Release6.1

Jade Knight is Li Sushang's S-rank PSY-type Ice sword user: she rides a Sword Array of flying blades, then calls down a sky-splitting sword with her Ultimate to give every Ice DMG dealer Elemental Breach. She is still the best support for Part 1 Ice teams thanks to her Breach, team Ice buffs and shield breaking, but those teams are no longer used in current endgame (Marisa Impact). She has no Astral Ring and only becomes decent from SS rank.

Part 1 Ice support

Weapons

Nocturnal Stealth: Beam BiS

Best in slot (BBS): team +20% Ice DMG and +10% Total DMG, and 12 SP per Torrent wave on her.

Jade Knight's PRI-ARM gauntlets: the weapon skill leaves a Torrent that sends waves on every Ice hit, gives the team +20% Ice DMG and +10% Total DMG, and on Jade Knight each wave restores 12 SP.

Nocturnal Stealth

Marisa Impact calls it a must-have to keep up with her Ultimate's SP cost; now in the Exchange House.

Jade Knight's signature gauntlets: the same Torrent with weaker waves, the same +20% team Ice DMG after the weapon skill and, on Jade Knight, the 12 SP refill per wave that powers her Ultimate (values at max level). No team Total DMG buff.

Cosmic Duality

Farmable option (Marisa Impact, BBS): its weapon active restores SP over time, but you lose the Back Wind Slash chain.

PRI-ARM of Nebulous Duality for Fu Hua: its active gives Ignore Interrupt and restores HP and SP for 10s, a teammate's Ultimate restores 10 SP and 300 HP to the wielder (CD: 15s), and on Fu Hua each charge gives teammates +5% Total DMG when she switches out (up to 15%).

Stigmata

Eternal Moon T Top

Eternal Moon M Middle

Eternal Moon B Bottom

Best in slot (Li Sushang: Shenzhou Reminiscence): big team Ice buffs and +50% shield-breaking efficiency on the 3-piece bonus. The G4 set is craftable in the Foundry.

Set effects

2pIn Reinforcement (after spending 120+ SP), team Ice DMG stacks Menacing Sword Ki on enemies (+1% Ice DMG taken per stack; up to 22 on Jade Knight), and her QTE can trigger Reinforcement with the B piece.

3pMax Sword Ki stacks +15, marked enemies take 30% ATK of Ice DMG per second, and the team breaks shields 50% more efficiently.

Turgenev T Top

Beach Party M Middle

Turgenev B Bottom

Farmable option (Marisa Impact, BBS): G3 Turgenev T/B from the Foundry with Mei: Beach Party M from the Exchange House.

Set effects

2pRebel's Gun set. Every 6 hits from the wearer or her summons extend Hunter Mark (applied by the B piece) by 2s, up to 12s; marked enemies take 21% more Elemental DMG.

3pThe wearer's Ultimate and summons deal 25% more Total DMG; while her summons are on the field, the team deals 25% more Ice DMG to marked enemies.

2pAttacks have a 12% chance to summon HOMU King, who knocks enemies down for 450% ATK of Physical DMG (CD: 16s).

3pWhen HOMU King appears, every ally gets a Flame Wreath that burns nearby enemies for 6s.

Stat targets

Stigmata affixes: ATK on every piece (Marisa Impact)
Aim for SS rank before investing: it doubles her Ultimate's Ice DMG and unlocks her extra SP
Keep her Elemental Breach up at all times; don't pair her with another Breach-state support

Talent priority

Ultimate

Special ATK

Passive

Leader

Basic ATK

Evasion

Where to get her: starter event, War Treasury and battle pass; she and her signature gear were sold in the v8.3 battle pass Reserve Works, and Nocturnal Stealth and Eternal Moon were added to the Exchange House in v8.8 (Marisa Impact, official notes).

Guide

How to play

Cutting Form and Sword Array

Her Basic ATK is a 4-form combo played with both [ATK] and [ULT]: Opening, Transform, Guard and Wrath. Each hit builds Blade Sanction (max 200), and the Wrath forms give Iron Body and 50% damage reduction.
At full Blade Sanction, hold ATK for her Combo ATK Refining Ascension: Wild Swords pulls enemies together and opens Sword Array mode. She then stands on a flying sword with Iron Body: tap ATK for Cloud Cutter, tap ULT for Bolt Slash, tap EVA to blink between swords.
After 3 Bolt Slashes, tap ATK for Back Wind Slash (+20 SP, +50% ranged Ice DMG for the team). Finish with Heart Piercer (hold ATK): 14 hits and 3s of global Time Fracture, and she stays on the field while you switch out.
With Nocturnal Stealth, casting the weapon skill in Sword Array chains straight into Back Wind Slash, and each Torrent wave restores 12 SP: this is what keeps her expensive Ultimate running.

Crowning Eminence

150 SP (up to 25 extra SP is consumed for more damage and team Ice DMG): a sky-reaching sword that deals 1800% ATK under Time-frozen Domain. It gives every Ice DMG dealer 17% Elemental Breach on ranged, Basic, Charged, Combo and burst attacks for 18s. Recast it just before the Breach expires.
Her QTE triggers on a teammate's Combo/Charged ATK or Ultimate and opens Sword Array instantly with full Blade Sanction.

Marisa Impact's loop: get SP, Ultimate, hold ATK to enter Sword Array, weapon skill into Back Wind Slash, spam ATK, and recast the Ultimate when the Breach icon above the HP bar is about to run out.

Strengths

Still the best Part 1 Ice support: Elemental Breach, big team Ice buffs and shield breaking (Marisa Impact).
Her signature stigmata give buffs equal to handing G4 Willows to the whole team, plus +50% shield-breaking efficiency.
Lots of invincibility and Iron Body, global Time Fracture on Heart Piercer and QTE entry.
Free from the starter event, and her gear is now in the Exchange House and the Foundry.

Weaknesses

Part 1 Ice teams are not used anymore, and she has no Astral Ring.
Very weak at S0: this kind of farmable S-rank only becomes decent from SS rank (Marisa Impact).
Her 150+ SP Ultimate is hard to sustain without Nocturnal Stealth.
Her Elemental Breach state does not stack with other Breach states (Azure Empyrea, Senadina, Thelema).

Notable dupes · Rank

Solid upgrade

Bolt Slash costs 10 less Blade Sanction and auto-casts Cloud Cutter: a smoother Sword Array.

Big upgrade

The key rank: her Ultimate deals +100% Ice DMG and breaks shields 200% easier (team +25%), Back Wind Slash fires 3 giant swords and restores 5 extra SP, and her team Breach goes from 14% to 17%.

SS1

Solid upgrade

Wild Swords and Heart Piercer give the team +10% Ice DMG (20% at SSS).
