Cassiopeia vs Aurelion Sol

Confidence mediumUpdated Jun 10, 2026

Overview

Pressure Aurelion Sol early to punish his weak kit and disrupt his scaling.
Use mid-range (Q) and (W) to force extended fights where (E) damage excels.
Deny his roaming by maintaining lane priority and wave control.

Trading pattern

Initiate trades by landing (Q) to apply poison, then spam (E) for sustained damage.
Use (W) to block his repositioning or escape attempts in trades.
Avoid trading if (Q) misses or (W) is down, as he can safely poke with (Q) and (E).

Danger windows

Avoid extended fights when (W) is on cooldown, as he can reposition or disengage easily.
Be cautious when (R) is down, losing your main hard CC to punish his positioning.
Watch for his attempts to farm or roam; punish by pushing waves and denying safe movement.

Early game

Punish pre-level 6 Aurelion Sol by landing (Q) to start trades and follow with repeated (E).
Hold (W) to ground his mobility when he tries to reposition or escape.
Push waves to limit his roam potential and keep him farming under pressure.

Power spikes

Level 6 (R) unlocks strong all-in potential by punishing enemies facing you.
First mana/AP item boosts sustained damage, enabling longer trades.
Respect his late-game spike after ultimate upgrade and Rylais completion, as he becomes harder to catch.

Win conditions

Force early trades with (Q) and (W) to apply poison and extend fights with (E).
Use (R) to punish him when he faces you during level 6 all-ins.
Maintain mid-range control to prevent his roaming and safely scale into mid-late game.

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