Yao Guang Character Overview

Yao Guang is a 5-star Physical Elation who serves as the support Elation-based team compositions. Her Skill deploys a Zone for 3 turns that increases all allies' Elation by an amount equal to 20% of her own Elation stat. While the Zone is active, Yao Guang gains 3 Punchline points after using Basic ATK or Skill. Punchline is a team-shared resource that determines the potency of Elation Damage - the more Punchline accumulated, the higher the Elation DMG output. Her Ultimate, grants 5 Punchline points and triggers an immediate extra turn for Aha where a fixed amount of 20 Punchlines is calculated. This turn doesn't consume Punchlines and increases all allies' All-Type RES PEN by 20% for 3 turns.

Her combat abilities center around the "Certified Banger" state obtained through Aha Instant mechanics. When Yao Guang possesses "Certified Banger," allies trigger the "Great Boon" effect after attacking, dealing additional Elation DMG equal to 20% to a random target. If allies consume Skill Points during their attack, additonally triggers Great Boon by 1 time.

Yao Guang's passive traces provide significant team-wide value. Her A2 Trace (Amaze-In Grace) grants increased Elation based on SPD, if her SPD is 120 or higher, she gains 30% Elation, with an additional 1% Elation for every 1 point of SPD above 120, capped at 200 SPD (80% bonus Elation). This makes SPD a critical scaling stat.

Yao Guang Trace Priority

Yao Guang Best Light Cones

1. 5-Star Options

Yao Guang's signature Light Cone is When She Decided To See which provides the following effects at S1:

• SPD scaling that directly converts to more Elation via her A2 Trace
• Team-wide CRIT Rate and CRIT DMG buffs (50 CV total)
• Energy Regeneration to reach Ultimate faster
• Flat Energy per wave for consistent Ultimate access

2. Alternative & F2P Options

Currently, Yao Guang's best 4-star option is Mushy Shroomy's Adventures as it provides both personal Elation% and team-wide Elation vulnerability. The debuff applies immediately when using her Elation Skill, creating strong damage windows. However, it lacks the SPD and Energy Regeneration benefits of her signature.

Yao Guang Relics, Ornaments & Stats Priority

1. Relics

Diviner of Distant Reach (4pc) is Yao Guang's best-in-slot relic set as it also provides her personal damage and her Elation scaling. Combined with SPD boots and substats, reaching this threshold enables optimal performance.

2. Planar Ornaments

Lushaka, the Sunken Seas is her best-in-slot options by providing +5% Energy Regeneration Rate and 12% ATK of the first character in the lineup. While Sprightly Vonwacq provides 5% Energy Regeneration and 40% Advance Forward upon entering battle which might help in some rotations where you would need to use her Ultimate before certain action.

3. Stats Priority

Yao Guang Team Compositions

As the first Elation Path support, Yao Guang works exclusively in Elation-focused teams. Her kit is designed to enable Elation DPS characters through Zone deployment, Punchline generation, and Aha Instant triggers. While she can technically function in non-Elation teams, her value drops significantly as most of her mechanics specifically benefit Elation characters.

Sparxie: 5-star Fire Elation DPS whose damage scales through Punchline accumulation and Engagement Farming. During Aha Instant, she unleashes multi-hit Fire Elation DMG as the team's core burst damage dealer.

Yao Guang: Deploys her Zone to boost team Elation, generates Punchlines through Basic ATKs and Skills, and triggers Aha Instant with Ultimate for massive burst windows. Provides 20% All-Type RES PEN team-wide.

Sparkle: Provides CRIT DMG buffs, 50% action advance, and recovers 6 SP with Ultimate to fuel Sparxie's high Skill Point consumption. Essential for maintaining SP economy while maximizing damage output.

Sustain: Dan Heng Permansor Terrae (DHPT) provides both sustain and additional damage. Huohuo provides Energy which translates to frequent Aha-Instant, SP recovery, and Punchline generation. Gallagher provides consistent SP and sustain.

Yao Guang Eidolons

Eidolon 1

Yao Guang E1 increases the fixed Punchline amount in her Ultimate from 20 to 40, doubling the effectiveness of Aha's triggered turn. Additionally, it provides Elation DMG dealt by all allies to ignore 20% of the target's DEF while the Zone is active.

This is Yao Guang's most impactful Eidolon for players planning vertical investment. The 20% DEF ignore is a universal damage multiplier that benefits all Elation damage sources, and doubling the Ultimate's Punchline calculation significantly amplifies burst damage during Aha Instants.

Eidolon 2

Yao Guang E2 increases all ally targets' SPD by 12% and additionally increases Elation by 16% while the Zone is active.

This Eidolon provides both offensive and utility benefits. The SPD buff directly translates to Aha's Speed via Yao Guang's mechanics, leading to more frequent Aha Instants. The 16% Elation increase provides a meaningful damage boost to all Elation characters. While valuable, its impact is more dependent on specific Speed thresholds compared to E1's universal damage amplification.

Eidolon 4

InAha's extra turn triggered by Yao Guang's Ultimate, the DMG dealt by all ally characters' Elation Skill becomes 150% of the original DMG.

Unlike most E4s which are minimal upgrades, this Eidolon provides meaningful value. The 50% damage increase to all ally characters' Elation Skill during Aha Instant is substantial when paired with DPS whose primary damage comes from Elation Skills.

Eidolon 6

Conclusion

Yao Guang is the 5-star Physical Elation support that servers as the backbone for Punchline-focused teams. Her value lies in maintaining high Zone uptime to amplify allies' Elation stats while timing her Ultimate to trigger devastating Aha Instants with All-Type RES PEN. Prioritize reaching 160+ SPD to maximize her passive scaling, and equip her with Diviner of Distant Reach to ensure your Elation DPS characters like Sparxie can reach their absolute damage ceilings.
