Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Hi this is my first build so feel free to comment. I decided to make a gangplank build because I think playing with him is funny.
Getting attack damage runes are good for Gangplank. Magic resist runes make you stay alive when theres ability power user enemy on your lane.
Make sure you always last hit creeps with parley because it gives extra gold and dont worry about your mana because you got clarity.
I think you should have heal and clarity as summoner spells because gangplank drains mana too much and in early game you have low health and heal will be your guardian angel in early game.
