Tingyun Build Guide: The Ultimate Buff Bot

Tingyun, the elegant and powerful follower of the Storm-Blessed, is a premier 4-star Harmony character in Honkai: Star Rail. Her ability to provide ATK buffs, DMG buffs, and Energy regeneration makes her an indispensable support for almost any DPS unit. This guide will cover the optimal Light Cones, Relics, Planar Ornaments, and Traces to maximize her support capabilities.

Tingyun's core strength lies in her Skill, Soothing Melody, which grants a DMG buff and the 'Wanderup' buff to a single ally. Her Ultimate, Dance of Graceful Steps, restores Energy to the buffed ally and further increases their DMG. Her Talent, The Opulent Gesture, allows her basic attacks to deal additional Lightning DMG when an ally with 'Wanderup' attacks.

Recommended Light Cones:

Carve the Moon, Weave the Clouds (4-Star): Tingyun's best 4-star option, offering a random buff (ATK, CRIT DMG, or Energy Regeneration) to all allies at the start of combat and when her Ultimate is used.
Dance! Dance! Dance! (4-Star): Useful for advancing all allies' actions when Tingyun uses her Ultimate, boosting turn economy.
Past and Future (4-Star): Increases the DMG of the next ally to act after Tingyun uses her Skill, directly buffing your main DPS.
Chorus (3-Star): A budget-friendly option that increases the ATK of all allies.

Recommended Relics:

Focus on Relics that enhance her buffing and utility:

4-Piece Musketeer of Wild Wheat: Provides ATK and SPD buffs, which are beneficial for her to act more often and amplify her buffs.
2-Piece Musketeer of Wild Wheat + 2-Piece Messenger Traversing Hackerspace: A good balance for ATK and SPD.
2-Piece Fleet-Footed Messenger + 2-Piece Passerby of Blazing Laire: If you need more survivability and Speed.

Planar Ornaments:

2-Piece Broken Keel: Grants Effect RES and, importantly, a CRIT DMG buff to all allies when her Effect RES is met. This is her best-in-slot ornament set.
2-Piece Sprightly Vonwacq: Increases her Energy Regeneration Rate, allowing for more frequent Ultimate usage, which is crucial for her kit.

Stat Priorities:

Prioritize these stats for Tingyun:

SPD: Essential for her to act frequently and reapply buffs. Aim for as high as possible, ideally above 134.
Energy Regeneration Rate: Crucial for her Ultimate.
ATK%: Directly increases the ATK buff she provides.
Effect RES: Important for activating Broken Keel.
HP/DEF: For survivability.

Traces:

Upgrade these Traces in order of importance:

Dance of Graceful Steps (Ultimate): Her most impactful ability for massive DMG buffs and Energy restoration.
Soothing Melody (Skill): The primary buffing tool for your main DPS.
The Opulent Gesture (Talent): Enhances her damage output when her buffed ally attacks.
General Stat Boosts: Focus on SPD, ATK, and Energy Regeneration Rate.

With this build, Tingyun will consistently provide massive buffs to your team, significantly boosting their damage output and enabling them to overcome even the most challenging content in Honkai: Star Rail.
