[Patch 25.11] Master OTP Season 15 Aurelion Sol Guide (+ Matchups Detail)

By Event Horizon
Introduction
Hi! I'm Event Horizon #Solar on EUW, and I'm a Master 200LP peak Aurelion Sol OTP. I've been playing Aurelion for about a year now and have thousands of games played with him. I made this guide out of passion for the champ and hope it is useful for both new Aurelion players and those looking to improve and climb. If you're on EUW feel free to add me on the client.

I update this guide every patch and include some thoughts on the patch notes in the patch history section in the very bottom section of this guide.

The style of this guide is text heavy rather than lots of visual aids so take your time as there is lots to learn.
Pros and Cons
Pros

1. He's a space dragon. Do I need to say anymore?

2. He has an awesome in-game power fantasy of going from one of the weakest laners to the best scaling champ that will single-handedly take over the game.

3. Aurelion Sol has a large variety of viable items and can easily adjust to enemy and ally compositions.

4. Infinitely stacking passive means you will always be useful late game even if the early game doesn't go well. He rewards patience and a strong mental.

5. His kit allows him to be viable in any meta as he is equally good at killing squishies and tanks.

6. His empowered ult, The Skies Descend, might be the most powerful ability in the game and can completely flip a losing game into a win when used correctly.

7. Great roaming potential. His Astral Flight resets on takedowns allowing him to roam to a sidelane, get a kill or assist, and fly back to mid.

8. His huge AOEs on Singularity and Falling Star allow him to control teamfights and skirmishes from a distance.

9. Aurelion Sol has an awesome personality in-game with over 30 minutes of voice lines, and a further 15 minutes on his legendary skin Porcelain Protector Aurelion Sol

Cons

1. Harder than might be expected. He's not easy just because you stand still and press Breath of Light, he's very vulnerable and only has Falling Star for self-peel.

2. His weak early game contributes to his difficulty but also gives you very little agency in the first 15 minutes of a game. In higher elos a weak early game is better punished.

3. Breath of Light requires you to stand still. Anyone that plays League will know standing still makes you vulnerable to skillshots and CC. Learning when you can safely use Breath of Light and Astral Flight is key to being a good Aurelion Sol player.

4. Aurelion Sol will usually lose lane because of the nature of his kit. Understanding and respecting this is also key to being a good Aurelion player.

5. Assassins and gap closers cause big problems once they get into melee range. Use your long range to stay safe.
Summoner Spells
Flash

Flash is essential. Aurelion Sol has very little CC and Astral Flight is not a reliable escape due to its cast time. Flash will help you get out of tricky situations or help pick up kills.

Teleport

95% of games I take Teleport. Its great for getting back to lane and general game macro.

Barrier

Great for keeping you alive in those really difficult lanes. Fizz, Ekko, and Zed are good examples of Barrier matchups.

Cleanse

If you particularly hate the Zoe matchup cleanse can help you get out of bubbles.
Runes
Primary

The Sorcery tree is essential for Aurelion Sol just like it is for most mages.

Arcane Comet is by far the best keystone rune for Aurelion and must be taken every game. It's great for poke in lane with Q taps and it scales decently. By the end of the game it will have done serveral thousand damage.

Manaflow Band is essential for Aurelion because of his mana issues and must be taken every game. It can be stacked quickly in lane with Q taps.

Absolute Focus is best suited for when you want to have presence in the early game. Transcendence helps with stacking as Singularity has a lower cooldown.

Scorch is for when you want to have presence in the early game. The early game damage helps poke with Q taps. Gathering Storm is great for the matchups where you won't be interacting with the laner so much or they heal through poke such as Yasuo, Yone, Vladimir, Galio, and Kassadin.

Secondary

The Inspiration, Resolve, and Precision trees are all viable for the secondary runes.

Precision is a higher risk higher reward option. The lane is riskier because you have no sustain but you have more damage. This has become the default for me. If you think you can survive the lane then the Precision tree is a good choice. Always take Cut Down.

Inspiration is no longer the default after the biscuit changes in 25.09. Cookies give you some sustain in lane and 90 permanent max HP. Free boots save you 300g.

Resolve is mainly for assassin or consistent poke lanes. Bone Plating is great for reducing combo damage of assassins like Akali and Fizz. Second Wind helps reduce poke damage from champs like Mel and Viktor. Pair these with Overgrowth.

