At a glance

A DPS check he fails — poison every step-up, ground his approach, and E-spam him off the wave.

Track: Garen's W — Courage (22–12s cooldown). Damage reduction on cast — your burst only lands full once it is down.

Do

  • Q-poison every last-hit attempt
  • Drop W Miasma on his approach path
  • E-spam only poisoned targets

Don't

  • Stand inside Courage range with W down
  • Spam E without poison and drain your mana
  • Push past river without vision

StageFavouredWhy
Level 1CassiopeiaYou concede level 1 with one ability, but at 2-3 your Q-into-Twin-Fang poison chain out-DPSes his short Decisive Strike trade.
Level 2CassiopeiaOnce poison is up, Twin Fang refunds off it and you spam it — your ramping DPS beats his spin-and-disengage in any drawn-out trade.
Level 3GarenHis 4-5 spike: ranked Decisive Strike silences your Twin Fang and Courage lets him close and out-burst your short-range poke.
Levels 4-5GarenCourage's damage reduction and tenacity blunt your burst and your stun, and Decisive Strike breaks the slow you wanted to kite behind.
Level 6CassiopeiaPetrifying Gaze stuns him out of his frontal all-in, but his Q silence and Courage still make raw trades a coin-flip — call it even.
First itemCassiopeiaYour first-item poke spike and his bruiser spike roughly cancel; neither cleanly owns the lane at this point.
Two+ itemsCassiopeiaLiandry's plus passive AP scaling makes you a kiting shredder who grounds his engage with Miasma and melts him in extended fights.

How to beat Garen as Cassiopeia: the early game

Levels 1-3 are yours if you stack poison cleanly. Concede level 1 — you have one ability and no chain yet — so farm from the edge of Noxious Blast (Q) and stay out of auto range so he cannot get a free Decisive Strike trade. At 2 and 3 you come online: tag him with Q, then Twin Fang (E) refunds off the poison and lets you spam it, out-DPSing his spin-and-leave. Every poison tick also counts as being struck, so Perseverance stops regenerating — the chip stays on him. Drop Miasma (W) where he wants to walk for the grounding, not the slow. Respect his 8s Q silence: never throw Twin Fang the instant he steps up.
