I'm Thedeadlyspoon aka ΤriΗard.I've been playing Gangplank since season 6 .I finished plat 2 in season 7 and got diamond 5 in pre-season.I got diamond playing gp, camille and yorick(yes this champion still exists). If you want to view my op.gg here's my name TriHard

Pros + Deals a lot of dmg to tanks + 1000 DMG crit that is AOE ignores 40% armor and slows + Scales very good into late game + Has a free qss with his Remove Scurvy

Cons - Really hard to play - Loses lane most of the time - No escapes

This is your first item in the game. The passive is perfect for gp and the mana is usefull in lane. This is your first powerspike

All the stats benefit gp. It is aslo your second power spike and you can kill your opponent. It is always fun when you can fight back

Its gives lethality that helps your barrels ignore even more armor. It also gives damage and some movement speed

It gives you 30% crit chance and you don't have to spend a lot of money to get it unlike Infinity Edge

It's a huge power spike for gp cause your barell crits deal 250% dmg insted of 200%. It also gives you crit which is a must for gp. And it gives you 70 AD

Helps you deal with tanks and the Last Whisper pen helps you delete squishes easier

If they don't have any tanks i prefere to get RFC over LDR cause of the extra crit chance

Kleptomancy Kleptomancy: It's the best rune for gp.It helps you survive laning phase better with the free pots and helps you get faster to your late game items Perfect timing Perfect Timing: It's a free one use Zhonya's Hourglass that helps you survive dives. And trust me, if the enemy jungler knows what he is doing he will dive you. Future's market Greater Glyph of Cooldown Reduction: You can back earlier and still have enough money to get sheen on your first back, which is huge in a hard lane. Cosmic insight Cosmic Insight: It's really usefull cause gp is an ability reliant champion, so having your cooldowns more often is huge

The ultimate hat

The Ultimate Hat: Your ult is great for teamfight so heving it up more often is really good.

Transcendence

Transcendence: The same as cosmic insight. More cooldown is good for you.

This part of the game is NOT fun for you. Your job is to survive. Don't go for kills, if your jungler comes and you're against someone like Vladimir who can 2v1 you ping your jungler back. Try to farm and poke your opponent with q. When you get a trinity forfce you can fight back so wait for that. Look at other lanes and use your ult there. It helps them and gets you assists. BUT if your opponent is someone who can't get to you easily like Nasus you can kill them after you get sheen. And remember, your lane goal isn't to kill your oponent. It is to survive and get gold trough farm and Kleptomancy

Farm in a solo lane till you get lvl 13 cause that's when your barrels are stong. Also you'll have Trinity Force and Youmuu's Ghostblade so you'll be able to 1v1 your opponent.

This is the part of the game where gp becomes a beast. Group with your team and go for fights. In team fights dont go in the frontline stay between the frontline and the backline. This will help you land combos at their back line also protect you from the enemy team

Thank you for reading my guide. This is my first guide so excuse me if it isn't that good. Any feedback will be appreciated.