For rune shards always take double Adaptive Force if you want early game aggression. 18 AP is good value. Take the haste shard for cooldown in scaling lanes. The only time to take the Health Scaling in the middle row of shards is when you are running Second Wind. For the HP shards in the bottom row most of the time take the flat +65 Health. Take the Health Scaling in safe matchups like Vladimir and Kassadin.
Items
Starting Items

Doran's Ring and two Health Potion every game.

Core

Every game your first two items must consist of Rylai's Crystal Scepter and one of Rod of Ages, Blackfire Torch or Liandry's Torment.

Rylai's Crystal Scepter into Liandry's Torment is the standard option in most lanes. Grab a Tear of the Goddess or a Sapphire Crystal on first recall to help with the mana issues. The mana items can either be sold later in the game when you need the item slot or the gold refund OR upgraded into Archangel's Staff or Blackfire Torch respectively.

Blackfire Torch into Rylai's Crystal Scepter is the riskier but more mana and damage option. Only do this in safe lanes, never against assassins.

Rod of Ages into Rylai's Crystal Scepter is the third option. Useful in difficult lane matchups like Yasuo and Yone or scaling matchups like Ryze and Kassadin.

Item Information

Rylai's Crystal Scepter is the perfect item for Aurelion Sol. Synergises insanely well with Breath of Light and Singularity. In an ideal world you would rush this item every game but Aurelion has mana issues. A Sapphire Crystal/ Tear of the Goddess/ Presence of Mind can help. Rylai's Crystal Scepter must be bought first or second every game. Don't be scared to build the Giant's Belt component before Blasting Wand in difficult lanes.

Liandry's Torment is the second most important item for Aurelion. AP and HP are great for Aurelion and the damage amplifying passive gives you a big damage spike. I would recommend building this every game after Rylai's Crystal Scepter. The only scenario I wouldn't buy Liandry's Torment would be if the enemy team are all squishies and high burst AND I bought Blackfire Torch first. In that case Blackfire Torch > Rylai's Crystal Scepter > Zhonya's Hourglass/ Banshee's Veil would be good.

Blackfire Torch is a good first item in lanes with low kill pressure because it gives enough mana to let you farm waves without running out. The trade off is no HP so you are very vulnerable which is why you can't rush this item vs assassins. When buying Blackfire Torch in lane you can either go for Fated Ashes first for wave clear or Lost Chapter if you want more a bit more AP. Most of the time Fated Ashes + Sapphire Crystal is better.

After buffs in patch 25.10 I believe Bloodletter's Curse is a core item now for Asol. He has consistently been one of, if not the best, users of Bloodletter's Curse. Bloodletter's Curse is also a great magic resist counter item when you have other AP champs on your team as it reduces the targets magic resist but I think it is good enough when solo AP. Aurelion can reach 4 stacks with Q or E in just 1.2 seconds. As a Haunting Guise item it naturally synergises nicely with Aurelion's kit. Build this 3rd or 4th depending on how urgently you need magic pen.

Zhonya's Hourglass is a great third item against heavy AD comps or high burst. Aurelion has no self peel except Falling Star so Zhonya's Hourglass can be a great way to stay alive or bait enemies. Can be useful against certain AP burst champs such as Syndra and Fizz as you completely dodge their R damage with good timing.

Rod of Ages was nerfed in patch 25.09 and I think ROA is meh on Aurelion Sol, it feels weak and can't be the default first item every game. Save it specifically for the really tough lanes and scaling lanes like Anivia and Kassadin. Rod of Ages must be bought first item for it to be worth it. Rod of Ages will make you weaker than usual before 20 minutes but once you get the level up on the 10th stack you spike hard. Will help keep you alive in difficult matchups while also giving mana. Follow it up with Rylai's Crystal Scepter and Liandry's Torment for a high HP battlemage build.

Archangel's Staff. I don't really recommend this item in the current meta, I think Rod of Ages is the better scaling item. If you bought a Tear of the Goddess in the early game and the enemy comp has a lot of burst or dive then the item can be worth buying for the shield.

Rabadon's Deathcap is a core mage item. Aurelion Sol doesn't have the best AP ratios and his passive Cosmic Creator makes him a stat checker later into the game so I usually won't buy Rabadon's Deathcap until 3rd or 4th item. The item and the components Needlessly Large Rod are expensive but the price is being reduced to 3500g in patch 25.10.

