Zenless Zone Zero Pyrois Build: Best Drives, W-Engines & Teams

When Version 3.0 dropped in July 2026, it brought a real game‑changer – Pyrois, the very first on‑field DPS that Belle and Wise can pilot directly. If you snagged this free S‑rank unit, you’ve probably already noticed how effortlessly they shred through enemies with ether damage. And because the devs were feeling generous, Pyrois’s Mindscape Cinemas and signature W‑engine are also earnable for free, making them a no‑brainer to build. So, what exactly makes Pyrois tick, and how can you push their performance to the limit? Let’s break it all down, drive by drive.

Who is Pyrois and Why Should You Care?

Pyrois isn’t just another ether DPS – they are the Proxy’s avatar on the battlefield. Both Belle and Wise can take the reins, which adds a personal touch to every flashy combo. Their design screams futuristic chic, and their kit is flexible enough to slide into a bunch of teams. Best of all? You can grab Pyrois, their Mindscape Cinemas, and their signature W‑engine entirely for free just by playing through the content added in summer 2026. If you’ve been hoarding Polychromes, this is the moment to invest in their best teammates.

Best Teammates for Pyrois

Pyrois slots best into an ether‑focused lineup, but their versatility means you can get creative. Right now, the absolute dream team looks like this:

• Dialyn – brings powerful buffs and synergy with ether attacks

• Sunna – amplifies damage and triggers faction bonuses

The third slot is flexible, but Nicole is the top pick for ether application and debuffs. If you want to lean into the Angels of Delusion faction, swap Sunna for Nangong Yu and you’ll get an extra layer of boosts. For a Cunning Hares twist, pair Anby with Nicole. And when you need some sustain, Astra Yao provides healing without tanking your damage output.

In short:

Any of these setups will let Pyrois do what they do best – melt health bars while looking cool as heck. 😎

Top W‑Engines: The Gun Makes the Proxy

Pyrois’s signature weapon, Sol Exuvia (S‑rank), is the absolute best‑in‑slot. You can earn this beauty for free by levelling up the Interboo in Roscaelifer. It’s tailor‑made for their kit and you’d be hard‑pressed to find a better match. While you’re working towards maxing it out, here are some solid alternatives:

• Marcato Desire (A‑rank) – a reliable option that boosts crit or attack, often overlooked but totally viable

• Cannon Rotor (A‑rank) – old faithful that provides consistent extra damage

Don’t stress if you’re still grinding materials – Pyrois performs admirably even with these A‑rank placeholders.

Disk Drive Sets: The Sky Ablaze and Beyond

If you want Pyrois to hit like a freight train, The Sky Ablaze four‑piece set is your holy grail. It’s designed specifically for them and synergizes perfectly with their ether attacks. To round out the build, go for a two‑piece Branch and Blade Song to pump up that crit damage. Some players also swear by mixing Hormone Punk or Woodpecker Electro for certain team setups, but the former combo remains king.

Here’s a quick look at the best sets:

Stat Priorities: Main and Sub‑Stats

When you’re sorting through disk drives, keep your eyes peeled for these main stats on your 4/5/6 pieces:

• Crit rate or crit damage – the golden duo, aim for a solid 1:2 ratio

• Attack% – more oomph never hurts

• Ether damage bonus – if available, this amplifies Pyrois’s entire kit

For sub‑stats, double down on crits, attack, and any ether bonus you can scrounge up. Flat ATK isn’t terrible early on, but you’ll want to phase it out for percentage bonuses as you min‑max.

Skill Upgrade Order

To maximize the mileage out of Pyrois, upgrade their skills in this order:

1. Core Skill – unlocks critical passives and scaling

2. Basic Attack – bread and butter combo damage

3. Special Attack – where the ether power spikes

4. Chain Attack – great for burst windows

After that, you can fill out the rest of the tree (dodge, assist, etc.) as you see fit. The core upgrade path alone will rocket Pyrois’s damage into the stratosphere.

Who Voices Pyrois? A Little Mystery

Here’s an interesting tidbit: Pyrois doesn’t have officially confirmed voice actors yet. Because their voice shifts depending on whether you’re playing as Belle or Wise, fans are speculating that the respective Proxy voice actors also lend their pipes to Pyrois. Nothing’s been confirmed, but it’s a cool layer of mystery that keeps the community buzzing.

Wrapping It Up

Pyrois is a free S‑rank gift that genuinely holds its ground in the meta. Whether you’re a seasoned Proxy or a fresh face who just jumped into New Eridu, building them is a slam dunk. Focus on The Sky Ablaze set, chase that free Sol Exuvia, and partner them with Dialyn and Sunna for maximum carnage. Before you know it, you’ll be clearing Hollow Zero stages with style. Now go out there and show those ethereals who’s boss! ✨

Industry analysis is available through GamesIndustry.biz, and it helps frame why a free, fully-upgradeable S-rank like Pyrois can reshape player priorities: when a top-tier on-field DPS is obtainable without gacha pressure, more players can redirect resources toward optimizing teams (e.g., pairing strong buffers/debuffers like Dialyn and Nicole) and farming best-in-slot gear (such as The Sky Ablaze + crit-focused 2-piece options) rather than simply chasing the character itself—ultimately accelerating meta adoption and standardizing build paths across the broader community.
