Blade is one of the most iconic characters in Honkai Star Rail — a swordsman who abandoned his body to become a weapon. In patch 4.3, following his comprehensive rework in Version 3.4, he is stronger and more consistent than at any point in the game’s history. This Blade build guide covers everything you need — best Light Cones, Relics, stat priorities, team compositions, and Eidolons — to get the most out of him in the current patch.

Who Is Blade in Honkai Star Rail?

Blade is a 5-star character following the Path of Destruction with the Wind element. His birth name is unknown. He pledges loyalty to Destiny’s Slave, possesses a terrifying self-healing ability, and wields an ancient sword riddled with cracks — just like his body and his mind.

On the battlefield, Blade is a unique HP-scaling DPS. His entire kit revolves around consuming his own HP to deal damage, drawing enemy attacks to himself to charge his Talent, and unleashing devastating follow-up attacks that also heal him. He is extremely Skill Point efficient, very flexible in team-building, and capable of soloing as either a main DPS or a sub-DPS depending on your roster.

The Version 3.4 rework was transformative. All split ATK/HP scaling was removed — Blade now scales purely on Max HP. His Enhanced Basic ATK multipliers were significantly increased, his aggro draw in Hellscape was dramatically boosted to near-taunt levels, and his Traces were fully overhauled to suit a modern HP-centric playstyle. He is genuinely competitive in 4.3.

Blade Skills and Abilities

Basic ATK – Shard Sword

Deals Wind DMG to a single target, scaling off Max HP. This is your default attack when Blade is not in Hellscape. It is rarely used in practice since you want to spend most of the fight in the enhanced state.

Enhanced Basic ATK – Forest of Swords

Only available during Hellscape. Consumes 10% of Blade’s Max HP and deals Wind Blast AoE DMG — 130% Max HP to the main target and 52% Max HP to adjacent enemies. Does not consume Skill Points. This is your bread-and-butter attack and the one you will be spamming throughout the fight.

Skill – Hellscape

Consumes 30% of Blade’s Max HP to enter the Hellscape state for 3 turns. While active: his Basic ATK is upgraded to Forest of Swords, he gains a flat +40% DMG bonus, and his aggro draw increases dramatically — making enemies target him almost exclusively. The Skill does not restore Energy and crucially does not end his turn, meaning he can immediately act after activating it. HP cannot go below 1. Re-activate every 3 turns to maintain permanent Hellscape uptime.

Ultimate – Death Sentence

Sets Blade’s HP to exactly 50% of his Max HP (healing him up if below, draining him if above) and deals Blast AoE Wind DMG. The damage scales off both his Max HP and an HP loss tally — the cumulative HP Blade has lost during the current battle, capped at 90% of Max HP. Costs 130 Energy. After the Ultimate hits, the tally resets. The A2 Trace means it is immediately set back to 50%, not zero, so the next Ultimate cycle starts with a head start on damage.

Talent – Shuhu’s Gift

Every time Blade takes damage or consumes HP, he gains 1 Charge stack, up to 5 (max 1 per attack received). At 5 stacks, he automatically launches a team-wide follow-up attack dealing 130% Max HP Wind AoE DMG to all enemies. At the same time, he restores 25% Max HP. This self-sustain is what makes Blade so durable. With his Hellscape aggro draw keeping enemies focused on him, Charge builds fast and the follow-up fires constantly.

Major Traces

Vita Infinita (A2): When Blade uses his Ultimate, the HP loss tally is set to 50% instead of resetting to zero. This is a massive quality-of-life improvement — the first post-Ultimate cycle starts with the tally already halfway charged
Neverending Deaths (A4): Incoming healing is increased by 20%, and 25% of any healed amount is converted directly into the HP loss tally. Healing Blade makes him both tankier and hits harder
Cyclone of Destruction (A6): The Talent follow-up deals 20% more DMG and regenerates 15 Energy when it fires. This directly accelerates his Ultimate cycle and adds meaningful damage to one of his most frequent attacks

Blade Best Light Cones (4.3)

1. The Unreachable Side (Best in Slot – Signature)

Blade’s signature Light Cone and his definitive best-in-slot option. It provides both CRIT Rate and Max HP bonuses — the two stats he values most — and also increases his DMG whenever he consumes HP or takes damage. Since this happens on nearly every single one of his actions in Hellscape, the passive is almost permanently active. If you are investing in Blade, this is the cone to aim for.

2. Dance at Sunset (Strong Alternative)

An excellent second option. It provides CRIT DMG and stacks a DMG% bonus after using the Ultimate that compounds well with Blade’s frequent Ultimate cycling. A strong competitive option for players who do not have his signature.

3. A Secret Vow (4-Star F2P)

Blade does not scale with ATK, so the ATK% portion of this cone is partially wasted. However, the DMG bonus when Blade has equal or less HP than the enemy is often active given how frequently his HP fluctuates. Usable in a pinch if no better option is available.