Void Staff is great for getting through magic resist especially on tanks. Best when you are solo AP due to the 95 AP. Can be bought as early as 3rd item.

Banshee's Veil is a good item vs heavy AP comps or engage. Useful for stopping charms and hooks.

Shadowflame is ideal against squishy comps or when you need to kill an enemy quickly. I usually prioritise defensive items after Rylai's Crystal Scepter > Liandry's Torment but Shadowflame is a good source of flat magic pen. The ability crit below 40% max HP is useful against sustain champs as they get less time to heal.

Horizon Focus is a popular item in Korean high elo. This item is good if you are behind and need a cheap damage amplifying item. The vision passive can be really useful in jungle skirmishes and teamfights.

Riftmaker is a personal favourite item. Really good when teamfights are long because of tanky or high sustain comps. Synergises great with the other Haunting Guise items. Build 3rd or 4th. Paired with a Void Staff or Bloodletter's Curse you will melt tanks.

Cryptbloom has fallen out of the meta and I wouldn't recommend it. Void Staff and Bloodletter's Curse are far superior for Aurelion Sol when you need to get through enemy magic resist.

Morellonomicon is an antiheal item and Aurelion Sol is great at applying antiheal because of his huge AOEs and item burns. It's best to sit on the Oblivion Orb component as it applies the same antiheal passive and then upgrade to Morellonomicon as your 6th item.
Abilities
Passive: Cosmic Creator

Aurelion Sol's damaging abilities against enemies generate him permanent stacks of Stardust, which gradually improve his abilities.

Breath of Light: Bursts deal bonus magic damage based on the target's maximum health. This is why Aurelion is great at melting tanks.

Astral Flight: Range is increased equal to 62.5% Stardust. The range increase is notable in my opinion every 100 stacks.

Singularity: Outer and inner radius increased equal to 15% Stardust, and the execution threshold is increased. Another reason Aurelion is great at killing tanks.

Falling Star/The Skies Descend: Impact radius increased equal to 15% Stardust.


Q: Breath of Light

Initial Cost: 30 / 35 / 40 / 45 / 50 Mana

COST: 8.75 / 10 / 11.25 / 12.5 / 13.75 Mana per 0.25 seconds

COOLDOWN: 3 seconds

CAST TIME: none

RANGE: 750 – 920 (based on level)

Turn rate: 180°/s

Aurelion Sol charges for up to 3.25 seconds to exhale a beam of starfire, during which he can steer the beam in the target direction. The beam collides with the first enemy hit to reveal them and deal magic damage every 0.125 seconds, reduced to 50% for other surrounding enemies hit by the beam. The AOE is a cone shape behind the initial target. Can be recast early to cancel charge.

The beam will deal a burst of % max HP bonus magic damage for each full second that it damages the same enemy, and generates 2 Stardust if the target is a champion. The damage based on the target's health ratio is capped at 300 against monsters.

Breath of Light is locked out for 1 second if the channel is cancelled within the first 0.25 seconds (Q tap).

Breath of light is not a projectile so abilities such as Yasuo's Windwall do not block.

Spell shields block the burst damage but not the beam.


W: Astral Flight

COST: 50 / 55 / 60 / 65 / 70 Mana

COOLDOWN: 22 / 20.5 / 19 / 17.5 / 16

CAST TIME: 0.4

RANGE: 1500 (+ 7.5 × Stardust)

Aurelion Sol flies in the target direction and resets breath of light's cooldown. During flight, he has unobstructed vision and breath of light has no cooldown, maximum channel duration, and its flat damage is increased, but astral flight's speed is reduced by 50% during its channel. Can be recast early to cancel flight.

Earning a champion takedown (kill or assist) within 3 seconds of damaging them reduces astral flight's current cooldown by 90% of its total cooldown.

Aurelion Sol will not fly if he is immobilized or grounded during the cast time. He can cast any of his abilities during the dash. Breath of light's channel will be interrupted if astral flight ends or singularity is cast during the flight, but the ability will automatically be cast afterwards.

Astral flight will be cancelled if Aurelion is immobilised while flying.


