Anaxa is a powerful Wind Erudition unit inHonkai: Star Rail, bringing a unique blend of AoE damage and utility to the battlefield. His standout mechanic lies in his ability to implant weaknesses into enemies, which is quite useful toreduce their toughnessand enable him to ignore their DEF based on the implanted weaknesses. His ascension trace is also quite unique, allowing players to choose to utilize him either as a Hypercarry sole Erudition character in the team, or otherwise as a sub-DPS with another Erudition character like The Herta as the number of Erudition characters will essentially decide whether Anaxa gets a Crit DMG buff or otherwise a team-wide DMG buff.
This means, when it comes to light cones, Anaxa’s optimal choices will vary slightly depending on his role as either ahypercarry or a sub-DPS. In hypercarry setups, light cones that enhance his personal damage are prioritized to maximize his impact as the sole Erudition character. In sub-DPS roles, his focus shifts slightly to support team synergy. Regardless of the role however, the top 3 choices for Anaxa’s best light cones inHonkai: Star Railwill be the same, as they fit Anaxa’s kit very well. Luckily, players should have access to a good blend of premium and F2P options to choose from.
Anaxa benefits from light cones that provide Crit, ATK% and DMG increase specifically, while Energy Regeneration or Speed could also come in handy as added bonuses depending on the rest of the effects.

For every enemy on the field, increases the wearer’s ATK by9%, up to 5 stacks. When an enemy is inflicted with Weakness Break, the DMG dealt by the wearer increases by30%for 1 turn.
Night on the Milky Waystands outas a solid light cone optionfor Anaxa, especially in his sub-DPS role. Its ability to increase his ATK by up to 45% when there are five or more enemies makes it exceptionally valuable in scenarios with large enemy groups. Additionally, it provides a further DMG boost whenever an enemy is inflicted with Weakness Break. Given Anaxa’s ability to implant weaknesses regardless of the enemy’s original weakness, this effect is generally reliable and synergistic with his mechanics.
However, the light cone’s second effect makes it better suited for sub-DPS setups rather than hypercarry compositions. In hypercarry builds, Anaxa often pairs withallies like Robin or Sunday, who typically target him instead of attacking enemies directly, reducing the consistency of the DMG boost from Weakness Breaks. Fortunately, the condition only requires one enemy to be inflicted with Weakness Break, ensuring the light cone remains effective in most scenarios. This makes Night on the Milky Way an outstanding choice for content like Pure Fiction, where battles often involve numerous weaker enemies alongside a single elite or boss, leveraging its full potential.

Increases the wearer’s ATK by12%. After using an attack, for each enemy target hit, additionally increases ATK by8%. This effect can stack 5 times and lasts until the next attack. If there are3or more enemy targets hit, this unit’s SPD increases by16%, lasting for1turn(s).
As a solid F2P alternative,Eternal Calculusis a strong choice for Anaxa. While it may fall behind Night on the Milky Way when facing five or more enemies, Eternal Calculus doesn’t rely on enemy count to perform effectively. Thanks to Anaxa’s bounce ability, this light cone can consistently stack ATK—even with fewer targets—reaching a comparable 52% ATK at max superimposition. Additionally, it provides a SPD boost if more than three enemies are hit, helping Anaxa reach critical SPD breakpoints and improving his rotations in combat.
What sets Eternal Calculus apart is its versatility. It doesn’t depend on Weakness Break effects or specific enemy numbers, making it more reliable inchallenging content like Apocalyptic Shadowor Memory of Chaos. These scenarios often involve enemies with high toughness, making Weakness Breaks harder to achieve. With its consistent effects, Eternal Calculus ensures Anaxa remains valuable across various battle conditions. Nevertheless, compared to other options, it’s not going to allow Anaxa to perform with utmost synergy with his kit, making it a better option for sub-DPS Anaxa team setups over Hypercarry variants.

After entering battle, increases the wearer’s DMG based on their Max Energy. DMG increases by0.4%per point of Energy, up to160Energy.
WhileToday is Another Peaceful Dayis a Battle Pass-exclusive light cone and thus not F2P-friendly, it stands out as an excellent low-budget option for Anaxa in particular for hypercarry setups. Anaxa’s Ultimate cost is capped at 140, which, while lower than some Erudition characters, is still sufficient for him to receive a significant DMG boost. At max superimposition, this light cone can even outperform the previous options discussed and many premium 5-star Erudition Light Cones tailored for Anaxa. Its generalist effect and scalability make it a strong contender for players willing to invest in it through the Battle Pass.

