Honkai Star Rail Trailblazer build for all paths

Honkai Star Rail’s Trailblazer is a versatile member of the Express crew. Discover their best build, relics, light cones, and more below.

Honkai Star Rail Trailblazer: Stelle and Caelus with Mem on an ice PT background

Introducing the Honkai Star Rail Trailblazer, our vessel for joining the crew of the Astral Express and saving the universe from Stellarons. But who exactly is the HSR Trailblazer? What are their skills, and what’s the best build for them? We’re here to answer all these questions for you.

We’ve got plenty of trailblazing guides for you to study up on including a Honkai Star Rail tier list, a guide to the Honkai Star Rail next banner, and a list of Honkai Star Rail codes. There are also build guides for more of our crewmates like Honkai Star Rail’s Feixiao, Honkai Star Rail’s Moze, and Honkai Star Rail’s Lingsha.

Here’s everything in our Honkai Star Rail Trailblazer build:

What’s the best Honkai Star Rail Trailblazer build?

The Trailblazer is an adaptive character, meaning you can align them with different paths and elements as you progress through the story. So far, we’ve seen the Trailblazer aligned with the path of Destruction, the path of Preservation, and most recently, the path of Harmony.

When aligned with the path of Destruction, the Trailblazer’s kit is all about hitting hard with physical damage that scales off of their attack stat. They have both single attack and blast options so they’re a great all-round attacker for big bosses or groups of enemies. We recommend putting your resources into raising their attack stat and physical damage capabilities.

When aligned with the path of Preservation, the Trailblazer dishes out heavy hits that deal fire damage. Their normal attack triggers a shield for the whole team while also hitting the enemy with a single strike, whereas their skill sees them plant their weapon in front of them, creating a shield for the team and taunting enemies to focus attacks on them instead of their allies. Their ult also triggers the team-wide shield, while dishing out AoE fire damage to all enemies.

When aligned with the path of Harmony, the Trailblazer provides break effect buffs to their team while also dealing imaginary damage. Their skill deals spread imaginary damage across the field and their ultimate massively increases all allies’ break effect, while introducing Super Break damage. Focus on building their HP and defense for survivability as their break effect buffs are super powerful.

When aligned with the path of Remembrance, the Trailblazer summons a helpful Memosprite called Mem onto the field and can buff allies’ crit damage. Summoning Mem to the field advances one ally’s action and allows them to deal True damage – a new type of damage similar to Super Break.

What are the best light cones for the Trailblazer?

Destruction Trailblazer light cones

If you can’t get a hold of Something Irreplaceable or On the Fall of an Aeon, our three-star recommendation is Collapsing Sky. Or you can use any that follow the path of Destruction.

Something Irreplaceable (five-star) Increases the Trailblazer’s attack by 24%. After receiving an attack, you immediately restore HP equal to 8% of your attack and increase damage dealt by 20%. This effect is valid until the end of the Trailblazer’s turn. The effect cannot stack and can only trigger once per turn Gacha
On the Fall of an Aeon (five-star) Whenever the Trailblazer attacks, it increases their attack by 8% up to four times. When you inflict weakness break on enemies, your damage increases a further 12% for two turns Herta’s Store
Under the Blue Sky (four-star) Increases the Trailblazer’s by 16%. When the Trailblazer defeats an enemy, their crit rate increases by 12% for three turns Gacha
Collapsing Sky (three-star) Increases Trailblazer’s basic attack and skill damage by 20% Gacha

Preservation Trailblazer light cones

For Preservation Trailblazer, we recommend the Texture of Memories light cone from Herta’s Store or Honkai Star Rail Gepard‘s Moment of Victory Light Cone. Of, for a four-star option, we recommend Day One of My New Life or Landau’s choice. If you don’t have any of these to hand or want to try something different, just make sure that it also aligns with the path of Preservation.

