Buling

Quick Verdict

Build Buling if you own a Resonance Skill damage dealer — Carlotta and Jinhsi are her tested carries — and you want a free sustain support whose buffs match that profile exactly. She works at S0, but her headline buff only reaches full strength at S6, which for a 4-star is a matter of time, not money. At S6 she roughly matches Verina in Skill-carry teams, while never threatening the dedicated 5-star supports (Shorekeeper, Verina) in general teams.

How Buling Works

Everything in her kit funnels toward one cast: her enhanced Liberation, Flashing Thunder Spell: Harmony.

Step 1 — Trigrams. Her attacks generate Trigram - Mountain (Basic Attack Stage 2) and Trigram - Thunder (Basic Attack Stage 4, her Skill, Mid-air Attack), up to 4 held at once. Holding Normal Attack consumes two highlighted Trigrams into different Heavy Attacks: Mountain + Thunder or double Thunder are the fast routes — and the two that matter are Mountain Over Thunder (damage, granting Minor Yang) and Twin Thunders (a team heal-over-time, granting Minor Yin). One honest warning from the kit: holding Normal Attack with fewer than 2 Trigrams fails the divination — she is briefly immobilized and loses HP, so never force a Heavy on an empty hand.

Step 2 — Yin-Yang Balance and the Array. Holding both Minor Yin and Minor Yang upgrades her Liberation into Flashing Thunder Spell: Harmony: it creates the Five Thunders Spell Array for 24 seconds — an Electro field that keeps inflicting Electro Flare stacks on the targets inside it — and puts the team into Thunder Spell - Primordial Qi. This is where her real buff begins, and it escalates with Intro casts: when any teammate casts an Intro, the state becomes Thunder Spell - Yin and Yang (10% Resonance Skill DMG Bonus to all active Resonators); a second Intro advances it to Thunder Spell - Heaven, Earth, Mind (25% Resonance Skill DMG Bonus — 50% at S6). Note the delivery chain: the buff is tied to her Array window and reaches whoever is on the field, so the team's Intros should be spent inside her 24-second Array, not outside it.

Step 3 — the Outro. Exorcism Spell heals the active Resonator for 16 seconds and grants the whole team 15% DMG Amplification for 30 seconds — general, not type-locked, so every carry uses it fully.

Around this core: her Intro heals and applies 4 Electro Flare stacks (once per 10s), her Skill pulls enemies in, and her Inherent Skills add 25% Healing Bonus when healing targets below half HP. Electro Flare is a Negative Status — the same utility category as Lucilla's Glacio Chafe — so one Buling rotation can switch on game-mode buffs keyed to Negative Statuses for the whole fight, and at high stacks Flare upgrades into Electro Rage, a periodic damage effect on the afflicted enemies.

Tested rotation — identical in both of her tested teams, about 5.65 seconds of field time:

Basic 1, 2, 3, 4 (cancel the 4th with Skill) > Skill > Basic 4 (start holding Heavy immediately) > Heavy Hold (cancel the second Forte with Liberation) > Echo > Liberation > Outro

One string to learn, used everywhere.

Build Priorities

Her page carries no weapon or Echo comparison — her personal damage is about 4% of the team, so nothing about her equipment is about damage. The tested setup tells you what matters:

• Rejuvenating Glow 5-piece — the healer set, which with Fallacy of No Return adds a further team ATK buff on top of her own.
• Energy Regen first. Her entire buff package sits behind an upgraded Liberation every rotation, so Energy Regen is her one real stat requirement — the tested teams run Cosmic Ripples for exactly this reason: before her S2 (which restores 25 Energy per rotation), her Energy demands are noticeably tight.
• Healing Bonus is her only other meaningful stat, with ATK% trailing right behind it for the same reason — her heals scale with her ATK. Crit is decoration on a 4% share.

Talent priority: Normal Attack and Forte Circuit to Lv. 10 (her Trigram/Array engine lives there); Resonance Skill, Resonance Liberation, and Intro Skill to Lv. 6.

Team Fit & Account Value

Her two tested teams define her role precisely: Carlotta with Zhezhi and Buling, and Jinhsi with Zhezhi and Buling.

• Carlotta is her best-tested home. Carlotta's damage is overwhelmingly Resonance Skill-typed, so she uses every piece of Buling's package: the 25% (50% at S6) Skill DMG Bonus, the 15% general Amplification, and the healing — while Zhezhi covers the sub-DPS damage in the same team. The tested version sits in the same band as Carlotta's standard Zhezhi structures, which is exactly where a free support wants to be.
• Jinhsi is the second tested home — see her review for the full picture. The short version: Buling's Skill buffs and healing fit Jinhsi's 68% Skill profile, but she fills the sustain slot, not the gauge slot — she has no Coordinated Attacks, so Zhezhi (or Cantarella) must still feed Jinhsi's Incandescence. One tested caveat repeated in both teams: without a Crit Rate support like Shorekeeper, the carry's average damage dips even when the crit highs look bigger — that is the trade you make when Buling holds the sustain slot instead.
• Untested but mechanically sensible: any other Skill-typed main DPS fits her profile — Phrolova's Resonance Skill share, for example, is large enough that Buling reads as roughly Verina-equal in her teams too. Treat that as mechanics, not tested data, until the projection covers it.

Her honest limits: her headline buff is locked to Skill-typed carries — a Heavy Attack, Liberation, or Basic Attack carry gets only the 15% general Amplification; her healing is tied to her own rotation rhythm; and she competes with Shorekeeper and Verina, whose Crit buffs and shorter rotations keep them ahead in general teams. She is the free specialist for Skill teams, not a budget replacement for the premium generalists.

Sequence Value

Buling works at S0, but her sequences are where a free character becomes a genuinely strong one — and since she is a 4-star, these arrive naturally from playing on any banner. There is no sequence chart on her page; the nodes speak for themselves.

• S1 — Exorcist Gadgets, Lend Me Your Power (2/5): +20% Crit Rate on her Forte Liberation. A personal-damage node on a 4% share — skip the thought.
• S2 — Talisman Burns, Spirits Turn (5/5): Restores 25 Resonance Energy when she enters Yin-Yang Balance (once per 24s). This is the comfort node that stabilizes her Liberation-every-rotation loop and relaxes her Energy Regen requirements — the first one that matters.
• S3 — Summoner of Spirits, Seeker of Fate (2/5): While the Array lasts, teammates dropping below 50% HP get an emergency heal (once per 24s). Nice safety, nothing structural.
• S4 — Wanderer of Solaris, Blessed by Fortune (2/5): +20% Healing Bonus. More of what she already does.
• S5 — Forum Ban? New Account! (4/5): The Array instantly inflicts 6 more Electro Flare stacks on generation — with her Intro's 4, that is the full Electro Rage threshold the moment the field appears. Real Negative Status value.
• S6 — "Almighty Forum Lord of Thunder Spell" (5/5): The node that defines her. Thunder Spell - Heaven, Earth, Mind now grants 50% Resonance Skill DMG Bonus instead of 25% — doubling her headline buff and putting her on par with Verina in Skill-carry teams.

Realistic stopping points: play her at whatever sequence you own; S2 makes her comfortable, and S6 is the destination — reached for free, with time.

Build Value

Since Buling is a 4-star, there is no pull decision — only an investment one.
