Her kit revolves around deploying a Zone that shares her Elation stat with allies, generating Punchline stacks for Aha's Instant (an extra team turn with massive Physical Elation DMG), and providing 10-20% All-Type RES PEN via her Ultimate. She excels at enabling SP-hungry DPS like Sparxie or Archer by triggering additional Elation DMG procs on every ally attack (doubled if SP is consumed), while her traces offer up to 60% CRIT DMG, SP recovery, and massive Elation scaling from SPD (up to 110% bonus at 200+ SPD).

With her banner live alongside Sparxie in Phase 1, players face a classic dilemma: pull her signature Light Cone (When She Decided to See) for S1, or chase E1 on her character banner? Both upgrades shine in her role as an Elation amplifier, but their value depends on your resources, team comps, and playstyle. Let's break it down.

Yao Guang's Signature Light Cone: When She Decided to See (S1 Breakdown)

This limited 5-star Elation LC is tailored for Yao Guang's high-SPD, energy-hungry rotations:

EffectS1 ValueImpact
SPD Boost+18%Pushes her base 101 SPD toward key breakpoints (160-200 SPD for max Elation via A2 trace and Diviner 4pc). +18% actions = faster Punchline gen and Zone uptime.
Great Fortune (3 turns on entry/Ult)Team +10% CRIT Rate, +30% CRIT DMG, +12% ERRSynergizes with her RES PEN; triples value in multi-DPS teams. Covers her CRIT needs without relic RNG.
Wave Start+15 EnergyCovers ~8% of her 180-cost Ult, enabling 1 extra Aha Instant per 3-min fight (e.g., 4 vs. 3 in MoC).

Pros: QoL king for any team. 25-30% total performance uplift over top 4-stars like Mushy Shroomy's Adventures S5 or Today's Good Luck S5, via more Aha cycles and team CRIT. F2P-friendly alternatives close the gap to ~70-75% in short fights, but sig pulls ahead in prolonged content like Apocalyptic Shadow.

Cons: Not essential; strong 4-stars provide similar Elation/CRIT. Less "burst" than E1.

E1: Chuckle Chimes Where Jade Falls (Breakdown)

E1 supercharges her core Ultimate loop:

EffectValueImpact
Aha Instant Punchline40 fixed (vs. base 20)Doubles the instant's DMG/stacks (~100% uplift on this burst turn). Stored for 2 turns, ramps team output massively.
Elation DMGIgnores 20% enemy DEFUniversal multiplier on all Zone Elation hits (procs, Skills, Aha). Stacks multiplicatively with RES PEN/vuln; shines in Elation hypercarry.

Pros: Labeled "amazing/best stopping point" across guides. Transforms her from great to broken in Sparxie teams, where every Elation proc matters. DEF ignore is rarer and stronger than CRIT (especially vs. high-DEF bosses). Pairs perfectly with E4 (1.5x Elation Skills on Aha) for absurd bursts.

Cons: Slightly niche to Elation comps; less versatile than sig's SPD/CRIT/energy for generalist Archer teams.

Head-to-Head: Sig LC (E0S1) vs. E1 (E1S0)

No universal calc sheet pins an exact %, as it varies by content/team (e.g., MoC favors bursts, PF waves favor energy). However:

ScenarioWinnerWhy (Est. Uplift)
Elation Hypercarry (Sparxie + Sparkle)E1 > S1Doubled Aha Punchline + 20% DEF ignore = 50-100%+ burst spike per Ult cycle. Sig's CRIT is nice, but E1 multiplies core kit directly. Calcs "misleading" outside this archetype.
Generalist/SP Spam (Archer/IL)S1 ≈ E1Sig's SPD/energy/CRIT enables consistent procs; E1's DEF ignore helps but less than in pure Elation. ~25% sig edge over 4-stars, E1 ~20-30% via ignores.
F2P/BudgetE14-stars like Mushy suffice (70-75% sig perf); E1 is "free" damage amp on base kit.
Whale (Both)E1 then S1E1 unlocks potential; sig polishes rotations.

Key Stat: Sig enables ~33% more Aha Instants via SPD/energy (25% stage DMG), but E1 doubles each one's power. In Elation meta (4.0's focus), E1 edges out by 10-20% overall DPS amp.

Pull Advice

  • Prioritize E1 if building Sparxie/Elation: It's her best single upgrade, future-proofing for E6 (+25% team Elation DMG). Skip sig if 4-stars overlaid.
  • Go S1 first for flex teams or if you lack SPD relics/energy: QoL > raw power for consistency.
  • F2P/Skippers: E0S0 clears content fine with Mushy S5 + Diviner 4pc (160+ SPD, CRIT DMG body, ERR rope). Save for Sparxie E0S1.
Verdict: E1 is worth getting over the Light Cone. It amplifies Yao Guang's identity as an Elation enabler, delivering bigger meta impact in 4.0's Sparxie era. Pair her with Sparkle, Permansor sustain, and your favorite SP-drainer for top clears. Happy pulling, Trailblazers!
