At a glance

Pure artillery — you lose the range war at every distance except fang range. Dodge-walk forward patiently; one grounded root and he dies.

Track: Xerath's E — Shocking Orb (Stun, 13–11s cooldown). His only CC — dodge the orb and his artillery never converts into a kill.

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

Level 1XerathXerath's Arcanopulse outranges every tool she has, so level 1 is free poke he never pays for
Level 2XerathEye of Destruction slows her out of fang range while he keeps poking from a thousand units
Level 3XerathShocking Orb comes online and any stun he lands turns a poke exchange into half her health
Levels 4-5XerathXerath's mana passive keeps him poking while she has to ration Noxious Blast and her fangs
Level 6XerathRite of the Arcane hits from 5000 range, so he threatens her health bar without ever being in hers
First itemXerathHer first item closes the damage gap, but Xerath still chooses the range every exchange happens at
Two+ itemsEven / skillShe wins any fight she actually reaches, and with peel in front of him she rarely gets to reach one

How to beat Xerath as Cassiopeia: the early game

Xerath outranges you significantly with Arcanopulse, so early levels require patience — don't walk up mindlessly, and instead punish his mana-heavy poke pattern by waiting for him to whiff or run low before pressing an advantage. His total lack of mobility means any read on his position lets you close in with your own poke and threaten a bigger trade.
