MittePut E behind the exit they want rather than directly on top of them, because Aurelion Sol gets much nastier once lane trades and river fights force people to choose between walking through Singularity or giving up space
In lane, ask which enemy spell makes your Q illegal and do not W first; his clean turns start after that answer is spent, when flight actually changes the beam instead of announcing yourself
Treat side waves and objective setups as places to pre-build bad terrain for the next fight, and get there early enough that the enemy has to enter through your zone, because Aurelion Sol stays unusually live in long games even after rough starts
Fly once the enemy has already spent the spell or position that makes your beam fall apart. In lane, that usually means waiting until their interrupt, burst trade, or jungle support is no longer the first thing that happens when you move forward. In skirmishes, W is strongest when it changes the line of your Q or lets you arrive over a wall after the fight has started to take shape, not when it announces the fight by itself. If you are unsure, ask whether the flight creates a longer beam, a safer exit, or a worse retreat path for them; if it does none of those, keep walking instead.
Aurelion Sol's damaging Abilities break down enemies into stacks of Stardust, which permanently improves each of his abilities.
Aurelion Sol channels his dragon breath for a few seconds, damaging the first enemy hit and splashing reduced damage onto nearby enemies. Each second the breath is channeled directly at an enemy will deal bonus damage, which is improved by the amount of Stardust that's been collected. This ability collects Stardust if the target is a champion.
Aurelion Sol flies over terrain in a targeted direction. While in this state, he can cast other abilities. Breath of Light no longer has a cooldown or maximum channel duration and deals increased damage while flying.Astral Flight's remaining cooldown is reduced whenever an enemy champion dies after being recently damaged by Aurelion Sol.Stardust increases Astral Flight's maximum range.
Aurelion Sol summons a black hole, damaging enemies and slowly pulling them toward its center. This ability grants Stardust each time an enemy dies within the black hole and for each second an enemy champion is caught inside it. The center of the black hole executes enemies who are below a certain percentage of their maximum health. Stardust increases Singularity's area as well as the execution threshold.
Falling Star: Aurelion Sol crashes a star into the earth. This impact deals magic damage and stuns enemies while also granting Stardust for each enemy champion it hits. Gathering enough Stardust transforms Aurelion Sol's next Falling Star into The Skies Descend.The Skies Descend: Aurelion Sol drags a giant star down from the heavens with an increased impact zone and increased damage, knocking up enemies rather than stunning them. A shockwave then spreads from the edge of the impact zone, which damages and slows the enemies it hits. Stardust increases the impact area of both Falling Star and The Skies Descend.
