Aurelion Sol is universally recognized as the strongest champion in the game, capable of trivializing the hardest content. While his overwhelming power is highly effective, some players find his gameplay repetitive or lacking in challenge.
The Star Forger
  • Starforged Gauntlets icon
    Provides a crucial +1 starting mana, accelerating Aurelion Sol's deployment.
  • Perfect Hex Core icon
    Generates a 0-cost created spell every round, rapidly discounting Aurelion Sol's cost.
  • Disciple of Shadows icon
    Allows Aurelion Sol to be played significantly earlier by sacrificing early board presence.

Strategy

This is the definitive Best-in-Slot build for Aurelion Sol, designed to consistently deploy him on Turn 1 or 2. Starforged Gauntlets provides essential mana acceleration. Perfect Hex Core ensures a steady stream of created cards to trigger his cost reduction. Disciple of Shadows capitalizes on early unit generation to cheat Aurelion Sol out, leading to an immediate level-up and overwhelming board control.
Cosmic Symphony

Strategy

This build focuses heavily on generating created cards to rapidly discount Aurelion Sol and other champions. By flooding your hand with 0-cost spells and conjured units, you can easily overwhelm the opponent. This setup is particularly effective for players who prefer a spell-heavy, value-generating playstyle over sacrificing units.
Celestial Vanguard
  • The Deceiver's Crest icon
    Creates a 0-cost copy of The Skies Descend upon level-up for a massive board wipe.
  • Crownguard Inheritance icon
    Grants a Rally effect when Aurelion Sol levels up, enabling immediate lethal attacks.
  • Z-Drive Prototype icon
    Provides extra rerolls to secure crucial powers like Counterfeit Copies.

Strategy

A highly effective build utilizing only rare and common relics. The core synergy revolves around Aurelion Sol's instant level-up upon being played. The Deceiver's Crest provides a free board wipe, while Crownguard Inheritance allows you to immediately attack with your newly buffed board. Z-Drive Prototype is used to aggressively mulligan for powers that generate cheap created cards.
Other Relic Options
  • The Beast Within icon
    Provides Overwhelm and bonus stats, serving as an excellent alternative win condition if Aurelion Sol is not drawn.
  • Stalker's Blade icon
    Offers immediate board impact and removal upon summoning Aurelion Sol.
  • Guardian's Trinket icon
    Considered a trap relic. It dilutes your deck with random champions, significantly reducing the consistency of drawing Aurelion Sol.
  • Oath of the Guardians icon
    Considered a trap relic. It clogs your hand and deck with champions that do not help accelerate Aurelion Sol's deployment.
Constellation
Aurelion Sol features a unique progression system, capping at 4 stars and requiring specific fragments obtained exclusively from the Glory Store (Monthly Challenges). Despite lacking a 6-star constellation, his base kit and 4-star power make him arguably the strongest champion in the game, capable of outperforming fully maxed 6-star champions.
  • Icon for Astral Radiance

    Astral Radiance

    When you play a created card, reduce the cost of allied champions everywhere by 1. When you play a champion, level them up. You're welcome.
    Review
    Aurelion Sol struggles significantly at 1 star due to starting with only 1 mana, making his high-cost deck feel sluggish and vulnerable to early aggression.
  • Icon for Cosmic Creator

    Cosmic Creator

    +1 Starting Mana. I graciously bestow a Rare or Epic item upon all your created cards.
    Review
    Provides a crucial power spike. Granting random items to created cards significantly enhances the value of his generated Celestials and spells.
  • Icon for Astral Radiance II

    Astral Radiance II

    When you play a created card, reduce the cost of allied champions everywhere by 2. When you play a champion, level them up. You're welcome.
    Review
    The turning point where Aurelion Sol becomes a dominant force. The increased cost reduction and stat buffs allow him to reliably clear the hardest content in the game.
  • Icon for Breath of Light

    Breath of Light

    When you play a unit, double it stats. If it's Aurelion Sol, The Skies Descend upon all your pathetic enemies.
    Review
    An overwhelming upgrade that doubles the stats of all allies. This power effectively functions as a 6-star ability, trivializing even the most difficult Nightmare adventures.
Gameplay Tips
  • Prioritize Created Cards
Focus heavily on acquiring powers and items that generate cheap, created cards (e.g., Counterfeit Copies, Bouncing Blades). These are essential for rapidly discounting Aurelion Sol's cost and deploying him early.
  • Maintain Deck Consistency
Avoid drafting too many additional champions during your run. Aurelion Sol is your primary win condition, and diluting your deck reduces the chances of drawing him when needed. Support champions like Katarina or Viktor, who generate cheap tokens, are the best exceptions.
  • Trim the Fat
Actively look to cut the 3-cost Dragon (Whiteflame) and other slow, high-cost cards from your starting deck at healer nodes to improve your early game consistency.
  • Overriding Cost Modifiers
Aurelion Sol's Level 2 power, which reduces the cost of Celestial cards to 0, overrides negative adventure modifiers like 'Created cards cost more'. This makes him exceptionally resilient against specific Nightmare mutators.
  • Beware of Full Boards
Be cautious when using effects that summon units if your board is full. If Aurelion Sol initiates a free attack while the board is full, he may be obliterated due to a lack of space.