E: Singularity

COST: 90 Mana

COOLDOWN: 12 seconds

CAST TIME: 0.2 seconds

TARGET RANGE: 750 – 920 (based on level)

Aurelion Sol spawns a black hole at the target location after a 0.5 second delay that lasts for 5 seconds, granting sight of the area and dealing magic damage every 0.25 seconds to enemies within. Enemies in the black hole are dragged inward until they reach the center, and minions and monsters also have their movement speed reduced to 0. Enemies within the center are executed below 5%(+2.6% Stardust) of their maximum health, excluding epic monsters.

After Singularity ends, it generates 1 Stardust for each full second that enemy champions were inside it, as well as varying amounts for enemy units that were killed while being within the area:

Champions and epic monsters grant 2 Stardust.
Large minions and monsters grant 2 Stardust.
Small minions and monsters grant 1 Stardust.

Singularity will cast at max range if cast within 200 units beyond max range. During astral flight, it will cast at max range if cast at any range beyond.


R: Falling Star

COST: 100 Mana

COOLDOWN: 120 / 110 / 100 seconds

CAST TIME: none

TARGET RANGE: 1250

Aurelion Sol calls down a star that strikes the target location after 1.25 seconds, dealing magic damage to enemies hit and stunning them for 1 second. This generates 5 Stardust for each enemy champion hit.

Aurelion Sol will transform falling star into the skies descend each time he gathers 75 Stardust from the last time he used the empowered cast, or once he has gathered that amount after learning the ability.

Falling Star will cast at max range if cast within 200 units beyond that. During astral flight, it will do so at any range beyond the max.

The Skies Descend:

Aurelion Sol calls down a giant star that strikes the target location after 2 seconds, dealing 25% increased damage in a larger area and knocking up enemies hit for 1 second.

Additionally, the impact sends a massive shockwave that rapidly expands from the area over 3 seconds, dealing magic damage to enemy champions and epic monsters hit, slowing all enemies hit by 50% for 1 second, and revealing them for 1.5 seconds.

The skies descend will cast at max range if cast within 200 units of max range. During astral flight, it will do so at any range beyond the max. Enemies hit by the star are immune to the shockwave.
Mechanics
Q Taps: Aurelion Sol's Q Breath of Light can be tapped (less than 0.25 seconds active) to proc items and runes. This includes Arcane Comet, Scorch, Manaflow Band, Rylai's Crystal Scepter etc. Because of the cone AOE of breath of light champions just behind the wave can still be hit.

W Reset: Champion takedowns (kill or assist) within 3 seconds of damaging them reset Astral Flight. Can be used in teamfights to change flight direction or catch up to low enemies running away. If an enemy is guaranteed to die you can use W, get the takedown during flight and then be guaranteed a reset when flight ends or you recast.

W Through Walls: Direct Astral Flight through walls so you can maintain range for Q but be out of melee range of enemies. Useful for walls like those around drake and baron pit, walls parallel to the river, and walls parallel to lanes.

E + Q: Use E + Q to execute minions to gain stacks. In the early game this is harder because no waveclear, E execute is lower, and Q duration is maxed at 3.25 seconds. After level 9 (Q maxed) this becomes much easier. On cannon waves stand very slightly off centre to the wave and focus on the cannon minion with Q and you should get the whole wave (8 stacks, 6 + 2 for cannon).
Matchups
Section is work in progress. I'm adding the matchups in alphabetical order.

This section is a basic summary on how to play most matchups you will see in midlane. For specific questions on how to play a particular matchup or situation leave a comment in the discussions section.


Ahri

Aggressive rune page recommended as you can trade with Ahri and you outscale. BFT rush usually fine as she can't oneshot you and will let you compete for prio once you have level 9 (maxed Q).

Level 1 Ahri will try to auto you and use her W Fox-Fire to proc electrocute. Unless she is overextending in the wave it's unlikely you win the trade and the movespeed from Fox-Fire lets her outrun your Q Breath of Light. Best to back off.

Try and poke with Q taps. Stack from opposite side of wave.

When you are trying to stack on wave its likely Ahri will walk up to try and charm you. Turn your Q focus to her, she will charm you, then you can chase her down with W maybe get a flash or ult from her.


Akali

Aggressive rune page recommended as you can poke Akali and you outscale. Rylai's rush best as Akali has high all in potential.

Bit of a skill matchup but her early game burst can make a single mistake ruin the lane. Never fight her in her W Twilight Shroud as she gets more energy. Don't try and 1v1 her and focus on getting HP items to stay alive. Zhonya is a good item vs Akali. Like all assassins, Aurelion hard outscales.

