Saber, the beloved king from Fate, has finally entered Honkai: Star Rail as a Wind Destruction character—and yes, she brings Excalibur with her. This guide will walk you through her kit, builds, best relics, light cones, eidolons, and team setups. Whether you’re a Fate fan or just looking for a strong new DPS, here’s everything you need to know to make Saber shine. Check out our Honkai Star Rails Archer Guide.

Saber’s Role & Strengths

Saber is a Wind Destruction unit with high base ATK and Defense, making her a tough, self-sufficient damage dealer. What makes her special is her Core Resonance mechanic, a system that turns her energy generation into a strategic mini-game. She has very high energy cost, but her kit is designed to fuel itself—when played right, she can loop her ultimates with ease.

Understanding Saber’s Core Kit

Core Resonance System

Saber builds up Core Resonance via her skill, basic attacks, and passives. Each stack holds 8 energy as potential, which doesn’t immediately fill her ult gauge but stays “stored.” When her actual energy plus stored energy reaches her max (360), she gets bonus effects:

• Skill gains increased multiplier based on number of stacks.
• She consumes all stacks and gains energy equal to the value (e.g. 10 stacks = 80 energy).

This is called her “consume skill”, which is key to her combo flow.

Skill

Her skill does AoE damage. If she meets the Core Resonance energy threshold, it:

• Hits harder (bonus multiplier per stack)
• Consumes stacks and refills energy
• Often leads directly into her Ultimate

Ultimate – Excalibur

Deals AoE damage, followed by 10 bounce hits focused on surviving enemies. After using it, she gets an enhanced basic attack that:

• Deals AoE
• Gains extra multipliers based on enemy count
• Builds Core Resonance

Talent

Every time she or allies use an Ultimate, she:

• Gains a damage buff
• Gains more Core Resonance

Combined with frequent ults and strong support, this makes Saber scale as fights go on.

Passives

• A2: Grants 20% CRIT Rate in combat and allows Saber to advance forward when she reaches max energy.
• A4: Grants overflow energy (up to 120) and 60% starting energy at battle start.
• A6: Flat 82% CRIT DMG bonus through Core Resonance stacking—huge damage potential.

Eidolon Breakdown

• E1: More damage on ult and extra Core Resonance from basics and skills.
• E2: Ignores DEF and gains more damage from each Core consumed.
• E4: Adds RES PEN stacking from using her ult (up to 20% total).
• E6: Generates 300 energy after her first ult and then again every 3 ults—massively increases ultimate uptime and lets her loop ults nearly back-to-back.

Best Relics for Saber

Main Sets

• Wavestrider: 48% ATK after ulting, buffs skill and enhanced basic.
• Scholar Lost in Erudition: Consistent skill/ult damage boosts.

Planar Ornaments

• Glamoth
• Rutilant Arena
• Inert Salsotto
• Space Sealing Station

Choose based on substats and personal gear quality. All of these are solid for Saber.

Stat Priority

• Body: CRIT DMG
• Boots: SPD or ATK (SPD preferred for better rotations)
• Orb: Wind DMG or ATK

Target Stats:

• 2.5k–3k ATK
• 135 SPD
• 100% CRIT Rate (20% comes from A2)
• Reasonable CRIT DMG (she self-buffs a lot)

Best Light Cones for Saber

A Thankless Coronation:

• 36% CRIT DMG
• ATK% buffs when ulting (up to 80%)
• Regenerates 10% max energy
• Best-in-slot and fits her kit perfectly

F2P Options:

• On the Fall of Aeon (F2P-friendly, strong for her rotation)
• Other Destruction cones that boost ATK or Ult DMG can work too.

Saber Team Synergies

Saber is flexible, but energy and turn control units make her smoother to play.

Top Support Picks:

• Sunday – Adds 72 energy and keeps buffs up through Saber’s many turns. Essential for energy-focused comps.
• Bronya – No energy buff, but still solid due to high damage amplification and support versatility.
• Robin – High ATK buffs and team-wide advance. Amazing for Saber’s combo loop.
• Tingyun – Good alternative if Robin isn’t available; provides Energy and ATK buffs.
• Ruan Mei / Cipher / SW / RMC – General buffers or support units that can enable rotations.

Sustain Options:

• Huohuo – Energy batteries and healing. Perfect match.
• Gallagher – Versatile F2P sustain, flexible builds.
• Hyacine – Wind sub-DPS healer. Works well on Wind stages.

Recommended Teams

1. Premium (AoE): Saber / Sunday / Robin / Huohuo
2. Element-Focused: Saber / Sunday / Tribbie / Hyacine
3. F2P-Friendly: Saber / Tingyun / Bronya or Sunday / Gallagher

Saber is a satisfying, energy-focused DPS with a stylish gameplay loop. Her reliance on energy might feel a little awkward at times, especially with turn manipulation, but with the right team, she can chain ultimates and output consistent high damage.

She’s not top-tier broken, but she’s a strong addition to any team and a must-pull for Fate fans. With support scaling and energy-centric mechanics in HSR evolving, her future looks promising.

If you’re building her, aim for SPD, ATK, and CRIT-focused gear—and be ready for some flashy Excalibur action. Let Saber lead your climb to the top of Memory of Chaos. She’s not just a king—she’s a full-on burst engine waiting to be unleashed.
