Guide

Overview

Ultimate-focused Wind DPS with 360 Energy cost and Core Resonance mechanic. Gains Energy and DMG bonuses from ally Ultimates and delivers massive single-target burst via bouncing Excalibur hits. Requires skilled Ultimate timing to reach her ceiling.

Ultimate-focused Wind Destruction DPS who manages a unique Core Resonance resource to fuel a 360-Energy Ultimate. Ally Ultimates generate Core Resonance (3 per ally Ultimate) and grant 60% DMG buff for 2 turns. Core Resonance converts to fixed Energy (8 per point) via Skill consumption, enabling massive Skill multiplier scaling and triggering Mana Burst action advances. Delivers burst damage through a 280% ATK AoE Ultimate plus 10 bouncing hits at 110% ATK each, followed by an Enhanced Basic ATK.

Key Mechanics

  • Core Resonance is the central resource: generated by ally Ultimates (3 per), own Skill (3 when not consuming), own Enhanced Basic (2), own Talent entry (1), E1 adds +1 per Basic/Skill. Each point converts to 8 fixed Energy when consumed by Skill.
  • Mana Burst (A2) triggers a 100% Action Advance when Skill consumption would fully restore Energy. This advance is uncontrollable — it fires automatically when the threshold is met, which can desync from intended buff windows (e.g., wasting Sunday's Skill advance or misaligning with Robin's Concerto).
  • The 360 Energy cost is the second-highest in the game. Percentage-based Energy restores (Sunday 20%, Huohuo 20%) are exceptionally valuable — each restores 72 Energy. Flat Energy sources (Tingyun 50-60) are proportionally less impactful.
  • Ultimate damage is heavily single-target weighted: 10 bouncing hits concentrate on fewer enemies. Against 1 target, total is 1380% ATK. In AoE scenarios, bounces spread and per-target damage drops significantly.
  • Excess Energy (A4) caps at 120 — Energy beyond Ultimate cost + 120 overflow is wasted. Timing Core Resonance dumps to avoid exceeding this cap is critical for optimal play.

Saber FAQ

Who works best with Saber in HSR?

Saber's best team options include Gilgamesh, Mortenax Blade, Huohuo. StarGuide rates teammates by role and composition fit so the recommendation reflects how the character is actually played.

What relics should Saber use?

Saber's recommended relic setup is Scholar Lost in Erudition with Cosmic Life Sciences Institute, with stat targets around CRIT Rate 100% in-combat, SPD Team-dependent, ATK 2000-2500+ precombat.

What is the best light cone for Saber?

A Thankless Coronation is the top listed light cone for Saber. Signature LC and clear best-in-slot. Provides 54% CRIT DMG at S1 plus 80% ATK for 2 turns on Ultimate use. Critically, if Max Energy is 300 or higher, restores Energy equal to 10% of Max Energy (36 Energy at S1 for Saber's 360 cost), which can push her into the Core Resonance threshold one action sooner, enabling earlier action advances and tighter Ultimate cycles.

How should I invest in Saber?

Saber's first listed investment priority is LC S1. Signature LC provides Energy restore on Ultimate — 36 Energy at S1 (10% of 360) — which can be the difference between reaching the Core Resonance threshold one action earlier. Recommended first investment for most players.

Important Notes

  • High skill ceiling — autoplay and careless Ultimate timing can reduce DPS by 20% or more. Mana Burst advance triggers automatically when Energy threshold is met, which can desync from intended buff windows.
  • SP economy is strained without Sunday signature LC or a dedicated SP-positive sustain. Using Bronya compounds SP pressure significantly.
  • True limited collab character — once the banner ends, she cannot be pulled again. Factor this into pull decisions accordingly.
  • Ultimates used with minimal buffs active or poorly timed relative to Mana Burst advances waste a significant portion of damage potential — deliberate buff window management is essential.

Saber Investment Priority

  1. LC S1 — Signature LC provides Energy restore on Ultimate — 36 Energy at S1 (10% of 360) — which can be the difference between reaching the Core Resonance threshold one action earlier. Recommended first investment for most players.
  2. E2 — Best stopping point after S1. Permanent DEF ignore and the larger Skill multiplier make this Saber's biggest personal jump, though its selfish value has less total-team impact in the Gilgamesh dual-carry shell.
  3. E1 — +60% Ultimate DMG and +1 Core Resonance per Basic ATK or Skill speeds up Energy generation significantly. Strong on the way to E2 but not a recommended standalone stop.

Saber Relics and Stat Targets

Recommended: Scholar Lost in Erudition with Cosmic Life Sciences Institute

Stat targets: CRIT Rate 100% in-combat, SPD Team-dependent, ATK 2000-2500+ precombat

Main stats: Body: CRIT DMG > CRIT Rate · Feet: SPD > ATK% · Sphere: Wind DMG > ATK% · Rope: ATK%

Best Saber Light Cones

  • A Thankless Coronation (Best in Slot): Signature LC and clear best-in-slot. Provides 54% CRIT DMG at S1 plus 80% ATK for 2 turns on Ultimate use. Critically, if Max Energy is 300 or higher, restores Energy equal to 10% of Max Energy (36 Energy at S1 for Saber's 360 cost), which can push her into the Core Resonance threshold one action sooner, enabling earlier action advances and tighter Ultimate cycles.
  • Thus Burns the Dawn: Phainon's signature but effective here. Provides 52.6% CRIT DMG at S1, 24% DEF ignore (separate multiplier stacking with E2 stacks), and 40% DMG buff after Ultimate. Base SPD stat helps reach action-speed thresholds. DEF ignore is multiplicative with other sources. Lacks Energy restore so slightly weaker than signature in practice.
  • I Am As You Behold: Gilgamesh's signature is a usable shared-pair fallback. Saber's 360-cost Ultimate reaches its 72% S1 DMG cap, but the Energy Regen stat does not scale her fixed Core Resonance, joint-attack, or overflow refunds. The 24% team CRIT DMG is also heavily diluted by Gilgamesh's 120% aura, and the cone does not buff Skill, Enhanced Basic, or the joint Follow-up.
  • On the Fall of an Aeon: Best F2P option from Herta Store. Stackable ATK% (up to 64% at S5) and 24% Break DMG bonus at S5. Assumes full ATK stacks maintained and roughly 50% Break DMG uptime. Competitive on pure stats but lacks CRIT DMG and Energy restore, so the gap to signature widens when Energy breakpoints matter.

Teams

Best Saber Teams

Dual Kings

Saber's definitive team. Gilgamesh's shared attack tally launches a joint Follow-up ATK every 8 attacks by the pair, feeding Saber a fixed 120 Energy and doubling her next Ultimate, while his field aura grants her the full 120% ATK and CRIT DMG at her 360 Max Energy. The flex amplifier and Huohuo maximize ally Ultimate frequency, which fuels her Core Resonance and his fixed Energy refunds at the same time. Gilgamesh-less fallback lineups remain playable but lose the comp's core engine.
