Gangplank vs Sett

Build a chain with Powder Keg (E): detonate the keg farthest from your opponent, and each keg whose area touches the previous one explodes too, all the way to them.

Last-hit minions and pop kegs with Parrrley (Q): a kill with the shot gives bonus gold, and so does a kill from a keg it sets off.

Save Remove Scurvy (W) for a key CC rather than for healing: it cleanses all CC on you, on a 22 to 14 second cooldown.

Cast Cannon Barrage (R) anywhere on the map to help a fight or cover an objective: each wave of cannonballs slows and damages in the area.

Get out of the center of Haymaker (W): it deals true damage there, and the sides only deal physical damage.

Keep your distance once Knuckle Down (Q) is used: he has no dash, and it's this spell that speeds him toward you.

Don't take a big trade unless you can finish it: Haymaker (W) stores part of the damage he takes as Grit, for a stronger shield and punch.

Don't stay grouped behind your tank: The Show Stopper (R) can slam them onto you, and the damage depends on their bonus health.
