Hi there

I made this build for myself and i wanted to share it with other Gangplanks mains(this build is useless if you don't know the champion). I'll finish this guide as the preseason goes on. If you want a full AD build just go and look the other 5000 guides.

Pros

Survivability

Can 1v1 bruisers

Good enough damage(enemy team can't just ignore you)

Cons

Awful in low elo

Can't one shot

You need to know how to play him

The best rune for gp bruiser right now is without a doubt Grasp of the Undying, every time you poke in lane with your Q it gives you 5 health so you will leave laning phase pretty tankie.

Font of life: really good in teamfights your ulti and barrel will procc the heal for your entire team. Now your ultis in early and mid game are more of a support type(since it heals), you should get the "Fire at will" upgrade first since it will keep the enemys more time inside the ulti.

Conditioning: perfect for gp, normally u play really safe until 15-20 mins in the game even if you lose cs so i really recommend this one. But in cases of hard matchup that just straight out kill you (riven,malphite,fiora,etc) you should use Iron skin or Mirror shield depending on damage.

Overgrowth: it will help you stack more health with grasp, and even if you can't farm because of hard matchup you just have to be in range of dying creeps.

The ultimate hat: this rune is core on the new gp, it reduces by a lot your ulti cd with it you will be able to have more impact in the game in the early-mid game. And believe me Mana Flow is not worth it.

Transcendece: 10% cdr at lvl 10 is really nice, but in my opinion between this one and Gathering Storm is really just your choice i prefer the cdr since this is not a full ad build and Transcendence lets you overcap cdr and get more ad.

Rush Jaurim's fist, after that build a sheen and sit on it until you have Sterak's gage finish trinity force and start building a defensive item (Spirit visage or Randuin's omen), build death dance for the heals ,if you are ahead you can buy death dance third but i don't recommend that unless you have to fight a lot(get a vampiric scpeter and finish the defensive item), boots depending on situation, and finish with a nice phantom dancer for the damage reduction, and the occasional crit.

I will try the new changes and update the guide as i learn more, still, this build works.