Use Q taps with Scorch and Arcane Comet to poke her down.

Aurelion Q and E 'reveal' Akali in her W Twilight Shroud.


Akshan

Defensive rune page with bone plating recommended to survive the early game. Rylai's rush best.

Akshan has a very strong early game and will look to E Heroic Swing on you when you try and Q the wave. Treat the lane the same as Talon and give up some CS early. Akshan needs early game kills to snowball or he will be weak later. Don't give him those early kills and outscale him.

Stand to the side of the wave to avoid his Q Avengerang when he waveclears.

If you play safe successfully and give up cs Akshan will begin to roam so get some control wards down near river and ping your allies if he moves.

Akshan R Comeuppance can be dodged if you stand behind a turret that hasn't been destroyed (or an ally).


Anivia

Stacking rune page good here. BFT/Rylai's/ROA all viable depends on comps and game state.

Good Anivia players will give you a hard time. Both her Q and W (only if she displaces you by placing wall directly under you, otherwise you fly over wall like any other wall) can stop your flight and E (600 units) is nearly as long as Aurelion Q (750 units) early game. Don't try to 1v1 and focus on farming up. Her low kill pressure makes the lane more manageable. Gathering storm a good option just like in other scaling matchups.

Will use Q Flash Frost and W Crystallize to stop you from stacking.


Annie

I would recommend the stacking rune page for lower E CD to stack from a distance without Q. Rylai's rush to avoid getting oneshot.

Difficult laning phase due to her very high burst and Q Disintegrate (625 units) being point and click. Pay attention to her passive stacks to avoid stuns. Baiting her stun makes her vulnerable to ganks. Banshee's Veil can be useful to break up her combo or Zhonya if you are fast enough.


Aurora

Aggressive rune page recommended as you can trade with Aurora and you outscale. BFT or Rylai's fine, I would usually go for Rylai's because Aurora is mobile and has high burst.

Annoying matchup due to her poke but her lack of cc makes her easy to W Q and bait for ganks. Refill pot on first base good here.

Careful using Q as that sets up her hitting her abilities as she is skillshot based and you will get chunked. Cancel Q to dodge.


Azir

Stacking or aggressive rune page depending on comps. Uusually I would go BFT for waveclear and mana.

Annoying matchup due to his poke but his lack of cc makes him easy to W Q and bait for ganks. However, be aware of him ulting you or your jungler under his turret. Take refill pot on first base.

Azir lacks kill pressure early but he can set up ganks with his shuffle. Both Azir and Aurelion scale very well. Probably the best example of a skill matchup for Aurelion.


Brand

I would take stacking runes as I usually find this lane quite uninteractive. BFT probably best to match waveclear.

His early game waveclear and poke will keep you under turret, see if you can get your jungle to gank him. Stand away from the wave so he can't reach you with his E Conflagration. If he uses W E to shove a wave he is vulnerable.

Brand is one of only a few champions that can match Aurelion in terms of late game teamfighting.


Cassiopeia

Stacking runes here, you won't win trades early. Rylai's would be my default but if the Cassio is passive you can get away with BFT.

Difficult lane due to her high range Q Noxious Blast (850 units). She will look to run you down whenever you stand still. Her W Miasma will cancel your W during cast time, otherwise you fly over it. If you ever get a gank, fly at her from the opposite direction of your jungler so she can't ult both you and your jungler.

Uusually I give up prio and let her push wave in because trying to stack the wave out of turret lets her chase you down, unless you can dodge her Q.


Cho'Gath

Stacking runes because lower E CD is needed in this matchup. Probably Rylai's first to avoid getting oneshot.

Movespeed or AP Cho is an equally impossible lane. Both his Q and W cancel Aurelion Q and W. The only way to win is hide under turret and hope you can outscale him because you will melt him after 25 minutes. Avoid using Q for long periods of time or you will lose half your HP to his knock-up into combo.

I recommend tier 1 boots early to help you dodge his Q Rupture.


Corki


Usually I find this to be a farming lane but you can go either stacking or aggressive runes depending on comps. BFT or Rylai's rush.

He can tank your Q when using his E Gatling Gun and win the trade. Focus on farming up and scaling.

No CC so easy to gank or chase down with W Q.


Diana

Aggressive runes because you can poke her down as she is melee. Rylai's needed as she is high burst.

