He pokes in bursts, you damage in streams — close to Q range on his cooldowns and the DPS war is no contest.

Read from Cassiopeia's seat: which stage windows this plan plays for against Aurelion Sol.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Cassiopeia's instant poke freely punishes Aurelion Sol's slow wind-up kit from level 1 |
| Level 2 | Cassiopeia | Cassiopeia's damage lead compounds as Aurelion Sol has no fast trading tool to respond |
| Level 3 | Cassiopeia | Same trend continues — Cassiopeia's combo scaling outpaces his ramping poke |
| Levels 4-5 | Cassiopeia | Singularity's 12s pull and percent-health execute cancel out your Twin Fang lead |
| Level 6 | Cassiopeia | Your Gaze cancels his channels and his Falling Star stuns you — level 6 is a mirror |
| First item | Cassiopeia | Your item spike is one-off; his Stardust stacking is permanent, so it evens out |
| Two+ items | Cassiopeia | Permanent Stardust and a 1250-range Falling Star let Aurelion Sol dictate the late fights |
Cassiopeia wins early — Breath of Light is a channel he has to hold on you from 750 while your Noxious Blast reaches 850, so every attempt to bank Stardust costs him health. Punish each channel, shove the wave he needs to stack Cosmic Creator, and he has almost no early trading power against your instant poke. Track Astral Flight is 22s at rank 1 and 16s at rank 5 — while it is down he is a stationary battery.
