Hi every one this is my first build .I gonna try to do my best to make this builds one of the best of gankplank.

In runes I take armor penetration for the quintessences for tank .
For mark I use attack speeds because you do a lots of dommages on 1 hits but whit a lots of speeds you can kill a team whit all the dommages you are able to do !!!
For seal I use crit chance at the start of the game you harasse a lots whit those crit chance.
And for glymph i use crit dommage because you have 100 % crit at the end of the game !!!

i start whit a brawlers gloves after I go whit avarice blade . before i did my boots i do my tears because you have so much spells to do and attack when covert in manamunes if you did it to late this will be realy bad but if you did it quick you will never short of mana !!! After my tears you do boots of cooldowns because you want to use your ult and your parrey all the time for kill whit parrey or for help whit your ult in a team fight. Whit my avarice i do youmuu ghostblades for the armor penetration and the active very strong in a team fight !!! After a infinity edges for the crit and the crit dommages !!! And for the last i do 2 phantom dancers for crit, attack speeds and move speeds for people running whit low life !!! And if you have a good game you can sell your boots and buy a bloodthirster for be inkillable !!!!

In team works gankplank will never be in front of the fight whit this builds !!!! He will come 3 seconds after the start to do a lot of dommages to every one in the fight . Whit his partener in line he will harasse a lots but the first thing he will do is the last hits whit his parreys to got a lots of golds. GP must use his ult at every time a fight start or when a ally is chase by an ennemy for save him or to kill the ennemy .

For the farming gp must always last hits !!! THE MINIONS WHIT PARREY !!! GP is one of the most goold dependant of the game . Each time a creeps is low life you must do PARREY . Whit your raise moral you got more dommages to kills minions at lvl 2 .
