Best Honkai Star Rail Asta build

Looking for the best Honkai Star Rail Asta build? Building Asta into your Honkai Star Rail squad is a perfect lesson in never turning your nose up at a free character in a gacha game. The inquisitive leader of the Herta Space Station is offered up as the first character you’ll roll for in the game’s warp tutorial, and by turning the heat up just a little with her, she can be baked into a mighty addition to any team in need of speed and attack buffs or break effectivity.

Getting the most out of what Honkai Star Rail gives you for free is important, so be sure to check our list of all Honkai Star Rail codes for wishing on the current and next banners. Alongside this, seeing where Asta lies on our Honkai Star Rail tier list will give you an idea of her viability, and help cement her as one of the best support characters right now.

What is the best Honkai Star Rail Asta build?

The best Asta build is:

• Light Cone – But the Battle Isn’t Over or Memories of the Past
• Relics – Thief of Shooting Meteor (four-piece set)
• Planar Ornaments – Talia: Kingdom of Banditry or Sprightly Vonwacq
• Eidolons – Moon Speaks in Wax and Wane
• Team comp – Asta, Seele, Bronya, Bailu

We’ve broken our picks down into individual sections below, each with handy context for how we’ve landed on the best Asta build.

Best Asta Light Cones

The best Asta Light Cones are:

• But the Battle Isn’t Over (five-Star)
• Memories of the Past (four-Star)
• Chorus (three-star)
• Meshing Cogs (three-Star)

Ideally, Asta should be built to accentuate her buffing ability, which is why we’ve gone for But the Battle Isn’t Over as a great five-star Honkai Star Rail Light Cone for her. While it may be ideal for Bronya, it also perfectly suits Asta’s needs for constant uptime on her speed-boosting ultimate too. Alternatively, you can build Asta into a break machine, which Memories of the Past offers in spades, albeit with lesser energy regeneration. 

Best Asta Relics

The best Asta Relics are:

From the early outset, Asta’s Meteor Storm skill sets her up to be a weakness-breaking powerhouse for any team. At its base level, it will hit random enemy targets five times helping to trigger her attack-boost talent, but when facing a lone, fire-vulnerable boss, her ability to weakness break skyrockets. As such, this easily acquired set does wonders for her break effectiveness.

Best Asta Planar Ornaments

The best Asta Planar Ornaments are:

Our first option, Talia: Kingdom of Banditry, will usually be the more popular choice as it provides Asta with additional break effect, which her multi-hitting skill does in spades. Her innate speed-increasing kit means you’ll always be getting the extra 20% and suits teams where she’s the only fire-aligned character with DPS being handled elsewhere.

We would suggest our second option, Sprightly Vonwacq, only in situations where you’ve got the fire weakness covered by another team member, which lets Asta focus on speed-tuning the team.

Best Asta Eidolon

The best Asta Eidolon is:

Thankfully, most of Asta’s Eidolon value comes pretty early. Moon Speaks in Wax and Wane allows Asta the chance to use her ultimate on any turn without dropping her highly valuable charging stacks on her allies, which boosts attack for the entire team by up to 40%(or more with Traces levelled). Allowing Asta to juggle both the massive speed increase from her ultimate and her attack-boosting passive is key to her viability.

Asta Ascension Materials

Asta’s Ascension Materials are:

• (Ascension only) Endotherm Chitin
• Destroyer’s Final Road
• Stellaris Symphony/Ancestral Hymn/Harmonic Tune
• Silvermane Medal/Silvermane Insignia/Silvermane Badges

Stellaris Symphony and Ancestral Hymns will be the tougher ones to grind out on lower difficulties of Calyx (Crimson) in the early game, so we would recommend saving any Undying Embers from your banner rolling and opting to grab any monthly Harmonic Tunes at the ember exchange. You can then simply synthesize the necessary materials until the more rewarding Calyxes become available later on.

Best Asta team comp

The best Asta team comp is:

• Seele – Main DPS
• Bronya – DPS Buffer
• Asta – DPS Buffer
• Bailu – Healer

While it may appear a little support-heavy on the face of it, the principle behind this Honkai Star Rail team comp is for Asta to support powerful team members that excel in their own roles. The speed bonus attached to her ultimate ensures that characters are likely to attack before enemies, and even take multiple actions per turn once they pass a certain threshold. Don’t be tempted to overlook Asta’s talent, which provides a 7% attack bonus to all allies that can be stacked up to five times.

While Seele is technically a single-target DPS, her Resurgence talent means she’s still capable of tearing through waves of enemies over the course of a single turn. This ability is made even more potent by Bronya, who can manipulate the turn order so that the best character to respond to the situation is always next to act. You’re unlikely to find yourself in dire straits with this Asta team comp – but if you do, we’ve tagged in Bailu to provide healing and revival.

Last but not least, the best Asta team comp offers an even spread of elements that can facilitate weakness break across a wide variety of enemies – particularly bosses, who are often susceptible to each of the elements represented by these Honkai Star Rail characters.

That’s everything you need to create the best Honkai Star Rail Asta build, which can easily sustain you across all equilibrium levels. The great thing is that you don’t even have to worry about gambling on Warps or performing any arduous rerolls for her since she’s absolutely free.
