Word’s out about Saber’s kit in Honkai: Star Rail 3.4, thanks to the Fate/stay night collab. She’s shaping up to be a beastly 5-star Wind character on the Destruction Path. Here’s the full scoop on her skills, playstyle, and team ideas, but keep in mind this is all from leaks and could shift before launch.

Overview

  • Release Date: Saber hits the game on July 11, 2025, in Phase 1 of 3.4 with the "Sweet Dreams and the Holy Grail" event. Her banner’s a one-and-done deal, no reruns expected, so plan your pulls.
  • Rarity and Path: 5-star Wind Destruction character, built to be a main DPS who smashes both single targets and groups.
  • Lore Connection: Her moves pull from her Fate roots, using "Invisible Air" to whip up wind attacks that match her Wind element.

Leaked Kit Details

Saber And Archer Lightcone Eidolon And Model Asset

Saber’s all about stacking Core Resonance to keep her Energy flowing and pump up her damage. Her Ultimate’s got a crazy 360 Energy cost—highest in the game—but she’s got ways to manage it. She thrives on ATK and CRIT stats for big burst hits, especially when teammates pop their Ultimates. Here’s her kit breakdown:

Basic Attack: Invisible Air: Barrier of the Wind King (Single Target)

Smacks one enemy for Wind DMG at 100% of Saber’s ATK (level 6).

  • Enhanced Basic Attack: Release, the Golden Scepter (AoE)Burns Core Resonance stacks to hit all enemies with Wind DMG. If there’s two or fewer foes, it slaps even harder with extra Wind DMG.

Skill: Strike Air: Hammer of the Wind King (AoE)

Deals 150% of ATK as Wind DMG to one main target and 75% to nearby enemies. Gives 2 Core Resonance stacks. Using stacks juices up the damage.

Also boosts her CRIT DMG by 50% for 2 turns (thanks to her A6 Trace, see below).

Ultimate: Excalibur (AoE)

Unleashes a massive Wind DMG blast on all enemies, looking epic in HoYoverse’s previews. Eats up all Core Resonance stacks to make it hit harder. If she’s still got max Energy after firing it off, damage gets another boost.

That 360 Energy cost is rough, but Core Resonance and Eidolons help keep it in check.

Talent: Core Resonance

  • Starts battle with 1 Core Resonance stack.
  • Her Basic Attack or Skill has about a 50-60% shot at adding 1 Core Resonance stack (exact odds still iffy from leaks).
  • Burning 1 Core Resonance stack (with Skill or Ultimate) gives back 10 Energy.
  • Caps at 10 Core Resonance stacks. This is how she keeps her Ultimate ready despite its huge Energy price.

Technique

Pumps up Saber’s ATK by 35% for 2 turns and hands her 2 Core Resonance stacks when the next fight kicks off.

Bonus Traces

  • A2: Knight’s Valor: Gives her a flat 37% CRIT Rate, so you don’t need to stress CRIT stats on relics as much.
  • A4: Oath of the Round Table: When a teammate uses their Ultimate, Saber grabs 3 Core Resonance stacks and gets +40% DMG for 2 turns. Perfect for teams that spam Ultimates.
  • A6: Wind King’s Resolve: After her Skill, she gets 50% CRIT DMG for 2 turns, making her hits sting even more.

Eidolons

Saber’s Eidolons crank up her damage and Energy game:

  • E1: The Lost White Walls: Boosts DMG by 50%. Basic ATK or Skill gives 1 Core Resonance stack.
  • E2: The Sealed Round Table: Adds 50% CRIT DMG to Enhanced Basic ATK and Skill. Each Core Resonance stack tacks on 5% CRIT DMG (up to 10 stacks).
  • E3: The Fabled Fifteen Centuries: Ultimate gets +2 levels, Basic ATK +1 level.
  • E4: The Wondrous Fourteen Nights: Adds 4% Wind RES PEN. Ultimate use stacks 4% Wind RES PEN per stack (up to 4 stacks).
  • E5: The Dreamed Utopian Dawn: Skill +2 levels, Talent +2 levels.
  • E6: The Long Fated Night: Ultimate gets 20% RES PEN. First Ultimate and every 4th one after regenerate 300 Energy.
