If you're like me, you like playing Gangplank in ARAM.
If you're a bit more like me, you like getting to the point.
Let's get started.
This guide focuses on dropping your opponents hard by applying massive AOE damage on Parrrley.
In other words, press Q to win.
MURAMANA: Essential. Take Tear of the Goddess first and get stacking it. Rush a Manamune early; the earlier you buy it, the better chance you'll get at finishing it into a Muramana for silly on-hit damage on your Q.
COOLDOWN BOOTS: You need these for the extra bit of CDR you'll need to keep pumping out the Parrrleys whenever they're available. No other boots will be as useful as these, except Merc Treads, but take those situationally.
INFINITY EDGE: I don't even think I need to explain why for this one.
RAVENOUS HYDRA: A beast of an item that is severely underrated on GP. Let me explain why.
AOE Lifesteal; press Q and proc hundreds of hp in healing by level 18.
Active: Much more useful than you'd think. It only has a 10 second cooldown, so spam it in teamfights with your Ulti going, and you're going to be dropping insane AOE damage.
Damage: Comes with a juicy +75 AD to help your Parrrleys do even more damage.
Synergy: Perhaps the most important reason; it synergises with the items in this kit. Read on.
: Another nice "on-hit" item that procs when your Q lands. Do AOE damage in a radius around your target and slows, which works nicely with your Ravenous Hydra and your Ultimate.
: Another item that's quite overlooked on GP. Take the Avarice Blade somewhat early in the game if you're falling behind on money. If you kill a minion with a level 5 Parrrley and an Avarice Blade in your pocket, you'll be racking up the $$$$$$ in no time. Additionally, this item is yet another AOE On-Hit item, which syngerises perfectly with Iceborn Gauntlet and Ravenous Hydra.
That's all you need to know about the items.
