Guide
How the kit works
Start by collecting Trigrams with Hexagram Calls, Lightning Falls. Basic Attack Stage 2 grants Mountain, while Stage 4 grants Thunder. With Mountain followed by Thunder, hold Normal Attack to use Heavy Attack - Mountain Over Thunder and gain Minor Yang.
Next, cast In Shadow Thunder Stirs for a Thunder Trigram and to pull nearby targets. Press Normal Attack right afterward for Basic Attack Stage 4 and another Thunder. Hold Normal Attack with those two Thunder Trigrams to use Heavy Attack - Twin Thunders, heal nearby teammates once per second for 8 seconds and gain Minor Yin.
With both Minor Yin and Minor Yang, Thunder Begets Life replaces Flashing Thunder Spell with Flashing Thunder Spell: Harmony. Cast it to create a 24-second array that deals Electro DMG and applies 2 stacks of Electro Flare every 2 seconds. One Intro Skill during the array grants the active Resonator 10% Resonance Skill DMG Bonus; a second raises it to 25%.
Summon and Smite heals nearby teammates, and its hits apply 4 Electro Flare stacks once every 10 seconds. Exorcism Spell heals the active Resonator by 18% of Buling's ATK per second for 16 seconds and amplifies nearby teammates' damage by 15% for 30 seconds.
Build and why
Use the recommended five-piece Rejuvenating Glow. Its listed two-piece effect gives 10% Healing Bonus, which suits Buling's healing. The supplied data does not describe its five-piece effect. Two pieces of Moonlit Clouds are another option for 10% Energy Regen.
Stellar Symphony is the first weapon to consider from the guide recommendations. It restores 8 Concerto Energy when casting Resonance Liberation, once every 20 seconds. Its team ATK effect requires a Resonance Skill that heals; Buling's listed Skill does not heal, so don't count on that effect.
Variation restores 8 Concerto Energy when Buling casts her Skill, once every 20 seconds. Cosmic Ripples gives 12.8% Energy Regen and increases Basic Attack DMG when Basic Attacks deal damage. For stats, ATK suits her Outro healing, while Energy Regen and Healing Bonus are worth considering for her support kit.
Leveling priority
A suggested order is Hexagram Calls, Lightning Falls, Summon and Smite, Thunder Begets Life, In Shadow Thunder Stirs, then Flashing Thunder Spell. This puts the attacks used for healing and the enhanced Liberation ahead of the regular Liberation. Exact stat increases from skill levels are not provided.
For maximum ascension, collect 170,000 Shell Credit, 4 LF Whisperin Core, 12 MF Whisperin Core, 12 HF Whisperin Core, 4 FF Whisperin Core, 46 Blighted Crown of Puppet King and 60 Pecok Flower.
For all skills, collect 2,030,000 Shell Credit, 25 LF Whisperin Core, 28 MF Whisperin Core, 40 HF Whisperin Core, 57 FF Whisperin Core, 26 Curse of the Abyss, 25 Lento Helix, 28 Adagio Helix, 55 Andante Helix and 67 Presto Helix.
Resonance Chain nodes worth it
For team damage, consider "Almighty Forum Lord of Thunder Spell" (sequence 6) first. It raises the final Resonance Skill DMG Bonus from 25% to 50%. Talisman Burns, Spirits Turn (sequence 2) is another useful option: entering Yin-Yang Balance restores 25 Resonance Energy, once every 24 seconds.
Forum Ban? New Account! (sequence 5) adds 6 Electro Flare stacks when the array appears. Summoner of Spirits, Seeker of Fate (sequence 3) offers an emergency heal when a teammate's HP drops below 50% while the array is active, once every 24 seconds.
You can leave Sequence 1 and Sequence 4 for later if you prefer the team damage and energy upgrades. They improve Harmony's Crit. Rate and Buling's Healing Bonus respectively.
Teams
Pair Buling with a damage dealer who benefits from Resonance Skill DMG Bonus. Her array needs two Intro Skills to reach its larger bonus, so plan the switches around the character you want to keep active. Her Outro damage amplification also supports nearby teammates.
Common mistakes
Don't hold Normal Attack with fewer than two Trigrams. Heavy Attack - Ghost Gate Omen removes the Trigrams, temporarily immobilizes Buling and costs 20% of her current HP. Watch their order too: two matching Trigrams heal, while a mixed pair grants Minor Yang.
Don't cast the regular Liberation expecting the array. Get both Minor Yin and Minor Yang first. Once the array is active, remember the two Intro Skills needed for the full Resonance Skill bonus.
Buling can hold four Trigrams. At the limit, gaining another shifts them left and removes the leftmost one, which can change the pair you planned to use. Check the highlighted pair before holding Normal Attack.
