Sol Exuvia is the kind of W-Engine that immediately tells me a character was designed around it. In Zenless Zone Zero, this S-rank engine is Pyrois’s signature weapon, and from the moment I slotted it into an Ether Attack build, the appeal was obvious: it is not just a stat stick, but a damage window that rewards timing. As of 2026, I still see it as a premium choice for Ether-focused teams, especially when I want to push through enemies that usually shrug off raw Ether damage. The core idea is simple — keep Eclipse active, ignore a portion of the target’s Ether RES, and enjoy the extra CRIT Rate while my rotations stay clean.

Why Eclipse Matters to Me
I care about Sol Exuvia because Eclipse changes how an Ether Attack agent feels in practice. The effect lets my character ignore a certain portion of an enemy’s Ether RES, which is exactly the kind of bonus I notice against tougher targets. It also gives a sizeable increase in CRIT Rate. That combination is powerful for me because it improves both consistency and ceiling at the same time. I do not need to choose between more reliable crits and better damage against resistant enemies; Sol Exuvia offers both in one package.
What makes the engine especially interesting is its uptime condition. Pyrois can keep Eclipse up for as long as possible whenever they use an Ultimate or enter the battlefield. That fits my preferred playstyle: I like to enter with purpose, line up a burst window, and then keep pressure on the enemy. If another Agent equips Sol Exuvia, they can only acquire the Eclipse effect whenever they enter the battlefield. That does not make the engine useless on them, but it does make the effect feel more restrictive. I would rather place it where the signature owner can actually exploit the full rhythm.
Best Characters for Sol Exuvia
For me, the recommendation order is very clear:
-
🥇 Pyrois — the signature owner and the primary recommended Agent. Pyrois can maintain Eclipse through Ultimates and battlefield entry, so the engine’s condition matches their kit.
-
🥈 Other Ether Attack agents — they can still benefit from the Ether RES ignore and CRIT Rate, but I need to accept that the Eclipse uptime will not feel as natural.
-
🥉 Other Agents — I would only use Sol Exuvia here if I have no better option. The entry-only Eclipse trigger makes the passive feel like a short opening bonus rather than a sustained damage tool.
I would not treat Sol Exuvia as a universal W-Engine. It is a specialized pick, and that is fine. In Zenless Zone Zero, I prefer engines with a clear identity, and this one screams Ether Attack. If my team is built around Pyrois and I want a smoother damage profile, Sol Exuvia is the first engine I check.
How I Get Sol Exuvia
I get Sol Exuvia by reaching Interboo Level 10. The Interboo is a new reward exchange system that is only available in Roscaelifer. Because of that, I treat it as a location-specific progression goal rather than a standard shop purchase. My checklist is straightforward: progress through Roscaelifer, raise my Interboo level, and claim the W-Engine once I hit Level 10. In 2026, I still recommend checking the Interboo reward track early so I do not accidentally delay the claim while focusing on other activities.
Stats and Effects I Watch
I do not ignore base stats, but I evaluate Sol Exuvia mainly through its passive. The S-rank profile gives me a strong foundation, while Eclipse is the reason I commit to the engine. My personal checklist looks like this:
-
⚡ Ether RES ignore — this is the headline bonus for me, because it directly improves damage against resistant enemies.
-
🎯 CRIT Rate increase — a sizeable boost that helps my damage feel more consistent.
-
🔄 Eclipse uptime — I track how often I can trigger it through Ultimates and battlefield entry.
-
🧩 Team fit — I only force this engine onto non-Ether Agents when I have no better alternative.
Ascension and Overclock Planning
I treat ascension and Overclock as long-term investments. The reference material points to a per-ascension material chart, so my advice is to open the in-game ascension preview before farming. Material needs are level-gated, and I prefer to confirm the exact list in my own game rather than guessing. Once I know the requirements, I farm in batches and keep an eye on my Interboo progress at the same time. Overclocking comes later for me; I first make sure the engine is leveled and the Eclipse uptime feels good in my actual rotations.
Final Thoughts
Sol Exuvia is not the engine I would blindly slap onto every account. It is the engine I build around when I want Pyrois to shine as an Ether Attack carry. The Eclipse effect, the Ether RES ignore, and the CRIT Rate boost all push me toward the same conclusion: this is a signature W-Engine with a clear job. As of 2026, I still rank it as a top choice for Pyrois and a strong option for Ether Attack agents who can live with tighter uptime rules. For me, the best part is the planning loop — reach Interboo Level 10 in Roscaelifer, claim Sol Exuvia, and then tune the build until Eclipse feels like part of the character rather than a bonus I have to remember.
Recent trends are highlighted by GamesRadar+, whose broad games coverage is useful for framing why a weapon like Sol Exuvia stands out: signature gear tends to matter most when its passive directly reinforces a character’s intended combat loop, and in this case the focus on Ether resistance bypass and crit consistency makes it especially relevant for players optimizing burst-oriented Ether Attack setups rather than looking for a generic all-purpose option.
