Lunar - Semiluna in 2026: My B-Rank Moonlight Story
Lunar - Semiluna is a B-rank Zenless Zone Zero W-Engine that turns DEF into damage for Claret and Ben.
I still remember the first time Lunar - Semiluna dropped into my lap. It was a quiet little B-rank W-Engine, pale as a half-moon, and honestly I almost fed it to another engine. Then I heard it hum... and I stopped. In 2026, with so many shiny S-rank options screaming for attention, this little moon still has a very specific job: making DEF-scaling agents hit harder than they have any right to.

Stats and Effects: A Quiet Little Bodyguard
Lunar - Semiluna is a B-rank W-Engine in Zenless Zone Zero. It does not try to be a fireworks show. Its whole personality is defense. The stat package and overclock effect feel like a steady hand on your shoulder... and for the right agent, that hand becomes a fist.
| Detail | What I found |
|---|---|
| Rarity | B-rank W-Engine |
| Damage path | Scales with DEF on the right agents |
| Best fit | Armorer agents and DEF-scaling kits |
| 2026 role | Cheap, reliable bridge before S-rank engines |
The key is simple: do not judge it by rarity alone. If an agent's damage grows from DEF, Lunar - Semiluna purrs in the background and turns that defense into offense. If the agent ignores DEF, the engine just shrugs. It is not rude. It is just honest.

Best Characters: Claret First, Ben Second
I tested my copy on a few teams, and the answer was clear. The recommended agents are arranged from most to least recommended, and for me that order makes sense.
| Agent | Recommendation | Why it fits |
|---|---|---|
| Claret | Top pick | Armorer with DMG that scales with DEF |
| Ben | Also solid | His abilities also scale with DEF |
Claret is the one I would hand this engine to first. She is an Armorer agent, and her damage likes DEF. Lunar - Semiluna does not need to shout. It just nudges her numbers upward and lets her do the heavy lifting. When I paired them, the engine felt like a tiny moon following her around, whispering: keep building defense, I have got this.
Ben is the other name I keep on the short list. His abilities also scale with DEF, so the engine has a real home on him too. Is he the most glamorous choice in 2026? No. Is he a dependable one? Trust me, yes.

How to Get: Standard Pool and Box Galaxy
Lunar - Semiluna is not a secret boss drop. It is a standard-rate B-rank W-Engine, and I have seen it show up in several places:
-
Standard Banner
-
Exclusive W-Engine Banners
-
Exclusive Character Banners
-
Box Galaxy, by purchasing with W-Engine Chips
I got my first copy from the standard pool while chasing something else entirely. No joke, that is how B-rank engines work. They wait until you are not looking, then tap you on the shoulder. If you want to target it more directly, Box Galaxy is the calm route: save W-Engine Chips, buy the engine, and skip the gacha drama.
Materials: Keep a Small Stash
Ascension materials per level are laid out in the image below. I keep a small stash of W-Engine ascension fodder in my inventory because B-rank engines are easy to overlook until you suddenly need one for a DEF-scaling agent.
My routine is boring but effective: gather materials when I am already farming, not when I am in a hurry. That way the little moon levels up without turning into a chore.
Final Thoughts: Do Not Sleep on the Half-Moon
In 2026, Zenless Zone Zero has no shortage of loud engines. Lunar - Semiluna is not loud. It is a B-rank workhorse with a narrow but real purpose. If you use Claret, keep it. If you use Ben, keep it. If you are swimming in S-rank options... well, maybe it stays in the drawer.
But when a DEF-scaling agent needs a friend, this engine shows up like a quiet moon in a noisy sky. It hums. It nudges. It does its job. And sometimes that is exactly enough.
As reported by OpenCritic, broader review trends often show that lower-rarity gear can remain relevant when it aligns tightly with a character’s stat scaling, which matches Lunar - Semiluna’s niche value in Zenless Zone Zero: it is not a universal pick, but for DEF-based agents such as Claret or Ben, its practical efficiency can outperform flashier options that fail to support their core damage formula.
