Yao Guang Best Light Cone | HSR 4.0

With Yao Guang stepping into Honkai Star Rail as a brand-new 5★ Elation character, her Light Cone quickly becomes one of the most important pieces to understand. Whether you’re aiming to maximize her speed scaling, boost team-wide Elation damage, or push AHA Instant to its limit, choosing the right Light Cone can make or break her performance.

In this guide, we’ll break down Yao Guang’s best Light Cone options, from her signature pick to strong 4★ and budget-friendly alternatives.

Best Choice

When She Decided to See

Game Changer

Increases the wearer's SPD by 18%. When the wearer enters combat or uses Ultimate on an ally target, the wearer gains "Great Fortune" for 3 turn(s). While the wearer has "Great Fortune," all allies' CRIT Rate increases by 10%, CRIT DMG increases by 30%, and the wearer's Energy Regeneration Rate increases by 12%.

At the start of each wave, the wearer regenerates a fixed amount of 15 Energy.

This Light Cone is perfectly suited for Yao Guang as it directly amplifies her core role as a fast-paced Elation buffer and team enabler. The 18% SPD boost allows her to act more frequently, building Elation stacks faster to maintain consistent uptime on her supportive Zone. Furthermore, the "Great Fortune" effect provides crucial team-wide CRIT Rate and CRIT DMG buffs, which significantly enhance the damage output of her allies' follow-up attacks— a cornerstone of Elation team synergy. Finally, the Energy Regeneration and flat Energy gain ensure she can cast her Ultimate regularly, keeping her buffs active and the team's momentum high.

 

Alternatives

Center of Attention

Increases the wearer's CRIT DMG by 48%. While the wearer is on the field, for every Elation character on the team, increases the Skill Point upper limit by 1, up to a max increase of 3. For every 1 Skill Point the wearer consumes, ignores 5% of enemy targets' DEF when this unit deals Elation DMG, stacking up to 4 times. If 4 or more Skill Points are consumed in the same turn, the wearer gains "Stream Promo," which increases all allies' Elation by 20%. Light Cone effects of the same type cannot stack.

It is ideal for Yao Guang because it supercharges her Elation-based support and damage amplification while solving her team’s SP economy issues. The 48% CRIT DMG boost directly enhances her own damage and strengthens her role as a sub-DPS, while the SP upper limit increase (up to +3) is a game-changer for Elation teams that rely on frequent Skill usage to trigger follow-up attacks. Additionally, the DEF ignore from consuming SP synergizes perfectly with her playstyle of spamming Skills to maintain Elation stacks and buff uptime, and the "Stream Promo" effect provides valuable Elation gain for the entire team, further boosting their follow-up damage potential.

Decision

Increases the wearer's CRIT Rate by 12%. When the wearer uses an Elation Skill, increases Elation by 12%, stacking up to 2 times.

It is a strong fit for Yao Guang because it directly enhances her Elation generation and consistency, two of her core strengths. The 12% CRIT Rate boost improves her reliability as a sub-DPS, while the Elation gain from using her Skill helps her reach the crucial Punchline thresholds faster, ensuring her supportive Zone and powerful follow-up attacks are triggered more frequently to keep the team’s momentum high.

Mushy Shroomy's Adventures

Rumble

Increases the wearer's Elation by 12%. When the wearer uses an Elation Skill, increases Elation DMG taken by all enemies by 6% for 2 turn(s).

It is a solid choice for Yao Guang because it directly boosts her Elation stat to strengthen her supportive Zone effects and increases the Elation DMG taken by enemies, which significantly amplifies the follow-up damage of her entire team—aligning perfectly with her role as an Elation enabler.

Sneering

Indulgence

When Aha Instant is activated, the wearer's Elation increases by 16%, lasting until Aha Instant ends.

It is well-suited for Yao Guang because it provides a substantial 16% Elation boost precisely when she activates Aha Instant, which is likely a key part of her ultimate or burst rotation. This temporary surge in Elation significantly enhances the power of her Zone, buffs, and follow-up attacks during critical moments, making her a more potent enabler for the team exactly when they need it most.

Lingering Tears

⭐️⭐️⭐️	847	318	265

Mourning

When Punchline is 10 or more, the wearer's CRIT DMG increases by 20%.

It is a strong choice for Yao Guang because it rewards her natural playstyle of building high Punchline stacks through frequent Skill usage and fast turns. Since she excels at maintaining high Elation and Punchline counts to sustain her Zone and buffs, the 20% CRIT DMG boost activates reliably, significantly increasing her sub-DPS output and making her a more consistent damage dealer in Elation teams.

 

Conclusion

Overall, Yao Guang’s signature Light Cone offers incredible value thanks to its speed, energy regeneration, and powerful team-wide buffs, making it the best choice for players investing in the Elation playstyle. That said, solid 4★ and even 3★ options can still perform well if you’re planning around future Elation teammates.
