Verdict: Naafiri is slightly favoured — Cassiopeia wins 46.33% of 1,580 games, and Naafiri pressures 4 of the 7 stage windows in the plan below. Play it patient and win your windows.

At a glance

Miasma turns assassins off — ground the dash, petrify the dive, and fang the helpless body that was supposed to one-shot you.

Track: Naafiri's W — Hounds' Pursuit (26–18s cooldown). The lock-on pack dash starts her dive — stand near minions to body-block the hounds.

Do

  • Hold W strictly for her dive path
  • Face her engage so the R stuns, not slows
  • Punish every farm-approach with Q poke

Don't

  • Waste miasma on wave or spacing
  • Turn your back during her commit
  • Chase resets past your own miasma

How to beat Naafiri as Cassiopeia: the early game

Naafiri has almost no way to reach you safely — she has to walk through your Noxious Blast and Twin Fang poke just to get in range, and her Pack dogs die instantly to a well-placed Miasma. This is one of the most lopsided lanes in your favor: as long as you don't walk into a jungler gank, you should be poking her to nothing by level 5 without ever taking a real risk yourself.
