Garen vs K'Sante

Trade with Decisive Strike (Q), then Judgment (E), and back off: the Decisive Strike silence stops your opponent from answering with spells.

During Judgment (E), stay closer to your opponent than to their minions: the nearest enemy takes extra damage.

After a trade, back off until Perseverance (passive) kicks in: without recent damage taken, you regenerate part of your health every second.

Activate Courage (W) just before the bulk of the damage: you first gain a shield and tenacity, then a longer damage reduction.

Save Demacian Justice (R) to finish: its true damage grows with the target's missing health.

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.