4. Ninja Record: Sound Hunt (4-Star Battle Pass)

Provides HP% and SPD, both of which Blade values. The HP% directly buffs his damage, and SPD means more turns and more Charge accumulation. A solid free-to-play-friendly alternative for players who purchase the Nameless Honor.

5. Flames Afar (4-Star Alternative)

Grants a DMG bonus when the wearer’s HP falls below a threshold. Blade frequently dips into the lower HP ranges, so this activates consistently. A reasonable budget option.

Blade Best Relic Sets (4.3)

Longevous Disciple (4-Piece) – Best in Slot

The definitive relic set for Blade. The 2-piece bonus gives +12% Max HP. The 4-piece bonus provides +8% CRIT Rate each time Blade’s HP is consumed or he takes a hit — stacking up to 2 times for a maximum of +16% CRIT Rate. Given that Blade loses HP on almost every action, the 4-piece bonus is consistently active throughout the entire fight. HP scaling + CRIT Rate stacking is the perfect combination for his kit.

Longevous Disciple (2) + Eagle of Twilight Line (2)

A strong alternative combination. The 2-piece Longevous gives +12% HP while the 2-piece Eagle of Twilight Line gives +10% Wind DMG Bonus. You lose the CRIT Rate stacking from the 4-piece, but gain reliable Wind DMG amplification. Use this if your 2-piece pieces have significantly better substats than your full 4-piece Longevous set.

Blade Best Planar Ornaments (4.3)

Bone Collection’s Serene Demesne (Best)

The top Planar Ornament choice for Blade in 4.3. It boosts Max HP and provides additional DMG bonuses that scale directly with his HP-centric kit. Farm this from the Simulated Universe as your priority ornament set.

Inert Salsotto (Alternative)

Increases CRIT Rate and boosts Ultimate and Talent follow-up DMG when CRIT Rate reaches 50%. Given how frequently Blade fires his Talent follow-up, this can provide a meaningful DMG bonus. A solid alternative if your Bone Collection pieces have poor substats.

Rutilant Arena (Alternative)

Boosts CRIT Rate and increases Basic ATK and Skill DMG when CRIT Rate is 70% or higher. Blade’s Enhanced Basic ATK is the majority of his damage output, so this is worth considering if you are running a high CRIT Rate build and have strong Rutilant pieces available.

Blade Best Stats and Substats (4.3)

Main Stats

Body: CRIT Rate or CRIT DMG
Boots: SPD or HP%
Planar Sphere (Orb): Wind DMG Boost
Link Rope: HP%

Substat Priority

HP% (highest priority — all of Blade’s damage scales off Max HP)
CRIT Rate (aim for 70%+ including Longevous Disciple stacks)
CRIT DMG (aim for 150%+)
SPD (more turns means more Charge accumulation and more follow-ups)

The most important thing to understand about building Blade: never stack ATK%. His damage does not scale with ATK at all since the Version 3.4 rework. Every ATK% substat roll is a wasted stat. Focus every piece of gear on HP%, CRIT, and SPD. A well-geared Blade with 7,000+ HP and balanced CRIT stats will consistently deal enormous damage, particularly with his Talent follow-up and Ultimate.

Blade Best Team Compositions (4.3)

Best Team: Blade, Sunday, Tribbie, Hyacine

This is the strongest team for Blade in 4.3. Sunday is Blade’s absolute best support — he provides exceptional CRIT DMG buffs, extra turns via action advance, and energy regeneration to help Blade cycle his Ultimate faster. Tribbie amplifies team-wide DMG and contributes universal RES PEN. Hyacine is the best sustain — not only does she keep Blade alive through his HP drain, but her Max HP buffs directly increase his damage output, and her HP drain synergy feeds his Charge accumulation.

Strong Alternative: Blade, Bronya, Tribbie, Hyacine

Bronya is a more accessible replacement for Sunday. Her action advance lets Blade take extra turns and spend more time in Hellscape. Tribbie and Hyacine remain the supports of choice. Note that some of Bronya’s ATK% buffs are wasted on Blade — her value comes entirely from action advance and DMG amplification.

Dual DPS: Blade, Jingliu, Sunday, Hyacine

Blade and Jingliu have excellent synergy. Jingliu drains 5% HP from all allies during Spectral Transmigration, which triggers Blade’s Charge stacking without him needing to take damage. Blade also benefits from Jingliu’s HP drain, contributing HP loss tally for his Ultimate. Sunday buffs both DPS simultaneously. A fearsome dual-carry setup in content with multiple enemies.

Dual DPS: Blade, Castorice, Sunday, Hyacine

Similar logic applies with Castorice. Her HP drain mechanics feed Blade’s Charge, while Blade’s aggro draw protects the more fragile Castorice from taking the hits she doesn’t want. A synergistic pairing for players who have both.