Texture of Memories (five-star) Increases the Trailblazer’s effect resistance by 8%. If an enemy attacks the Trailblazer when they don’t have a shield, they gain a shield equal to 16% of their max HP for two turns. This effect can only trigger once every three turns. If the Trailblazer has a shield when they’re attacked, the damage they receive decreases by 12% Herta’s store
Moment of Victory (five-star) Increases the Trailblazer’s defense by 24% and effect hit rate by 20%. Also increases the chance that enemies will attack the Trailblazer. When an enemy attacks the Trailblazer, their defense increases by an additional 24% until the end of their turn Gacha or the Starlight Exchange store
Day One of My New Life (four-star) Increases the Trailblazer’s defense by 16%. After entering battle, also increases the damage resistance of all allies by 8%. Effects of the same type can’t stack Gacha
Landau’s Choice (four-star) The Trailblazer is more likely to be attacked, but the damage they take reduces by 16% Gacha

Honkai Star Rail's Trailblazers with the crew of the Astral Express

Harmony Trailblazer light cones

Harmony Trailblazer’s best light cone for break effect is Past Self in Mirror, Honkai Star Rail Ruan Mei‘s signature five-star cone. No other cones compare when it comes to this stat, but you’ll need to supplement the Trailblazer’s energy regeneration with a link rope if you use it before reaching E6.

A great four-star option is Memories of the Past, as it’s easier to obtain than Past Self and has better energy regeneration stats, replacing the five-star cone’s team-wide damage buff. Using this cone also lets you equip a break effect link rope to compensate. If you’re really struggling for energy regeneration and just want to keep the Trailblazer’s ultimate live, a fully-upgraded Meshing Cogs light cone is a fantastic budget pick.

Past Self in Mirror (five-star) Increases the Trailblazer’s break effect by 60%. When the Trailblazer uses their ultimate, increases all allies’ damage by 24%, lasting for three turns. Should the Trailblazer’s break effect exceed or equal 150%, recover one skill point. At the start of each wave, all allies regenerate ten energy immediately. Effects of the same type cannot stack Limited gacha alongside Ruan Mei
Memories of the Past (four-star) Increases the Trailblazer’s break effect by 28%. When the Trailblazer attacks, additionally regenerates four energy. This effect cannot be repeatedly triggered in a single turn Gacha
Meshing Cogs (three-star) After the Trailblazer uses attacks or gets hit, additionally regenerates four energy. This effect can only be triggered once per turn Gacha

Remembrance Trailblazer light cones

As this path is brand new, we don’t have many light cone options just yet. We recommend using Victory In a Blink, the four-star Remembrance light cone, as it is free-to-play friendly and offers a crit damage buff.

Victory In a Blink (four-star) Increases the Trailblazer’s crit damage by 12%. When the Trailblazer’s memosprite uses an ability on an ally target, increases the damage dealt by all ally targets by 8%, lasting for three turns Mission reward or bought from Light Cone Manifest
Shadowburn (three-star) When the Trailblazer summons memosprite for the first time, recovers one skill point and regenerates 12 energy for this unit Gacha

What are the best relics for the Trailblazer?

Destruction Trailblazer relics

The best Honkai Star Rail relics for the Destruction Trailblazer so far are those that increase physical damage and attack. Champion of Streetwise Boxing is perfect for this but also one of the starting relic sets that you encounter, Musketeer of Wild Wheat, does almost as good a job and is much easier to find than other options.

As they’re a hard-hitting DPS unit, the Destruction Trailblazer’s best planar ornament set is Rutilant Arena, but you can use Space Sealing Station during the early game as it is one of the easier sets to get in the Simulated Universe.

Champion of Streetwise Boxing Two equipped: increases physical damage by 10%
Four equipped: after the Trailblazer attacks or is hit by an enemy, their attack increases by 5% for the rest of the battle. This effect can stack up to five times
Cavern of Corrosion: Path of Jabbing Punch in Jarilo-VI’s Everwinter Hill
Musketeer of Wild Wheat Two equipped: increases attack by 10%
Four equipped: increases the Trailblazer’s speed by 6% and their basic attack damage by 10%
Cavern of Corrosion: Path of Drifting in Jarilo-VI’s Corridor of Fading Echoes

Planar ornaments

Space Sealing Station Two equipped: increases the Trailblazer’s attack by 12%. When their speed reaches 120 or higher, their attack increases by another 12% Immersion Reward devices in World 3 of the Simulated Universe, or Divergent Universe: Untoppled Walls
Rutilant Arena Two equipped: increases the Trailblazer’s crit rate by 8%. When the Trailblazer’s current crit rate reaches 70% or higher, their basic attack and skill damage increase by 20% Immersion Reward devices in World 7 of the Simulated Universe, or Divergent Universe: Fruit of Evil

Destruction Trailblazer relic stat recommendations

Main stats:

  • Body: crit rate/damage
  • Feet: speed or attack
  • Planar sphere: physical damage bonus or attack
  • Link rope: attack or break effect

Sub-stats:

  • Crit rate
  • Crit damage

Preservation Trailblazer relics

When aligned with the path of Preservation, the best relic set for the Trailblazer is Knight of Purity Palace. You can run it as a four-piece set for maximum shield buffing, or pair it with Messenger Traversing Hackerspace for some additional speed. If you want to buff their personal damage, try Firesmith of Lava Forging instead.

