time to kill is when you get your level 2, Go for your W and then try to go for all ins, the trick is to fight saving your W for last, saving your E to secure a full blown W with true damage in the center is optional, once the enemy has charged up your grit, try to land a fully charged W and hit the true damage, then go for an Auto Attack to get the Shield bash and do extra damage, repeat this process and you'll do massive damage and also endure a ton of damage, once you get 2-3 extra items you'll be a massive and steady front liner, since you'll also get a huge hitbox thanks to the Gauntlet
