Welcome all or any who read this, I should warn you that this is my first guide. I play Gangplank as my main, almost only, champion and over time i've been finding better and better ways to build him around his Parrrley to dominate early game and late game turn into any old Attack Damage dealing champion that can pick up or finish off many kills with his Parrrley. I'm not gonna include much detail as much of him is self explanatory.

Obviously for being focused around his Parrrley you want to get that maxed as soon as possible and then I would recommend your Remove Scurvy so you can get out of binds/fears/slows/silences/etc and stay out in the battle/lane if needed.

Gangplank effects huge roles in teamwork. His Raise Moral can help you win team fights, help teammates escape bad fights or help take out turrets quickly. His Cannon Barrage can make sure you or teammates finish kills, even from across the map. With the Iceborn Gauntlet built you can slow enemies from a range with your Parrrley and with the Infinity Edge built, or just with your passive, you can slow with your basic attacks both allowing teammates to catch up to help or slow down enemies chasing low health teammates.

Nothing too important about farming but, if you get a Faerie Charm early on, it's a good idea to finish off minions with your Parrrley for extra gold.
