Uncrowned Lord of the Ocean

TierA
RolesSupport · Sub DPS
Release1.0

The captain of the Crux is an off-field Electro unit whose Burst chains lightning between enemies every time the active character lands a Normal or Charged Attack, while cutting the damage they take. Her Witch's Revelation upgrade (Luna VIII) made her C6 a real Stellar-Conduct support: Electro and Cryo RES shred plus 200 Elemental Mastery for the active character. Still a strong AoE Burst sub-DPS in classic Electro teams.

Weapons

Favonius Greatsword BiS
4★ · Energy Recharge
Best pick: tons of ER plus particles for the team (build some CRIT Rate).
CRIT hits have a 60% chance to generate particles that restore 6 Energy (once every 12s).
Katsuragikiri Nagamasa
4★ · Energy Recharge
Free craftable: at R5 it nets her 12–15 Energy after her Skill (cast it after her Burst if you can).
+6% Elemental Skill DMG; Skill hits cost 3 Energy but restore 9 Energy over 6s (once every 10s).
Makhaira Aquamarine
4★ · Elemental Mastery
4-star EM claymore that shares ATK with the team; only when her ER needs are low.
Every 10s, grants ATK equal to 24% of Elemental Mastery, and 30% of that bonus to the party.
Skyward Pride
5★ · Energy Recharge
High Base ATK and ER if you have it spare.
+8% DMG; after a Burst, Normal and Charged hits fire vacuum blades dealing 80% ATK (20s or 8 blades).

Artifacts

Noblesse Oblige ×4
Almost always best: she Bursts every rotation.
Set effects
2pElemental Burst DMG +20%.
4pUsing a Burst grants all party members +20% ATK for 12s (does not stack).
Heart of the Furnace ×4
+50% party Stellar Glimmer DMG if nobody better (Odette) holds it; uptime is shaky alongside other Electro units.
Set effects
2pATK +18%.
4pAfter triggering or dealing Stellar Glimmer DMG, the wearer gains +12% ATK and all nearby party members deal +50% Stellar Glimmer DMG for 12s, even off-field (does not stack).

Stat targets

  • Energy Recharge (with Favonius): 160–180% with two other Electro units, 210–230% with one, about 260% as the only Electro
  • Overshooting ER for comfort is fine: her own damage is a small part of these teams
  • HP% boosts her C1 shield; CRIT Rate helps trigger Favonius

Talent priority

Elemental Burst

Normal Attack

Stellar-Conduct replaces Superconduct only when Sandrone, Odette or the Cryo Traveler is in the party. Her C6 buffs then apply while her Burst is active and she stands in a Polestar Field, so cast Q after the first Stellar-Conduct if possible.

Weapons

The Unforged BiS
5★ · ATK%
Top pick: big ATK% stat, and its ATK bonus doubles while her C1 shield (or any shield) is up.
+20% Shield Strength; hits stack up to +20% ATK, doubled to +40% while shielded.
Wolf's Gravestone
5★ · ATK%
Lots of ATK%, best with DMG% buffers like Kazuha.
+20% ATK; hitting an opponent below 30% HP grants the party +40% ATK for 12s (once every 30s).
Serpent Spine
4★ · CRIT Rate
Best 4-star at high refinement once stacked (pre-stack it before combat: her Burst snapshots).
Battle Pass: gains up to +30% DMG while on the field, but each hit taken removes a stack.
Beacon of the Reed Sea
5★ · CRIT Rate
CRIT Rate stat stick with an easy ATK bonus.
+20% ATK after a Skill hit and +20% ATK after taking DMG; +32% Max HP while unshielded.
Akuoumaru
4★ · ATK%
Burst DMG bonus: very strong at high refinements.
+0.12% Elemental Burst DMG per point of the party's combined max Energy (up to +40%).
Favonius Greatsword
4★ · Energy Recharge
Comfort pick when Energy is the bottleneck.
CRIT hits have a 60% chance to generate particles that restore 6 Energy (once every 12s).

Best in slot: converts her high ER into Burst DMG.
Set effects

Recommended teams

Cyno Stellar-Conduct

Cyno
Yae Miko
Odette
Beidou

C6 Beidou is a strong stand-in for C6 Alyosha: triple Electro keeps her ER low and her RES shred boosts everyone. The same core works for Wriothesley, where her shield and damage reduction replace the healer he cannot use.

Sandrone Stellar-Conduct (no Odette)

Sandrone
Yae Miko
Diona
Beidou

Sandrone enables Stellar-Conduct herself; Yae Miko and Beidou bring the Electro, and the two C6 4-stars add Electro/Cryo RES shred, EM, shields and healing.

Taser (budget)

Beidou
Xingqiu
Fischl
Sucrose

Classic all-4-star Electro-Charged team: great AoE for world content and multi-wave fights.

Guide

How to play

How she works

  • Tidecaller (Skill): Tap deals Electro DMG and gives 2 particles. Hold raises a shield and counterattacks on release; getting hit (or, with her new passive, simply holding for 0.8s per stack) builds up to 2 stacks for more damage and an extra particle. A perfect counter (tapping right as you are hit) grants max stacks instantly.
  • Polaris (Witch's Revelation passive): releasing a charged Tidecaller that hits also cuts its cooldown by 4s and restores 8 Energy per stack (once every 15s). Inside a Polestar Field she enters Radiance: Stellar-Conduct.
  • Stormbreaker (Burst, 80 Energy) snapshots her stats and summons the Thunderbeast's Targe for 15s: the active character's Normal and Charged Attack hits release lightning that jumps between enemies (3 hits at C0, 5 at C2, once per second), and they take less damage.
  • C6: enemies near the Targe lose 15% Electro RES; under Radiance: Stellar-Conduct they also lose 15% Cryo RES and the active character gains 200 EM.

Rotation

  1. Hold E (or perfect counter) for particles and Energy, then Q.
  2. Swap to a carry that attacks often with Normal or Charged Attacks.
  3. With a second Electro battery, a quick tap E → Q is enough.

Her lightning shines in multi-target fights; against a single boss it is much weaker.

Strengths

  • At C6, Electro and Cryo RES shred plus 200 EM in Stellar-Conduct teams
  • Strong AoE damage from bouncing lightning, especially at C2
  • Damage reduction and (C1) a shield for the active character
  • Her new passive gives her a big self-battery on Hold Skill

Weaknesses

  • 80-Energy Burst with a 20s cooldown: steep Energy needs
  • Much weaker against a single target
  • Her Stellar-Conduct value is almost entirely locked behind C6
  • Needs a carry that uses Normal or Charged Attacks to trigger the lightning

Notable dupes · Constellation

C1
Solid upgrade

A shield worth 16% of her Max HP on Burst, made much sturdier by the Burst's damage reduction.

C2
Big upgrade

Lightning jumps 2 more times (5 hits): her best damage constellation in multi-target fights.

C6
Big upgrade

15% Electro RES shred, plus 15% Cryo RES shred and 200 EM for the active character under Radiance: Stellar-Conduct (about +18% team damage in Prydwen's Cyno team). Required for her Stellar-Conduct role.
