Blade Build Guide: Best Relics, Light Cones & Stats

Updated 8 November 2026 · Standard formula, shown below

This guide explains how to build Blade in Honkai: Star Rail, covering his best light cones, relic sets, planar ornaments, stat priorities, and team compositions. You’ll get a complete, accurate build framework based on his kit’s mechanics so you can maximize his damage output.

Blade’s Kit and Why It Shapes His Build

Blade is a Wind-element Destruction character whose damage scales primarily with his Max HP, not his Attack. His basic attacks, skill, and ultimate all deal damage based on a percentage of his Max HP, and his talent causes him to gain stacks of Charge whenever he takes damage or loses HP. At 5 stacks, Blade unleashes a follow-up attack against all enemies, which is a major source of his total damage. This unique mechanic means that building HP is more valuable than building ATK, and that he wants to take damage frequently to trigger his follow-up.

His ultimate is also special: it costs no energy and instead consumes 50% of his current HP to deal damage to a single enemy and adjacent targets. The damage of this ultimate is based on his Max HP, his ATK, and the HP he has lost during the battle, making HP and damage taken both important for his burst. Because of these mechanics, the best build focuses on HP%, Crit stats, and Speed, while largely ignoring ATK.

Best Light Cones for Blade

The light cone you choose significantly affects Blade’s performance. His signature light cone, The Unreachable Side, is his best-in-slot because it increases his Crit Rate, Max HP, and grants a massive Damage Boost that increases when he takes damage or consumes HP. However, several other options work well, especially if you’re free-to-play or don’t have his signature.

5-Star: The Unreachable Side (Best) – Increases Crit Rate by 18%, Max HP by 18%, and grants a 24% Damage Boost that increases by an additional 24% when the wearer takes damage or consumes HP. This perfectly synergizes with Blade’s kit.
5-Star: Something Irreplaceable – Increases ATK by 24% and restores HP when the wearer defeats an enemy or is hit. While the ATK buff is not ideal, the HP restoration helps sustain Blade’s HP loss, and the damage boost is conditional.
4-Star: A Secret Vow – Increases DMG by 20% and increases DMG against enemies with higher HP percentage. This is a strong free-to-play option that boosts Blade’s damage directly.
4-Star: The Moles Welcome You – Increases ATK and grants stacking ATK boosts on hits. The ATK is not ideal, but it’s a decent fallback if you have nothing else.
4-Star: Nowhere to Run – Increases ATK and restores HP on defeating an enemy. The HP restoration is useful for sustain, but the ATK scaling is wasted.

Best Relic Sets

Relic sets are crucial for boosting Blade’s stats. The best sets focus on HP%, Wind Damage, and Crit stats. Mixing and matching two-piece sets is often more effective than using a four-piece set that doesn’t fully synergize.

Longevous Disciple (4-piece) – Increases Max HP by 12% and increases Crit Rate by 8% for 2 turns after taking damage. This is Blade’s best relic set because it provides HP and Crit Rate, both of which he needs, and he takes damage constantly.
Longevous Disciple (2-piece) + Messenger Traversing Hackerspace (2-piece) – This combination gives 12% HP and 6% Speed. Speed is valuable for Blade to act more often, which means more damage and more chances to take damage.
Longevous Disciple (2-piece) + Eagle of Twilight Line (2-piece) – Provides 12% HP and 10% Wind Damage Boost. This is a good alternative if you have a separate Wind Damage orb.
Longevous Disciple (2-piece) + Wastelander of Banditry Desert (2-piece) – If you’re using a team that applies debuffs, the 10% imaginary damage boost is wasted, so avoid this unless you have no other option.

Best Planar Ornaments

Planar ornaments provide additional set bonuses. For Blade, the best options are:

Rutilant Arena (Best) – Increases Crit Rate by 8% and increases Basic Attack and Skill DMG by 20% when Crit Rate is 70% or higher. Blade’s basic attack and skill are his main damage sources, so this is ideal.
Inert Salsotto – Increases Crit Rate by 8% and increases Ultimate and Follow-up Attack DMG by 15% when Crit Rate is 50% or higher. This is a strong alternative if you focus on his ultimate and follow-up attacks.
Space Sealing Station – Increases ATK by 12% and increases ATK by 12% more when Speed is 120 or higher. The ATK boost is less valuable for Blade, but the Speed bonus can be useful.

