Mastering Helia "Plane Weapon: Disordered Spacetime" in Honkai Impact 3rd v8.3: Ultimate Build Guide

Helia "Plane Weapon: Disordered Spacetime" is a 5★ BIO-type Lightning DPS introduced in Version 8.3, specializing in rapid Ultimate spams and team energy synergy via the Star Ring: Cup of Heavenly Calculation. This guide covers optimal builds, rotations, and advanced tactics to maximize her performance in endgame content like Superstring Dimension and Memorial Arena.  

1. Core Mechanics & Playstyle  

Key Abilities  

- Normal Attack: 3-hit Lightning DMG combo. Air attacks generate energy.  

- Ultimate (Burst): 3-stage sequence consuming energy:  

  - Each stage grants 1 stack of Scorch Light and applies Paralysis.  

  - Post-Ultimate, gains Floating Pivot buff, enabling follow-up attacks ("Wandering Edge") for extra energy regen.  

- Star Ring: Cup of Heavenly Calculation:  

  - Team Energy Sharing: During Star Ring Burst, team energy cap = sum of all members' max energy.  

  - "Derivation" Mechanic: Using skills generates Spark Traces. At 2 stacks, Branch/Combo Attacks deal bonus Lightning DMG.  

Role Breakdown  

- Burst DPS: Excels in rapid Ultimate cycling (3-stage sequence) for sustained AoE Lightning DMG.  

- Energy Battery: Star Ring enables team-wide energy regeneration, supporting energy-hungry allies.  

2. Optimal Gear & Stats  

Weapons  

| Weapon               | Role          | Effect                                                                 |  

|--|-|-|  

| Scourged Ashen Return (BiS) | Hypercarry       | +40% Lightning DMG; Ult hits grant +15% ATK (stacks 3x). |  

| Key of Radiance      | F2P Alternative   | +30% CRIT DMG; Burst boosts team Lightning RES shred.                      |  

| Echo of Paradise     | Energy Support    | +25% Energy Regen; Ult restores 15 team energy.                            |  

Stigmata  

- Destiny's Choice (4pc BiS):  

  - 2pc: +20% Lightning DMG.  

  - 3pc: Ult stages reduce enemy Lightning RES by 15% per stack (max 45%).  

- Alternatives:  

  - Handel (2pc) + Darwin (2pc): +15% Lightning DMG + 30% Total DMG.  

- Main Stats:  

  - ATK/CRIT DMG (Timepiece) → Lightning DMG (Goblet) → CRIT Rate (Circlet).  

- Substats Priority: CRIT Rate/DMG > ATK% > Energy Regen (120% recommended).  

3. Team Compositions  

Lightning Burst Core  

| Character          | Role                  | Synergy                                                                 |  

|-||--|  

| Helia (Disordered Spacetime) | Main DPS          | Triggers multi-stage Ult; provides team energy.                             |  

| Fischl (Prinzessin) | Off-field DMG/Support | Summons Oz for consistent Lightning procs; reduces enemy Lightning RES.     |  

| Eden (Golden Diva)  | Battery/Buffer    | Generates SP; boosts team Lightning DMG by 40% during Ult.      |  

Star Ring Synergy Teams  

- Helia + "Yike Xiaoyou" (Li Sushang):  

  - Li Sushang’s Star Ring: Synergy Resonance allows QTE entries to use Ult without energy cost.  

  - During Star Ring Burst, her attacks rapidly refill team energy and accelerate Derivation stacks.  

4. Rotation & Playstyle  

Optimal Sequence  

1. Setup:  

   - Activate supports (e.g., Fischl’s Oz → Eden’s Ult).  

2. Energy Buildup:  

   - Helia: Normal Attack → Trigger Floating Pivot → Use Wandering Edge for energy.  

3. Burst Phase:  

   - Activate Star Ring Burst → Spam 3-stage Ultimate.  

   - At 2 Derivation stacks, use Branch Attack → Combo Ult "Clear Sky" for nuke DMG.  

4. Reset: Swap to supports to recharge energy.  

Energy Management Tips  

- Prioritize Scourged Ashen Return for Ult spamming.  

- Under Star Ring Burst, use high-energy allies (e.g., Eden) to maximize team energy pool.  

5. Advanced Techniques  

1. Paralysis Lock:  

   - Chain Helia’s Ult with Fischl’s Oz to paralyze elites/bosses, enabling safe DPS windows.  

2. Derivation Stacking:  

   - Pre-cast supports’ skills before Helia’s Burst to instantly gain Spark Traces.  

3. Animation Cancel:  

   - Dash after the 3rd Ult stage to skip recovery frames.  

6. Endgame Content Adaptation  

- Superstring Dimension:  

  - Against "Bloodthorn - High Risk" (Herrscher of Sentience), save Combo Ult for her "Dreamlike Flower" phase.  

- Memorial Arena:  

  - Vs. SSS "Masked Fool" Sampo: Use Star Ring Burst during his evasion phase to burst through shields.  

7. Acquisition & Investment Priority  

- Gacha: Pull from "Path Revealed" banner (90-pity guarantee; first 10-pull 50% off).  

- Stigmata Crafting: Forge Destiny's Choice with ×2 Primordial Prisms + ×600 Aether Fuel.  

- Priority Constellations:  

  - C1: +20% Lightning DMG during Star Ring Burst.  

  - C6: Combo Ult "Clear Sky" triggers twice, doubling nuke DMG.
