Cassiopeia vs Xerath

Confidence mediumUpdated Jun 10, 2026

Overview

Use mid-range spacing to apply poison and force extended trades where sustained (E) damage wins.
Avoid Xerath's long-range poke by stepping forward only when his key cooldowns are down.
Punish Xerath's immobility by holding (W) to ground his (E) and force close fights.

Trading pattern

Start trades by landing (Q) or (W) to poison and slow, then chain (E) for sustained damage.
Hold (W) to punish Xerath's attempts to reposition or to ground his (E) stun.
Avoid trades if (Q) misses or (W) is down to prevent being punished by Xerath's poke and stun.

Danger windows

Avoid committing when (E) stun is available to prevent being locked down.
Do not move forward while Xerath charges (Q) to avoid heavy poke damage.
When (R) is up, avoid facing him directly without (W) or (R) ready to respond.

Early game

Farm safely and look for (Q) to apply poison before committing to trades.
Respect Xerath's poke by avoiding overextension without (W) ready to block or ground his follow-up.
Step forward after Xerath uses (Q) and (W) to punish his cooldowns with extended (E) trades.

Power spikes

Level 6 (R) lets you punish Xerath when he faces you, increasing kill threat.
First mana/AP item boosts your sustained damage and mana for longer trades.
Track Xerath's level 6 (R) and first item spikes to respect his increased poke and kill pressure.

Win conditions

Win extended fights by landing poison and chaining (E) while using (W) to deny his mobility.
Use (R) to punish Xerath when he faces you during all-ins or forced engagements.
Maintain mid-range control to force Xerath into unfavorable trades and deny safe poke.

Tip: For Cassiopeia vs Xerath, read overview, trading pattern, and danger windows first for a fast Mid lane check.