Avoid her Q Crescent Strike poke and you will be fine. Buy HP to reduce her all in potential. If you go equal in lane you win the game because Diana is feast or famine. After level 6 don't use your W till after her ult otherwise she will cancel flight.

Zhonya can be good to avoid her R Moonfall.


Ekko

Aggressive runes best in my opinion for poke. Rylai's mandatory to survive his burst and slow him down.

Really hard lane, almost impossible to trade with Ekko. Hail of blades Ekko with his passive movespeed makes him the Garen of midlane with the non-interactive playstyle. Be respectful and back off if you hear him use W Parallel Convergence. If you don't feel comfortable with the matchup you may want to try a defensive summoner instead of Teleport in this lane such as Barrier.

Be careful with Zhonya against Ekko as it can set up his W or R. Ekko also scales quite well for an assassin making this harder than most assassin matchups.


Fizz

Defensive runes with bone plating. Rylai's rush or even ROA if the comps allow for it.

Probably the hardest lane for Aurelion, defensive summoner instead of TP if you want. Bone plating can reduce his combo damage. Take scorch and try and poke him down in the early levels while he is farming to make him all-in-ing you more risky. Take Zhonya third for if you get by his R so you can completely dodge the damage.

If he uses E Playful / Trickster aggressively before level 6 that is an opportunity for you to use W.


Galio

Stacking runes for max stacks. BFT usually safe here.

The first few levels can be difficult because of his surprisingly high damage and waveclear but he won't be able to kill you at any point. Galio will have one mission all game, shove the wave quick and look to ult to a sidelane. Try and match his waveclear as quick as possible and follow his roams.

After 25 minutes with 300 stacks and either Void Staff or Bloodletter's you will melt him. A good matchup for Gathering Storm as you probably won't interact much.


Heimerdinger

Runes and items depend on comps, I would lean towards stacking rune page.

Annoying early game but you can both move and clear his turrets with your E. Turrets dying in your E count as a passive stack. Let him push and clear the wave under your own turret. You can out roam and outscale Heimer so the matchup isn't too bad.


Hwei

Choose runes depending on team comps. BFT safe here to match waveclear.

Can be annoying early but if he uses Q on you (orange abilities) he has no waveclear. Take a refill pot. If he ever misses fear you can use W Q. Recent nerfs to Hwei have made the matchup a lot easier.


Irelia

Stacking runes here because she will rush Vampiric Scepter and heal through any poke. Rylai's is needed for hp and slow.

Early game is really difficult, must dodge her E Flawless Duet or you will lose half your HP. Getting boots early will help you dodge her E and survive. You will hard outscale.


Jayce

Aggressive runes better here. First item rush depends on comps and how the lane plays out.

Mainly farming lane, but he will look to poke you when you Q. His knock back will cancel your W so try and wait that out before flying. If he is in melee form hold your ground and use Q, he will cancel it with knock back, and then you are free to chase him down with W Q.


Kassadin

Stack maxing rune page. Rylai's better for HP and slow.

Non-interactive lane, both champs looking to scale with minimal damage early. He does have a silence so he can cancel your Q. Don't try and 1v1 after level 6. Take gathering storm and scale up. Poke him down before level 6 when he goes for cs with Q and autos.


Katarina

Aggressive runes for poke and trading. Rylai's need for HP and slow.

Highly mobile assassin with high burst makes the lane difficult. Never try to 1v1 and stack HP early to survive. If she is perma roaming you will want to get fated ashes to shove waves and get vision around midlane river, usually botside. Do your best to reduce her map impact and you will outscale.
Lane Phase and Early Game
The early game for Aurelion Sol is all about being patient. You must respect your weak early game.

Grab your Doran's Ring and Health Potion and head to midlane. Before minions spawn your role is to help get vision of the enemy jungle. Carefully, see if you can get a Stealth Ward down at the enemy raptor camp around 1:20-1:25 into the game. This ward will stay alive long enough for you to get vision on the enemy jungle. Once the enemy jungle is spotted at the raptor camp, press tab to check their creep score. 8 CS mean they started at red buff, 12 means they started at blue buff and full cleared that side of their jungle. You can use this knowledge to work out which direction they are clearing. This is known as jungle tracking. Position in lane away from the side of the map the enemy jungle is in to reduce the chances of getting ganked. At 3:30 the junglers will have finished their clears, taken rift scuttler and will be looking to gank, so be aware of this when trading and hitting minions.

