Gangplank vs K'Sante

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.

After two Ntofo Strikes (Q) hit you, back off or dodge the next one: it becomes a shockwave that stuns and pulls.

When he charges Path Maker (W), get out of its line: nothing stops him while he charges, then he rams straight ahead and his dash knocks back and stuns.

Don't fight with your back to a wall when he has All Out (R): if he knocks you into it, you go through, he hits you again and follows, far from your team.

Focus him during All Out (R): he loses max health, bonus armor and bonus magic resist, but heals off his damage, so don't drag it out.
