HEY GUYS
This is my build for gankplank.I hope my informations are usefull
and i hope u enjoy it
SO THUMBS UP :)

Grog Soaked Blade
As of this current patch, Parrrley no longer applies the Grog Soaked Blade debuff. Note that healing reduction will not stack with any other healing reduction debuffs (e.g. Ignite, Executioner's Calling).




Parrrley
Helps you farm. In team fights, use it on the enemy carry. Try to stay back and avoid enemy fire in the early parts of the battle.Plus use is as last hit on minions for more gold

Remove Scurvy
For escaping, Ghost and this ability will get you out of some ganks. Good players, however, will space out their stuns in a gank so that Remove Scurvy won't get you very far. In team fights, use it to keep yourself out of heavy AOE fire.


Raise Morale
I prefer to use the mana to farm or harass with Parrrley. Forcing a lane opponent to heal denies them much more gold/xp than killing a few allied minions. Use before a team fight if possible. Always use it to push towers.


Cannon Barrage
AP scales poorly on this ability. Magic penetration, however, will give it some extra mileage. In team fights, wait until the enemy has committed to the fight before laying it down on the battlefield.

Runes:
- 5xGreater Mark of Furor
- 4xGreater Mark of Malice
- 9x Greater Seal of Resilience
- 9xGreater Glyph of Malice
- 3xGreater Quintessence of Malice

I used to advocate Magic Resist per level Glyphs and Seals. I still think that they are a viable option, however I think for the moment Gangplank is so fatally flawed that no runes can truly save him from caster burst damage. Focusing on mana regen seals and cooldown glyphs at least presents you with some utility in the laning phase. Now that Parrrley damage is physical, the only way you will do any respectable damage with it is to get armor penetration runes. This is because enemy armor naturally increases as the enemy increases in level, while magic resist remains constant.

Exhaust
Exhaust a viable option in a team battle to cripple the enemy physical DPS. Spending one point in improving it can increase the damage you do with Parrrley by reducing the target's armor, but usually, it will just be for one shot. Teleport/Clarity and Ghost are my prime picks most of the time.

Flash
Flash is a great choice for summoner spell cuz it helps u to escape from many fights or reach the target at the right position to kill him


Ghost
I most often use this to escape ganks, or catch up to an enemy to deal a killing blow with Parrrley. In team fights, I use it to kite the enemy if they try to focus me. They will quickly give up since otherwise the rest of your team will destroy them. Cannon Barrage should have them slowed, so it shouldn't be too hard to kite them.

Other option:

Teleport or Clarity
However, Gangplank still does need an expansive farm to do a viable amount of damage late game. He is heavily reliant on what he can farm in the laning phase of the game. As such, Teleport and Clarity are the best recommendations because it allows him to stay in the laning phase as much as possible and farm.

General Strategy:
Gangplank can be played in a solo lane, but can easily be outmatched by better solos (Annie, Teemo, etc). Strategy for a solo lane can be difficult, since to be a good solo you should be able to do at least 2 things well:

1. Control your lane through sustained harassment
2. Farm minions and maintain gold/xp earnings on par with (preferably better than) your opponent

For Gangplank, #1 and #2 are accomplished through use of Parrrley. Being a melee champion, it is difficult in a solo lane to score last-hits with melee attacks without being harassed into oblivion. It is therefore necessary to stay back at range and use Parrrley to last hit. The problem, however, is you won't have sufficient mana regen to use Parrrley for both #1 and #2. There are several options:

A. Have your team help you get Golem buff to start the match. If another ally needs the buff more, you can...
B. Re-spec with mana regen runes, change item build to support mana regen (not recommended, as you won't need it as much once you are roaming with your team)
C. Focus on harassing (you'll make basically no gold, and your opponent might just out-regen your harassment or use Heal)
D. Focus on farming, neglect harassing entirely until returning to buy "Stage 2" items

I tend to go with options A or D if I am solo-ing as Gangplank. This requires you to sit back and avoid being harassed while still scoring last hits. Once your opponent hits level 6, they will likely be looking for a way to kill you with some kind of spell chain (usually Flash/Ghost/Ignite/Exhaust + nukes/stuns). If you tower hug enough they will get frustrated and leave your lane to gank another lane. Call them missing in action. If your allies heed your warning, your lane opponent will have lost out on gold/xp in exchange for zero kills/assists.

Once you hit "Stage 2" items, you should now be able to harass and farm much more without concern for your mana pool. Your Parrrley can do a surprisingly high amount of damage at this point, and you can quickly swing control of the lane to your favor. Always be mindful, however, of any spell chain that they might send your way. You are still quite fragile at this point.


Notes on Cannon Barrage:
If you are on a highly organized team, you can prepare your allies for an incomming enemy ganker and place a well timed Cannon Barrage that may even out a 2v3 gank situation and net you or your allies a kill.

In general, you should always be watching for opportunities to cast Cannon Barrage since you will be the first person on your team to hit level 6. If you hear that "an ally/enemy has been slain" you should immediately check out where all the action is taking place and determine if a Cannon Barrage is warranted.

If you score a Parrrley crit that takes your opponent down to about 200 hp, drop a Cannon Barrage slightly behind them. Their natural instinct will be to recoil back toward their tower upon being crit down to low health. Ghost in and chase for the kill.

Be mindful of Tristana (Rocket Jump), Corki (Valkyrie), Kassadin (Riftwalk) and those champions who have Flash. They can easily make your Cannon Barrage be a complete waste by jumping out of its range instantly. For best results, use Cannon Barrage when your opponents have their escape spells on cooldown. Try to bait them into wasting these abilities and then go for the kill.

Ganking:
Gangplank can leave his lane to gank, but good opponents will call their lane opponent missing, and other lanes will adjust to avoid being ganked. Also, at level 7 without any items, the expected value of Gangplank's Parrrley damage is somewhat low. Cannon Barrage might help, but without a targeted stun the effectiveness of a Gangplank gank is highly variable. With Gangplank, you are taking a big roll of the dice on ganking. I prefer to stay in my lane until I have hit "Stage 2" items before making any serious attempts at ganking.

When you do gank, use Ghost and run in shooting. Lead their escape route with Cannon Barrage and start melee attacking. Cast Parrrley again before they get to their tower. This is especially useful if you show up late to a fight and the enemy is retreating with low health. I have scored many a double kill this way, Ghosting in with guns-a-blazin'.

Play Video not good resolution though but it's ok :) THUMBS UP
