When you think about a gacha game likeHonkai: Star Railwhere you can spend real money to get certain characters, you’d think that the best abilities are locked behind these limited characters. However, the developers consistently prove this wrong by releasing various phenomenal free-to-play friendly characters.
The best example of this would be the Harmony Trailblazer, which is a completely free unit that every player can get through the main story. This unit isn’t too difficult to build and gives you a lot more value than you’d expect.

Best Harmony Trailblazer Relics And Planar Ornaments
Finding good sets for the Harmony Trailblazer might’ve been difficult during the early stages of Honkai: Star Rail, but the game isalready prepared for theunit on release during the Version 2.2 update. Here are some of the best bonuses you’re able to get;
Relics
Watchmaker, Master Of Dream Machinations
Gives Trailblazer some extra Break Effect while increasing theentire party’s Break Effect by another 30 percent upon using Ultimate. This stacks with the Break Effect you’re able to get from the Ultimate itself.
Thief Of Shooting Meteor
Apart from increasing Trailblazer’s Break Effect by 32 percent, this set also gives them extra Energy upon triggering Weakness Break. It’sgreat if you’re planning to trigger breaks with this unit.
Messenger Traversing Hackerspace
This is a more generic set that gives Trailblazer some SPD whilealso increasing the SPD of all alliesafter the Ultimate.
Planar Ornaments
Penacony, Land Of The Dreams
This is the BIS set for Harmony Trailblazer if you’replanning to use them with another Imaginary DPS unit. It gives them some extra Energy Regeneration while also buffing the DPS in question.
Talia: Kingdom Of Banditry
In all other instances, you’d want to use this set on the Trailblazer andtry to reach the high SPD threshold required for it.
Harmony Trailblazer Relic Stat Priority
Much like various other Harmony units, you wouldn’t have a hard time building Harmony Trailblazer. However, it can be alittle difficult if you get unlucky with a certain stat:
Break Effect
SPD > ATK Percent > HP/DEF Percent
HP or DEF Percent main stats are recommended wherever possiblejust to make the Trailblazer as tanky as possible.
However, if you want to look for some damage on their Skill or Basic Attack, you can go for ATK or Crit main stats as well.

Best Harmony Trailblazer Light Cones
Once you’ve reached the part in the story where you may acquire Harmony Trailblazer,you’ll have more than enough Light Cone options for them. The main idea is to have as much Break Effect as you can, and then look for general buffs for your allies. Here’s how each Light Cone on this list helps with that:
Past Self In Mirror
This is a limited five-star Light Cone, but if you have it, it can give you a whopping 60 percent Break effect at Superimposition One. Other than that, it also boosts your allies' DMG after the Ultimate and regenerates some Energy.
Flowing Nightglow
If you’re building a pseudo-DPS build on the Trailblazer with ATK and Crit, you can use thisLight Cone to gain some extra Energy and ATKwhile giving your allies the same DMG bonus as the above Cone.
Memories Of The Past
Going down to the four-star choices, Memories of the Past will beyour best bet because of its massive Break Effectand extra Energy at Superimposition Five.
Planetary Rendezvous
Similar to the Penacony ornament set, if you’re usingHarmony Trailblazer with another Imaginary DPS, this Light Cone can be decent.
Dance! Dance! Dance!
This Cone advances your allies' actions after using the Ultimate, which isarguably the best effect on Trailblazerafter the Break Effect.
Carve The Moon, Weave The Clouds
Finally, this Light Cone is quite generic and itcan be used on any Harmony unit out therebecause of the various buffs it provides.
Harmony Trailblazer Trace Priority
Before deciding on your Relics and Light Cones, you’ll have to decidewhere and how many resources you want to invest in Harmony Trailblazer. Being a support unit, you’d want to be as efficient as possible unless you enjoy their play style enough to maximize everything. However, Harmony main character’s traces can be a little difficult to understand.
While their Basic Attack and Skill are straightforward, the Ultimate can be troubling. Essentially, once you activate your Ultimate, you deal extra damage to enemies that have their weakness broken. This damage is calculatedbased on the Break Effect of the attacking character and the Toughness Reducing DMGthat the respective attack would do.
This also applies to AoE-based damage, which means thatyou can deal three instances of Super Break DMGif you attack three Weakness Broken enemies at the same time.
After knowing all this, it’d be easy to figure out thatTrailblazer’s Ultimate will be your first choice of upgrade. you’re able to follow that up with the Talent and then upgrade the Skill a bit. You’ll have to get a higher level on the Skill if you’re planning to have the DPS build on them. However, you don’t have to upgrade the Basic Attack at all.
