- Triggers Aha state for entire team
- Grants All-Type RES PEN (up to 20% at max level)
- Allies immediately take action (100% action advance)

Punchline Generation (Talent)
- Generates Punchline stacks through Basic ATK and Skill
- Shared team resource that boosts Elation DMG
- Critical for Elation DPS like Sparxie

Elation Core Team (Best)
Sparxie + Yao Guang + Sparkle + Hyacine/Fu Xuan
- Sparxie: Main Elation DPS with Punchline scaling
- Yao Guang: Elation support & Punchline generator
- Sparkle: SP recovery + CRIT DMG sharing
- Hyacine: Remembrance healer with energy support (3.3) OR Fu Xuan for current sustain
Pre-Sparxie Team
Yao Guang + Sparkle + Any DPS + Sustain
- Works with SP-hungry DPS until you get Sparxie
- Yao Guang's buffs are still valuable universally
Budget Team
Yao Guang + Any DPS + Asta/March 7th Hunt + Natasha
- 4-star friendly composition
- Shows her core mechanics before investing
Trace Priority
| Priority | Trace | Reason |
|---|---|---|
| 1 | Skill | Zone deployment - core ability |
| 2 | Ultimate | Aha Instant + RES PEN buff |
| 3 | Talent | Punchline generation + Elation buffs |

Gameplay Tips
- Speed Threshold: Hit 160 SPD for full Diviner of Distant Reach bonus
- Ultimate Timing: Use Ultimate when allies are ready to burst (100% action advance is massive)
- Zone Management: Skill lasts 3 turns - manage SP efficiently
- Party Position: Don't place Yao Guang first (Lushaka buff goes to first character)
- Punchline Focus: Prioritize generating Punchlines for Elation DPS
- Energy Management: Need 160%+ ER for consistent Ultimate cycles
Eidolon Analysis
| Eidolon | Value | Effect |
|---|---|---|
| E0 | ★★★★★ | Complete kit, fully functional |
| E1 | ★★★★★ | Best stopping point. Doubles Punchline on Aha turn + Elation DMG ignores DEF |
| E2 | ★★★★ | More SPD + Elation buffs during Zone |
| E4 | ★★★ | Energy regen when allies attack in Zone |
| E6 | ★★★★★ | Massive Elation scaling boost |
Verdict: E0 is excellent. E1 is a game-changer if you're investing in Elation teams.

Summary
Yao Guang is essential for Elation teams and marks the debut of a new viable team archetype in HSR 4.0. Her kit revolves around Speed scaling, Zone deployment, and enabling burst windows through Aha Instant. While she's specialized for Elation, her RES PEN and action advance provide universal value.
