Cassiopeia vs Syndra

Confidence mediumUpdated Jun 10, 2026

Overview

Use mid-range space to apply poison and force extended fights on your terms.
Pressure Syndra early to disrupt her sphere setups and limit her poke windows.
Respect (E) stun cooldown to avoid burst all-ins and punish attempts to reposition.

Trading pattern

Initiate trades by landing (Q) or (W) to poison, then spam (E) for damage.
Hold (W) to ground Syndra's movement or escape attempts.
Avoid trading when (E) stun is off cooldown to reduce burst risk.

Danger windows

Syndra is most dangerous when (E) stun is available to set up burst combos.
Avoid extended trades before level 6 when you lack (R) for counter-engage.
Respect Syndra's burst if caught without poison or (W) to control her movement.

Early game

Use (Q) to apply poison and start trades before Syndra sets up spheres.
Avoid committing when (E) is available to punish movement or dashes.
Maintain medium pressure by forcing Syndra to cast defensively and miss poke.

Power spikes

Level 6 (R) greatly increases kill threat and punishes Syndra facing you during all-ins.
First mana/AP item boosts sustained damage and allows more confident extended trades.
Track Syndra's level 6 (R) and first item to respect her burst and adjust spacing.

Win conditions

Win extended fights by applying poison and maximizing (E) damage while denying Syndra's repositioning with (W).
Use (R) to punish Syndra when she commits and faces you.
Pressure Syndra early to limit her sphere setups and reduce her poke and all-in windows.

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