Sett vs K'Sante

Start your trades with Knuckle Down (Q): you rush toward your target, and your next two autos deal bonus damage based on their max health.

Cast Haymaker (W) right after taking damage: the stored Grit gives you a shield and extra damage, dealt as true damage in the center of the punch.

Don't back too early at low health: Pit Grit (passive) increases your health regen based on your missing health.

Stand between two enemies before Facebreaker (E): grabbed from both sides, they're stunned, otherwise only slowed.

Grab their tank with The Show Stopper (R) and slam them onto their carries: the damage around the impact depends on the bonus health of the target you grab.

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.