Stat Priority and Sub-stat Goals

Blade’s stat priorities are straightforward: HP% and Crit stats are king, with Speed being a valuable secondary stat. ATK% is almost useless for him, so avoid it in sub-stats.

Body: Crit Rate or Crit Damage (aim for a 1:2 ratio)
Feet: Speed (to act more often) or HP% (if you need more survivability)
Planar Sphere: Wind DMG Bonus (or HP% if you don’t have a good Wind orb)
Link Rope: HP% (Energy Regen is not needed since his ultimate doesn’t cost energy)

For sub-stats, prioritize in this order: Crit Rate/Damage > HP% > Speed > Flat HP > ATK%. Aim for at least 70% Crit Rate to activate Rutilant Arena’s bonus, and as much Crit Damage as possible. A good benchmark is around 70% Crit Rate and 140% Crit Damage, with 6,000+ HP.

Team Compositions and Synergies

Blade works well in teams that can either heal him (since he loses HP constantly) or buff his damage. He doesn’t rely on energy, so he fits into teams without a dedicated energy support.

Hypercarry Team: Blade + Bronya (or Tingyun) + Healer (Luocha, Bailu, or Natasha) + Flex (Pela or Silver Wolf). Bronya’s skill lets Blade act more often, and her damage buff is excellent. Luocha is his best healer because he can heal without consuming skill points, and his field heals allies when they attack.
Dual DPS Team: Blade + Jingliu or Clara + Healer + Support. Blade can work as a sub-DPS, especially with Jingliu, as her HP drain triggers his follow-up attacks.
Free-to-Play Team: Blade + Asta (for Speed) + Natasha (healer) + Pela (defense shred). This team provides decent support without requiring 5-star characters.

When pairing Blade with a healer, remember that his ultimate consumes 50% of his current HP, so he needs consistent healing to stay alive. Healers like Luocha or Bailu are ideal because they can heal reactively.

Common Mistakes and Misconceptions

One of the most common mistakes is building ATK% on Blade. Since his damage scales with HP, ATK% is nearly useless. Another mistake is ignoring Speed. While Blade’s damage is high, acting more often means more damage and more opportunities to take damage and trigger his follow-up. Don’t forget that his ultimate doesn’t cost energy, so Energy Regen is wasted on him.

Another misconception is that Blade needs to be at low HP to deal damage. While his ultimate’s damage increases based on HP lost, his basic attacks and skill always scale with Max HP. Keeping him at high HP is fine; you just want to make sure he’s taking damage to build his Charge stacks.

Frequently Asked Questions

Is Blade worth pulling?

Yes, Blade is a strong and versatile DPS character. He deals consistent damage, has a powerful follow-up attack, and is relatively easy to build because he only needs HP and Crit stats. He also works well in many team compositions, making him a valuable addition to any account.

What is the best 4-star light cone for Blade?

A Secret Vow is generally considered his best 4-star light cone because it provides a direct damage boost. The Moles Welcome You is also decent, but the ATK scaling is less useful. If you have no other options, Nowhere to Run can work for the HP restoration, but it’s not ideal.

Should I use HP% or Wind DMG% on his planar sphere?

Wind DMG% is usually better because it increases all his damage, including his follow-up and ultimate. However, if you have a great HP% sphere with excellent sub-stats, it can be comparable. In general, go with Wind DMG% unless your HP% piece is significantly better.

How much HP does Blade need?

There’s no hard requirement, but a good target is around 6,000 to 7,000 HP. This ensures his damage is high and he can survive the HP loss from his skill and ultimate. With his signature light cone and Longevous Disciple set, reaching this is easy.

Does Blade need a healer?

Yes, absolutely. Blade consumes his own HP to use his skill and ultimate, and he takes damage to build his Charge stacks. Without a healer, he will quickly drop to critical HP. A healer like Luocha, Bailu, or Natasha is essential in any Blade team.

Can Blade work as a sub-DPS?

Yes, Blade can work as a sub-DPS, especially in teams with a primary DPS like Jingliu or Clara. He provides consistent damage and his follow-up attacks can trigger off ally HP loss, making him a great secondary damage dealer.
