Honkai: Star Rail Ellen Build Guide: Best Light Cones, Relics, Materials, and Teams

Hello, Trailblazers!

Ellen is a 5★ Ice character following the Path of Destruction in Honkai: Star Rail. As a collaboration character from Zenless Zone Zero, she is a Shark Thiren maid who specializes in Enhanced Basic ATK damage powered by Shark’s Gotta Bite stacks and her companion summon Sharkboo.

Her kit revolves around generating Shark’s Gotta Bite through ally actions and her Skill, then consuming them for high-multiplier Ice Sea Diving attacks. She has particularly strong synergy with Astra Yao through their unique joint mechanics.

▍ Ellen Character Overview

Ellen is a 5★ Ice character on the Path of Destruction. She functions as a Main DPS / Hypercarry focused on Enhanced Basic ATK damage and follow-up attacks from her summon.

Ellen starts with and generates Shark’s Gotta Bite stacks. When she has 3 or more stacks, her Basic ATK becomes the powerful Enhanced version Ice Sea Diving, which consumes the stacks for massive Blast damage and additional instances.

Her Talent summons Sharkboo, a high-SPD companion that prioritizes Bite Mark targets and provides follow-up damage while helping generate more stacks.

▍ Ellen Skill Breakdown

Ellen’s gameplay centers on stacking Shark’s Gotta Bite and converting them into Enhanced Basic ATKs while maintaining Bite Mark on key targets.

Basic ATK — Saw Teeth Trimming

Deals Ice DMG to one designated enemy. Used when stacks are low or for Skill Point generation.

Enhanced Basic ATK — Ice Sea Diving

Activates when Shark’s Gotta Bite is 3 or higher. Consumes all stacks, applies Bite Mark to the primary target, and deals high Ice DMG to the primary target and adjacent enemies. Extra stacks beyond 3 generate additional random damage instances.

This is her primary damage source and does not recover Skill Points.

Skill — Blizzard du Jour

Gains Shark’s Gotta Bite, applies Bite Mark (increasing Basic ATK DMG taken by the target), and deals Blast Ice DMG. Automatically re-applies Bite Mark to the highest-HP enemy if none remain under the effect.

Ultimate — Welcome to the Ice Age

Deals AoE Ice DMG to all enemies, with bonus damage to targets under Bite Mark. Greatly increases the DMG of her next Ice Sea Diving.

▍ Ellen Trace Priority

Enhanced Basic ATK (Ice Sea Diving) is the core of her damage, so Basic ATK receives the highest priority, followed by Skill and Talent.

Major Traces priority: Roaming Mode > Diving Status > Dining Etiquette.

These improve CRIT DMG from teammate buffs, stack management/Heat conversion, and Sharkboo synergy.

▍ Ellen’s Eidolons

Ellen is fully functional at E0. Early Eidolons significantly improve her resource recovery and damage consistency.

Pull recommendation: E0 is a solid starting point. E1 is the most valuable early upgrade for DEF ignore and resource recovery. E2 further improves Sharkboo uptime and damage. E6 offers strong quality-of-life and damage for dedicated players.

▍ Ellen’s Light Cones

Signature Light Cone — No Shifts on Rainy Days

No Shifts on Rainy Days is Ellen’s best overall Light Cone.

It increases CRIT DMG and Energy Regeneration Rate. Using Basic ATK grants “Snack” (ATK boost), while consuming high Energy on Ultimate grants “Iced Drink” (DEF ignore on Basic ATK and Ultimate). Having both active provides additional DEF ignore. These effects align perfectly with her Enhanced Basic ATK and Ultimate rotation.

Premium Alternative — Thus Burns the Dawn

Strong alternatives that provide SPD, DEF ignore, or stacking ATK. Useful when the signature is unavailable.

Best Free-to-Play Option — On the Fall of an Aeon

On the Fall of an Aeon is Ellen’s best free-to-play Light Cone.

Available from the Herta Store, it stacks ATK on hit and provides a DMG boost after Weakness Break, offering reliable damage that builds quickly with her frequent Enhanced Basic ATKs and Sharkboo follow-ups.

▍ Ellen’s Relics

Best Relic Set — The Edacious Heretic

The Edacious Heretic is Ellen’s recommended Relic set for most hypercarry teams.

• 2-piece effect: Increases Basic ATK DMG.
• 4-piece effect: Further boosts Basic ATK DMG and provides ATK when using Basic ATK.

Since Ice Sea Diving is treated as an Enhanced Basic ATK, this set maximizes her primary damage source.

Alternative Relic Set — Musketeer of Wild Wheat

A solid general-purpose alternative that increases SPD and Basic ATK DMG. Good while farming a full Edacious Heretic set.

Best Planar Ornament — Rutilant Arena

Rutilant Arena is the strongest Planar Ornament for Ellen in most cases.

It increases CRIT Rate and boosts Basic ATK and Skill DMG once the CRIT Rate threshold is met, matching her Enhanced Basic ATK playstyle.

Alternative Planar Ornament — Space Sealing Station / City of Converging Stars

Space Sealing Station provides ATK scaling with SPD, while City of Converging Stars benefits from Sharkboo’s Follow-up ATKs and offers team CRIT DMG.

▍ Ellen Relic Main Stats

Substat Priority: CRIT Rate / CRIT DMG > ATK% > SPD

Recommended endgame targets include:

Focus on balancing CRIT stats while ensuring enough ATK. Energy Regeneration can be valuable if Ultimate uptime is inconsistent.

▍ Ellen Materials Total

Prepare Ellen's materials before investing heavily in her levels and Traces. The following table lists the materials required to raise her from Level 1 to Level 80.

Character Ascension Materials

Trace Materials

Prioritize Basic ATK materials first, as they directly increase Ice Sea Diving damage.

▍ What Are Ellen’s Best Teams?

Ellen performs best as a hypercarry with supports that generate frequent actions (to feed Shark’s Gotta Bite) and provide CRIT/ATK buffs. She has especially high synergy with Astra Yao.

Team 1: Ellen + Astra Yao + Robin • Summeretto + Hyacine

This is currently her strongest team thanks to their unique joint mechanics.

Astra Yao enables powerful automatic Enhanced Basic ATKs and extra turns after Ultimates through their special interaction. Robin • Summeretto provides strong teamwide offensive buffs and damage amplification, while Hyacine keeps the team stable during extended damage windows.

Team 2: Ellen + Astra Yao + Tribbie + Huohuo

A flexible and highly effective hypercarry setup that still leverages the Astra Yao synergy.

Astra Yao remains the core joint partner, while Tribbie delivers reliable buffs and utility. Huohuo provides healing and Energy regeneration, ensuring consistent rotations and high uptime on Shark’s Gotta Bite.

2. Should I pull her signature Light Cone or Eidolons first?