If you’re still struggling with defense stats for the Trailblazer, we recommend using Belobog of the Architects as your planar ornament set, but there are better sets available. Broken Keel increases their effect resistance to prevent debuffs and can trigger a team-wide crit damage increase, and Fleet of the Ageless gives the Trailblazer more survivability while also unlocking an attack buff for the team if their speed is high enough.

Firesmith of Lava Forging Two equipped: increases fire damage by 10%
Four equipped: increases the Trailblazer’s skill damage by 12%. After unleashing an ultimate, the Trailblazer’s next attack deals an additional 12% fire damage

Planar ornaments

Belobog of the Architects Two equipped: increases the Trailblazer’s defense by 15%. When their effect hit rate is 50% or higher, they gain an extra 15% defense Immersion Reward devices in World 6 of the Simulated Universe, or Divergent Universe: Permafrost
Broken Keel Two equipped: increases the Trailblazer’s effect resistance by 10%. When the Trailblazer’s effect resistance is at 30% or higher, all allies’ crit damage increases by 10% Immersion Reward devices in World 7 of the Simulated Universe, or Divergent Universe: Fruit of Evil
Fleet of the Ageless Two equipped: increases the Trailblazer’s max HP by 12%. When the Trailblazer’s speed reaches 120 or higher, all allies’ attack increases by 8% Immersion Reward devices in World 3 of the Simulated Universe, or Divergent Universe: Untoppled Walls

Harmony Trailblazer relics

Choosing the right relics for the Harmony Trailblazer is all about balancing their two best stats: speed and break effect. The optimal break effect relic loadout is four pieces of Watchmaker, Master of Dream Machinations thanks to its personal and team-wide break effect buffs.

Thief of Shooting Meteor and Messenger Traversing Hackerspace are fantastic flexible sets that you can either pair together for a combination of speed and break effect buffs, or combine with a two-piece set of Watchmaker for a similar stat spread. Thief and Watchmaker is the best combination to increase the Trailblazer’s personal break effect.

For planar ornaments, choosing Talia: Kingdom of Banditry is a no-brainer. Its effect provides even more break effect stats and you’ll almost always trigger its secondary effect thanks to the Trailblazer’s impressive speed. If you’re struggling for energy regeneration in certain builds, you can swap this out for Sprightly Vonwacq. 

You can also make a case for running Forge of the Kalpagni Lantern on the Trailblazer if you’re pairing them with Honkai Star Rail’s Firefly or going up against a lot of fire-weak opponents. Its effect is more conditional than other planar ornaments, but the whopping 40% break effect increase is more than worth it.

Watchmaker, Master of Dream Machinations Two equipped: increases break effect by 16%
Four equipped: when the Trailblazer uses their ultimate on an ally, all allies’ break effect increases by 30% for two turns. This effect cannot stack

Sub-stats:

  • Speed

  • Effect resistance

Remembrance Trailblazer relics

The Remembrance Trailblazer’s current best-in-slot relic set is four pieces of Hero of Triumphant Song. This is the only relic set in the game currently that specifically buffs Remembrance characters, and it increases their speed and crit damage.

Alternatively, you can run a combination of Messenger Traversing Hackerspace and Sacerdos’ Relived Ordeal for a double speed buff so that the Trailblazer can get Mem onto the field as quickly as possible.

If you can get their speed above 120, the best planar ornament set for the Remembrance Trailblazer is Sprightly Vonwacq. This helps them to advance in the turn order and activate Mem even faster. Broken Keel is also a great choice for a team-wide crit damage buff if you can meet the effect resistance requirements.

Hero of Triumphant Song Two equipped: increases attack by 12%
Four equipped: while the Trailblazer’s memosprite is on the field, increases their speed by 6%. When the Trailblazer’s memosprite attacks, increases their and Mem’s crit damage by 30%, lasting for two turns

What’s the best Trailblazer team comp?

As with Genshin Impact’s Traveler, the Trailblazer is a de facto five-star character who can slot into a bunch of team comps, especially as the path system gives them different set roles. Each of the available paths is strong in its own right, but often works as a substitute for other limited five-stars rather than as a must-pick unit.
