At a glance

He pokes in bursts, you damage in streams — close to Q range on his cooldowns and the DPS war is no contest.

Track: Azir's E — Shifting Sands (22–16s cooldown). His shield-dash to a soldier — engage the window after he burns it.

Do

  • Step forward the moment his key spell whiffs
  • Land Q, then machine-gun E while poisoned
  • Ground his retreat path with W

Don't

  • Eat poke at his max range for free
  • Walk forward with his full rotation loaded
  • Spam E unpoisoned — the mana dies fast

How to beat Azir as Cassiopeia: the early game

Azir's soldiers require mana and setup he doesn't have before level 2, so your Noxious Blast poke chips him for free while he's stuck auto-attacking minions. Stay just outside his max soldier range and punish any overextension with Q-W. His trading pattern is passive early because he can't threaten all-in without soldiers stacked, letting you control the wave and zone him off easy CS.