For your first recall there are a few gold amounts to reset with:

400g = Dark Seal + Health Potion or Amplifying Tome or Ruby Crystal

500g = Dark Seal + Refillable Potion

700g = Amplifying Tome + Sapphire Crystal or Ruby Crystal + Sapphire Crystal

850g = Blasting Wand

900g = Fated Ashes

1200g = Lost Chapter or Fated Ashes + Sapphire Crystal

1300g = Catalyst of Aeons

Your first buy is dependent on the lane matchup and the first item you are going for. Dark Seal is a very gold efficient item that can quickly become powerful after a few stacks. If you fall behind and can't get stacks it sells for 140g so only 210g is lost. The risk is low but the item should be treated like a starter item so you should keep it in your inventory until you need the gold or item slot. I don't recommend upgrading to Mejai's Soulstealer as Aurelion Sol is a vulnerable champ but it depends on the game and your playstyle.

If the lane is rough focus on getting HP and Refillable Potion. Boots can also be a useful choice against some matchups like Zoe and Yone.

For the higher ranks try and time your recalls so you are back in lane with HP and mana ready for fights at objective spawns. The first drake spawns at 5:00 and voidgrub spawn at 8:00. Remember you are weak early so giving objectives can be a good option if your team is not ahead.
Mid Game
In the mid game your main job is to push sidelanes and be ready for objectives. The bot lanes will move to mid lane usually after an outer turret is taken bot. Astral Flight becomes a powerful ability at this stage of the game as you can look for catches using Rylai's Crystal Scepter and Falling Star.

Try and stack up and get your empowered ult ready for big objective fights like atakhan and drake

Once you have completed two items, around 18 to 20 minutes into the game, you spike hard and become a useful asset for your team. Before this spike be cautious and play safe.
Late game / Teamfighting
This is where the fun begins.

At 25 minutes you should be at, or approaching, 300 stacks on Cosmic Creator and your third item.

Continue to push sidelanes; if you have Teleport make sure you're pushing on the opposite side of the map of the upcoming objective unless your toplaner is doing that for you.

In teamfights you should be aiming to combo on the highest priority enemy. This is usually whoever is doing the most damage, most likely the adc or midlaner, but it could also be a carry champ in another role such as Viego jungle or Kayle top.

The alternative is using Falling Star for peel or zoning. For example if your adc is a fed Caitlyn and the enemy has a Vi looking to use her ult Cease and Desist, you can ult Vi as she finishes her ult animation to help keep Caitlyn alive or you can ult the rest of the enemy team as they try to follow up the Vi ult.

Use your Astral Flight resets after takedowns to keep flying inbetween kills but be careful to not fly into danger.
Outro
I hope this guide is a useful tool for anyone that wants to play Aurelion Sol. I've stuck mainly to topics that specifically impact Aurelion rather than things such as macro because this is an Aurelion guide rather than a mid lane guide but I may add information in the future.

If you found the guide useful please leave a thumbs up as that helps the guide get recognition.

If you have a suggestion for the guide or see any type of error please let me know in the comments!

Have fun on the Rift and good luck with your climbs!
Logs/Patch History
[25.11] Added sections for Abilities, Mechanics, and Matchups. No changes in this patch that effect Aurelion, Horizon Focus still unlikely to be any good.

[25.10] Made some big changes to recommended runes and builds. Precision secondary rather than inspiration.

Bloodletter's buff feels good and Aurelion is already argueably the best user of the item out of any champ. I think this item is strong enough to be built every game. I'll keep an eye on data but it might be good enough for second item after Rylais.

[25.09] Spirit Blossom - Rod of Ages nerf will reduce the priority of the item but I think it will still be ok for difficult or scaling lanes. If the nerfs to biscuits are big I think the precision tree for secondary runes might become a lot more popular. Void grubbs spawn later and only once which is nice for Aurelion in his weak early game. Symbiotic Soles nerf means they no longer give empowered recall so I think these will be basically useless for non-supports, unlikely to be good for Aurelion anymore.

After trying ROA on patch 25.09 it feels ok but nothing special. If you play in diamond+ I only recommend ROA if the matchup and comps specifically fit a ROA situation.

[25.08] - Cryptbloom buff unlikely to make the item any better on Aurelion because he doesn't really need Ability Haste. Void Staff and Bloodletter's Curse still the better options for magic pen.
