Galio vs Cassiopeia

Updated May 31, 2026

Overview

Galio must manage short-range trades using W and E to punish Cassiopeia stepping too close while absorbing her magic damage.
Apply lane pressure to deny Cassiopeia a calm scaling lane and avoid giving her space for extended E trades.

Trading pattern

Trade short bursts around Q and passive, then punish Cassiopeia stepping into W taunt range or predictable movement with E knock-up.
Respect Cassiopeia W cooldown as it grounds dashes and blocks engage; avoid committing when it's available.
Avoid extended trades where Cassiopeia can stack E damage; force quick trades and disengage before sustained damage builds.

Danger windows

When W or E are down, Cassiopeia can trade more freely; avoid extended engagements during these cooldowns.
Cassiopeia's R window is dangerous if you face her during engages; avoid facing her directly when R is up.
If Cassiopeia's W is available, respect her ability to ground your dashes and punish mobility attempts.

Early game

Use Q and passive to pressure Cassiopeia early and force her to miss Cassiopeia Q or W to reduce her trade threat.
Hold W and E to punish Cassiopeia when she tries to land Cassiopeia Q or commit to extended trades.
Push waves to create roam opportunities and leverage R to impact side fights before level 6 power spike.

Power spikes

Galio's level 6 R greatly increases map impact and skirmish potential.
Galio's first durability or AP utility item enhances survivability in trades and roams.
Cassiopeia's level 6 R is a major threat; respect its stun and slow during all-ins.

Win conditions

Use W and E to control short trades and punish Cassiopeia stepping too close to deny her sustained damage.
Push waves to create roam pressure and use R to turn fights around river and side lanes.
Absorb Cassiopeia's magic poke and force her into unfavorable short trades to prevent her from scaling safely.