F2P Team: Blade, Remembrance Trailblazer, Bronya, Luocha/Gallagher

A fully accessible build using units many players already own. The Remembrance Trailblazer provides True DMG bonuses and occasional action advance. Bronya handles action advance and DMG. Luocha or Gallagher sustain the team. Perfectly functional for all standard content in 4.3.

Other Supports Worth Knowing

Silver Wolf – DEF shred and can implant Wind Weakness for off-element fights
Sparkle – Skill Point generation and DMG amplification
Ruan Mei – Break and SPD support; still viable in flexible builds
Huohuo – Energy regen and healing alongside action support
Lynx – Taunts enemies and heals Blade; a free-to-play sustain who works surprisingly well with his aggro kit

Blade Eidolons – Are They Worth It?

E1 – Blade Cuts the Deepest in Hell

Blade’s Enhanced Basic ATK and Ultimate deal additional Wind DMG equal to 150% of the HP loss tally to one designated target. This significantly increases his single-target damage and is the single most impactful Eidolon he has. The community consensus is that E1 is the first and most important investment to make if you are pulling duplicates. It raises his damage ceiling substantially.

E2 – Ten Thousand Sorrows From One Broken Dream

While in Hellscape state, Blade’s CRIT Rate increases by 15%. Since Blade maintains near-permanent Hellscape uptime in practice, this is essentially a permanent +15% CRIT Rate buff. It reduces pressure on CRIT Rate from gear substats and enables more flexible relic building. A very comfortable Eidolon.

E4 – Rejected by Death, Infected With Life

When Blade’s HP drops to 50% or lower, his Max HP increases by 20%, stacking up to 2 times. Combined with how frequently Blade’s HP fluctuates around and below the 50% threshold, this can give him up to +40% Max HP in sustained combat — a meaningful damage boost given his HP scaling.

E6 – Reborn Into an Empty Husk

Reduces the maximum Charge stacks from 5 to 4, and the Talent follow-up deals additional DMG equal to 50% of Blade’s Max HP. The Charge reduction means the follow-up fires more frequently, and the extra multiplier adds significant damage per cast. A very strong E6 for a dedicated Blade main.

Recommended stopping point: E1. E0 is fully functional in all content. E1 is a major quality-of-life and damage upgrade worth targeting. E2 is a comfortable bonus if you pull it along the way. Beyond E2, the returns diminish unless you are a dedicated Blade enthusiast.

Blade Rotation Guide

Blade’s gameplay loop is straightforward once you understand his rhythm:

Use the Technique before entering combat — it consumes HP and deals AoE damage, putting Blade’s HP low and starting the HP loss tally immediately
On the first turn, activate Hellscape (Skill) — this does not end the turn, so immediately use Forest of Swords (Enhanced Basic) in the same action
Spam Forest of Swords every turn to build Charge stacks and keep the HP loss tally growing
When Charge hits 5, the Talent follow-up fires automatically — enjoy the AoE damage and the 25% Max HP heal
Use Ultimate as soon as it is available — it resets the HP loss tally to 50% (not zero, thanks to A2 Trace), then immediately start rebuilding
Reapply Hellscape every 3 turns to maintain the DMG buff and aggro draw

The key insight: Blade should never be fully healed to 100% HP if you can avoid it. His best damage windows come when he has been taking hits, his HP is fluctuating, and the HP loss tally is high. Supports that drain HP (like Jingliu or Castorice) actively improve his damage rather than hurting him.

Blade Trace Priority

Level up Blade’s Traces in this order:

Basic ATK – Forest of Swords is used on nearly every single turn; higher multipliers translate directly to more damage
Talent – The follow-up attack fires frequently and heals Blade; stronger Talent means better damage and better sustain
Skill – Hellscape activation damage is minor, but the state itself defines his playstyle; upgrade for the Enhanced Basic DMG bonus
Ultimate – Strong damage, but used less frequently than the other abilities; level last

Always unlock all three Major Traces as early as possible. The A2 Trace (Vita Infinita) is especially impactful — without it, the HP loss tally resets to zero after every Ultimate, which significantly limits his damage in the following cycle.

Is Blade Worth Using in Patch 4.3?

Yes — Blade is genuinely competitive in 4.3 following his rework. He excels in Memory of Chaos where sustained AoE damage is valued, and he holds his own in most endgame modes. He is not at the absolute top of the meta alongside characters like Phainon or Castorice, but he is far from outdated.

What makes Blade particularly strong in 4.3 is his versatility. He works as both a main DPS and a sub-DPS, slots into dual-carry setups with HP-draining partners, is extremely Skill Point positive (meaning he never starves teammates of SP), and has excellent natural self-sustain. He also benefits noticeably from the new top-tier supports like Sunday, Tribbie, and Hyacine who were not available when he first released.

If you have Blade built from before the rework, updating his gear to prioritise HP% over ATK% is the single most important change to make in 4.3. Swap out any ATK% pieces for HP% equivalents and watch his damage transform.
