What it costs to finish this character

1,350

resin, level 1 → 90 and all three talents to 10

2,072,500

mora

days at a minimum, if you spend nothing else

Ascension alone: 760 resin (boss drops only) · talents alone: 590 resin.

Talent domain: Elegance, open Tuesday, Friday, Sunday.

A Crown of Insight is needed for the tenth level of each talent, and crowns are not farmable at any resin price — they come from events.

Materials and mora above are exact, straight from the game’s own tables. The resin figure and the day count divide by an average drop per run, which the game does not publish — they are a community-measured mean, not a promise.

Talents

Tengu Bowmanship

Plunging Attack

Fires off a shower of arrows in mid-air before falling and striking the ground, dealing AoE DMG upon impact.

Tengu Stormcall

Retreats rapidly with the speed of a tengu, summoning the protection of the Crowfeather.

Gains Crowfeather Cover for 18s, and when Kujou Sara fires a fully-charged Aimed Shot, Crowfeather Cover will be consumed, and will leave a Crowfeather at the target location.

Crowfeathers will trigger Tengu Juurai: Ambush after a short time, dealing Electro DMG and granting the active character within its AoE an ATK Bonus based on Kujou Sara's Base ATK.

The ATK Bonuses from different Tengu Juurai will not stack, and their effects and duration will be determined by the last Tengu Juurai to take effect.

The tengu race have never lacked for exceptional talents who have received an Electro Vision. It's just that they often habitually chant praises to the Electro Archon while manipulating Electro. The chants go something like this

"Show forth your might, O praiseworthy Narukami, and grant this supplicant your thunderous might! Sowaka!"

Subjugation: Koukou Sendou

Casts down Tengu Juurai: Titanbreaker, dealing AoE Electro DMG. Afterwards, Tengu Juurai: Titanbreaker spreads out into 4 consecutive bouts of Tengu Juurai: Stormcluster, dealing AoE Electro DMG.

Tengu Juurai: Titanbreaker and Tengu Juurai: Stormcluster can provide the active character within their AoE with the same ATK Bonus as given by the Elemental Skill, Tengu Stormcall.

The ATK Bonus provided by various kinds of Tengu Juurai will not stack, and their effects and duration will be determined by the last Tengu Juurai to take effect.

Sara departed from her people, the tengu, and also temporarily lost her faith in the Tenryou Commission. But once the clouds over her heart cleared, she found her own lightning anew.

Weapons and artifacts

UNSURE This is not a tier list and not community guidance — this product has neither. It is a mechanical shortlist, and the rule is printed so you can check it: Bows of 4★ and above whose secondary stat is one this character’s ascension stat scales with, ordered by base attack at level 90. Weapon passives are not weighed, because a passive is an effect and not a number.

Weapons of the right type and stat
Weapon	Rarity	Base ATK at 90	Secondary stat
Skyward Harp	5★	674	CRIT Rate
The Daybreak Chronicles	5★	674	CRIT DMG
Amos' Bow	5★	608	ATK%
Polar Star	5★	608	CRIT Rate
Thundering Pulse	5★	608	CRIT DMG
The First Great Magic	5★	608	CRIT DMG
Astral Vulture's Crimson Plumage	5★	608	CRIT DMG
Aqua Simulacra	5★	542	CRIT DMG

Sets whose two-piece bonus raises this character’s Electro damage or the stat they ascend into
Set	Two-piece	Four-piece
Resolution of Sojourner	ATK +18%.	Increases Charged Attack CRIT Rate by 30%.
Brave Heart	ATK +18%.	Increases DMG by 30% against opponents with more than 50% HP.
Gladiator's Finale	ATK +18%.	If the wielder of this artifact set uses a Sword, Claymore or Polearm, increases their Normal Attack DMG by 35%.
Thundering Fury	Electro DMG Bonus +15%	Increases the DMG caused by Overloaded, Electro-Charged, Superconduct, and Hyperbloom by 40%, the DMG Bonus conferred by Aggravate by 20%, and the DMG caused by Lunar-Charged and Stellar-Conduct by 20%. When Quicken or the aforementioned Elemental Reactions are triggered, Elemental Skill CD is decreased by 1s. Can only occur once every 0.8s.
Shimenawa's Reminiscence	ATK +18%.	When casting an Elemental Skill, if the character has 15 or more Energy, they lose 15 Energy and Normal/Charged/Plunging Attack DMG is increased by 50% for 10s. This effect will not trigger again during that duration.
Vermillion Hereafter	ATK +18%.	After using an Elemental Burst, this character will gain the Nascent Light effect, increasing their ATK by 8% for 16s. When the character's HP decreases, their ATK will further increase by 10%. This further increase can occur this way a maximum of 4 times. This effect can be triggered once every 0.8s. Nascent Light will be dispelled when the character leaves the field. If an Elemental Burst is used again during the duration of Nascent Light, the original Nascent Light will be dispelled.
Echoes of an Offering	ATK +18%.	When Normal Attacks hit opponents, there is a 36% chance that it will trigger Valley Rite, which will increase Normal Attack DMG by 70% of ATK. This effect will be dispelled 0.05s after a Normal Attack deals DMG. If a Normal Attack fails to trigger Valley Rite, the odds of it triggering the next time will increase by 20%. This trigger can occur once every 0.2s.
Nighttime Whispers in the Echoing Woods	ATK +18%.	After using an Elemental Skill, gain a 20% Geo DMG Bonus for 10s. When under a shield granted by the Crystallize reaction, or when Moondrifts formed by Lunar-Crystallize reactions are nearby, the above effect is increased by 150%. When these conditions are no longer met, this additional increase disappears after 1s.

To turn this into a real recommendation section, add a build dataset — per character, the weapons and sets a community source actually recommends, with the rotation each assumes. Nothing in the game’s published data contains that judgement, and a ranking invented here would be indistinguishable from a researched one, which is why there is not one.

Teams

To build a team section, add team data. Which characters go together is judgement about rotations, energy and shielding that this product does not receive and will not guess at.

What is published is the reaction chart. Electro takes part in:

Overloaded with Pyro
Electro-Charged with Hydro
Superconduct with Cryo
Quicken with Dendro
