About Saber

Saber’s entire kit revolves around her unique Core Resonance mechanic and frequent Ultimate usage. She gains Core Resonance stacks when allies use their Ultimates, when she uses her Skill, and from her Enhanced Basic Attack. Each stack represents 8 Energy that can be converted into actual Energy.

Her Skill deals Blast damage to an enemy and adjacent targets. When Saber has enough Core Resonance stacks to fully regenerate her Energy, using her Skill will consume all stacks, increase the Skill’s damage multiplier by 14% per stack consumed, and fully restore her Energy gauge. This creates incredibly powerful Skill attacks when you accumulate many stacks.

The Ultimate is where Saber truly shines. It deals massive AoE damage to all enemies and grants her the Mana Burst effect. With Mana Burst active, if her next Skill can fully regenerate her Energy through Core Resonance, she immediately takes an extra action and recovers 1 Skill Point for the team.

Best Light Cones for Saber

Choosing the right light cone significantly improves Saber’s damage potential. Here are the best options:

Light Cone Rarity Why It’s Good
A Thankless Coronation 5-Star Her signature with massive CRIT DMG, ATK boosts, and Energy regeneration
Thus Burns the Dawn 5-Star Increases SPD and DMG with DEF Ignore bonus
On the Fall of an Aeon 5-Star Free from Herta Store with ATK increase on hit and Weakness Break
A Trail of Bygone Blood 4-Star Battle Pass option with CRIT Rate, Skill DMG, and Ultimate DMG boosts
Under the Blue Sky 4-Star Increases ATK with additional CRIT Rate after defeating enemies

Best Relics for Saber

Relics are crucial for building Saber correctly. Here’s what you need:

Best Relic Sets

  • The 4 piece Wavestrider Captain is Saber’s best relic set. This set provides significant ATK buffs, which is perfect since Saber will constantly be targeted by support abilities in hypercarry teams.
  • Alternative options include 4 piece Eagle of Twilight Line for Wind DMG bonus, or a mix of 2 piece Eagle of Twilight Line and 2 piece Musketeer of Wild Wheat for balanced Wind DMG and ATK increases.
  • For Skill-focused builds, 4 piece Scholar Lost in Erudition works well. It grants 8% CRIT Rate, 20% Skill and Ultimate DMG, and a 25% boost to your next Skill after using an Ultimate.

Best Planar Ornaments

  • For planar ornaments, use Firmament Frontline: Glamoth for a general damage increase across her entire kit. This set provides DMG bonuses when Speed reaches certain thresholds.
  • Inert Salsotto is another strong choice for CRIT Rate and Ultimate DMG increases when her CRIT Rate reaches 50% or higher.
  • Rutilant Arena works well if you need additional CRIT Rate, providing 8% CRIT Rate and a 20% Basic ATK and Skill DMG increase when CRIT Rate reaches 70% or higher.

Main Stats and Substats

Focus on these stats for maximum effectiveness:

Main Stats:

  • Body: CRIT Rate
  • Feet: Speed
  • Planar Sphere: Wind DMG or ATK%
  • Link Rope: ATK% or Energy Regeneration Rate

Substats Priority:

  • CRIT Rate (aim for 80% total, accounting for her 20% bonus)
  • CRIT DMG (target 120% minimum)
  • ATK%
  • Speed
  • Break Effect%

Stat Targets and Build Tips

Saber has specific stat breakpoints you need to reach:

  • CRIT Rate: Aim for 80% CRIT Rate from your equipment since Saber gets an additional 20% CRIT Rate from her Knight of the Dragon trace. This brings you to 100% CRIT Rate total. If you’re using Sunday in your team, you only need 60% CRIT Rate from equipment since Sunday provides another 20% CRIT Rate buff.
  • CRIT DMG: Target at least 120% CRIT DMG for optimal damage output. Saber already gains substantial CRIT DMG from her Crown of the Star trace (50% when using Skill plus up to 32% from Core Resonance stacks), so balance your CRIT Rate first before focusing heavily on CRIT DMG.
  • Speed: Build Saber with at least 135 Speed to activate the Firmament Frontline: Glamoth effect. If you’re using action advance supports like Bronya, make sure Saber is slightly faster than them to avoid wasting turns.
  • ATK: Since Saber’s damage scales with ATK, prioritize ATK% substats after reaching your CRIT Rate and Speed targets. Her signature light cone provides significant ATK bonuses, making this stat even more valuable.

Best Team Compositions

Saber works best in hypercarry teams where all supports focus on boosting her damage. Here are some of the best combinations:

  • Premium Team: Saber + Sunday + Robin + Huohuo
  • Budget Team: Saber + Bronya + Tingyun + Gallagher
  • Weakness Exploit Team: Saber + Silver Wolf + Sunday + Aventurine
  • Action Advance Team: Saber + Bronya + RMC + Luocha
  • Balanced Team: Saber + Sunday + Asta + Fu Xuan

For bonus abilities, all three are essential. A2 (Knight of the Dragon) gives her 20% CRIT Rate and the Mana Burst mechanic. A4 (Blessing of the Lake) allows excess Energy storage up to 120 and starts battles with 60% Energy. A6 (Crown of the Star) provides massive CRIT DMG boosts when using Skills and gaining Core Resonance.
