Yao Guang — Honkai Star Rail Character Guide

Overview

First of the Elation Path, providing teamwide RES PEN, DMG Vulnerability, and free Aha Instants via Ultimate. Scales up dramatically with more Elation teammates but offers solid general utility even without them.

Elation Path support who deploys a Zone sharing her Elation stat with the team, generates Punchline consistently via Basic ATK and Skill, and triggers free Aha Instants via Ultimate. Her Certified Banger state enables Great Boon — extra Elation DMG procs on every ally attack, doubled when the attack consumes SP. Manages a 180-Energy Ultimate cycle fueled by a 30-Energy Basic ATK and Energy Regen investment, then delivers teamwide All-Type RES PEN and a free Aha Instant with fixed Punchline that does not consume the team's stored Punchline.

Key Mechanics

• Elation DMG scales with the Elation stat (replacing DMG%) and Punchline — ATK has no effect on Elation DMG. CRIT Rate and CRIT DMG still apply to Elation DMG, making them Yao Guang's primary personal damage stats after SPD.
• Zone uptime is critical — it shares 20% of Yao Guang's Elation to all allies. The Zone lasts 3 of Yao Guang's turns, so higher SPD means more frequent recasting but also faster expiration. Maintaining consistent Skill usage every 3 turns is required.
• The 180 Energy Ultimate cost is the main gating factor. Basic ATK restoring 30 Energy (same as a Skill) is the primary mitigation. Energy Regen from planars (Lushaka, Vonwacq) and Signature LC are important for reaching Ultimate every 3-4 turns.
• Great Boon procs (from Talent during Certified Banger) trigger on every ally attack, doubled when SP is consumed. This makes Yao Guang particularly strong with SP-consuming DPS characters like Archer and Imbibitor Lunae, as each of their attacks triggers 2 instances of Elation DMG.
• Aha's SPD on the action order scales with the SPD of Elation characters in the team. Faster Yao Guang (and other Elation teammates) means more frequent natural Aha Instants, creating a positive feedback loop with SPD investment.

Investment Priority

1. E1 — Best first target for Elation teams. 20% DEF ignore applies to all Elation DMG from the entire team, and the doubled Punchline baseline (40 vs 20) means more Consumed Punchline stored for future Certified Banger states.
2. LC S1 — Signature solves both major weaknesses at once — SPD enables 200 SPD breakpoint for 3 turns in 150 AV and speeds up Aha, while Energy Regen helps reach the 180 Energy Ultimate 1 turn earlier.
3. E2 — Zone grants 12% SPD (key for AV optimization and Aha speed) and 16% Elation teamwide. Strong if pursuing 200 SPD breakpoint — get signature first unless already at SPD threshold.

Important Notes

• 180 Energy cost means roughly 1 Ultimate every 3-4 turns at E0 without Energy Regen investment or Signature LC — plan rotations accordingly.
• Full Elation potential requires at least one other Elation character. General buffs (RES PEN, Vulnerability) carry standalone value, but dedicated supports like Tribbie are often stronger for non-Elation teams.
• Zone lasts 3 turns (counts down at start of Yao Guang's turn) — consistent Skill usage is required to maintain buffs, which can strain SP economy despite A4 recovery.
• A2 SPD-to-Elation conversion starts at 120 SPD (+30% base) and caps at 320 SPD (+230% bonus Elation). Reaching meaningful breakpoints requires heavy SPD investment or Signature LC.