Increases the wearer’s ATK by16%. For every 1 different Weakness Type an enemy target has, increases the DMG dealt to it by the wearer by8%. Up to a max of 7 Weakness Types can be taken into account for this effect.
TheGreat Cosmic Enterpriseis a highly effective F2P-friendly light cone designed with Anaxa in mind. Its core benefits include boosting ATK%, which aligns perfectly with Anaxa’s need for additional ATK to maximize his damage potential, given that his kit lacks natural ATK scaling. Additionally, it provides a significant DMG boost based on the number of weaknesses present on enemies, making it particularly powerful since it synergizes with Anaxa’s ability to implant weaknesses consistently.
What sets this Light Cone apart is its reliability across various team compositions and scenarios. Unlike some other options, The Great Cosmic Enterprise maintains consistent value regardless of whether Anaxa is used as a hypercarry or a sub-DPS. While it doesn’t reach the same heights as his signature Light Cone, it offers exceptional utility and performance for budget-conscious players. For those who acquired it through the HSR Second Anniversary Event and fully superimposed it, this light cone serves as an excellent and dependable alternative to its premium counterparts.

Increases the wearer’s CRIT Rate by12%. When the wearer uses their Ultimate, increases DMG dealt by the wearer’s Skill and Ultimate by60%, lasting for3turn(s). After the wearer uses their Ultimate, if this Ultimate consumed 140 or more Energy, recovers1Skill Point.
Into the Unreachable Veilis a strong premium light cone option for Anaxa, offering added Crit Rate stat and Skill DMG boost. Designed asThe Herta’s signature light cone, it features one of the highest base ATK value for an Erudition light cone, which makes it quite useful for Anaxa as well. Furthermore, since Anaxa’s Ultimate cost is at 140 Energy, he can also benefit from being able to recover a skill point, making it particularly valuable in team comps that require heavy skill point requirements.
It is worth noting that this light cone, similar to The Great Cosmic Enterprise and Anaxa’s signature light cone, performs exceptionally well regardless of whether he is utilized as a sub-DPS or hypercarry. However, for dual-DPS compositions featuring The Herta, players may choose to equip Into the Unreachable Veil on her instead, as its effects align seamlessly with her kit. Nevertheless, Anaxa can still fully leverage its benefits, making it a versatile option that avoids overly complicated build optimizations. Furthermore, Into the Unreachable Veil is considered more generic compared to Anaxa’s signature light cone, offering broader utility for players who prefer investing in flexible, future-proof options rather than niche picks tailored to specific characters.
When the wearer’s turn starts, regenerates 10 Energy. If the enemy target has a Weakness implanted by the wearer, increases the wearer’s DMG dealt to it by 60%. When an enemy target gets attacked by the wearer, the wearer decreases the target’s DEF by 12%, lasting for 2 turn(s). The same types of effects cannot stack.
Life Should Be Cast to Flames, Anaxa’s signature light cone, is undeniably his best option regardless of whether he is utilized as a hypercarry or a sub-DPS. Specifically tailored for his mechanics, this Light Cone offers unmatched synergy with his ability to implant weaknesses and capitalize on them. Its effects regenerate energy for Anaxa, ensuring consistent uptime of his Ultimate, while simultaneously boosting DMG against enemies with weaknesses applied directly by him. Additionally, it decreases the DEF of targets, further amplifying his damage potential and benefiting the entire team.
While its effects are highly specific to Anaxa’s playstyle, this light cone’s team utility—through its DEF reduction—ensures that it remains a valuable choice in any composition. However, it’s worth noting that the light cone’s utility is limited for other Erudition characters, as few can naturally implant weaknesses on their own to fully activate its potential. Additionally, unlike some characters who heavily rely on their signature light cones to function optimally—such as Boothill or Acheron—Anaxa remains less dependent on this particular option. This means, while Life Should Be Cast to Flames elevates his damage and team utility, Anaxa can still deal significant damage with alternative light cones. Its value lies in optimizing and amplifying his existing strengths rather than transforming his overall playstyle, making it a top choice but not an absolute requirement for strong performance.
