Buy Lunar Crystal for Duet Night Abyss: packs, the Lunotress Monthly Pass and Myriad cosmetics
Duet Night Abyss is a free-to-play open-world action RPG from Hero Games, an independent Shanghai publisher, and its in-house Pan Studio. The global launch landed on 28 October 2025 across iOS, Android and PC via the in-house launcher and the Epic Games Store, with a Steam release added on 20 January 2026 that auto-syncs existing progress. As of May 2026 the live build is Version 1.3 "The Firmament Unbound", which closes the Huaxu arc and adds the Taixu Rover flying-sword mount. The premium currency is Lunar Crystal, and it funds seasonal cosmetics, the monthly pass and the Myriad cosmetic gacha.
- Six Lunar Crystal denominations: 60, 300, 980, 1980, 3280, 6480
- First-purchase x2 bonus on each denomination separately
- In-game exchange of Lunar Crystal into Phoxene Plumules for Myriad pulls
- Lunotress's Monthly Pass: 300 Phoxene Plumules instantly plus 90 daily for 30 days
- Seasonal cosmetic and material bundles
- Top-up by Character ID — no login needed
What sets Duet Night Abyss apart from its genre neighbours
Six months before launch Pan Studio announced that they were cancelling the character and weapon gacha — the 50/50 banners and star-rarity rating on heroes are gone. Every playable character and every weapon now unlocks for free through the campaign, events and crafting. The studio also removed the stamina cap on dungeon farming, which is unusual for the genre. Lunar Crystal stays in, but the economy tilts toward cosmetics and seasonal bundles: the "save up for the next rerun" pressure familiar from other open worlds is not the way this game is monetised.
The Myriad cosmetic gacha: what banners are still in
Despite the dropped character gacha, the game keeps a cosmetic banner system called Myriad, which rolls character skins, weapon skins and accessories. The numbers: a single pull costs 160 Phoxene Plumules or 160 Phoxene, the gold drop rate is 0.3%, hard pity for a gold sits at 90 pulls, and a purple is guaranteed every 10 pulls. There are two banner types — Limited-Time Myriad and the permanent Starlight Rondo. One detail trips up new players: each banner uses its own Hourglass currency — Prismatic Hourglass for the limited and Pristine Hourglass for the permanent — and they are not interchangeable. Pity tracks separately on each banner with no carry-over between Limited and Permanent.
Lunotress's Monthly Pass: where the slow-burn value sits
Lunotress's Monthly Pass is the project's main subscription. On purchase it pays out 300 Phoxene Plumules instantly and then 90 Phoxene Plumules daily for 30 days, totalling 3,000 Plumules per cycle if you log in every day. Structurally it resembles 30-day passes from neighbouring gacha titles, but it is tied directly to Myriad's pull currency: the people who get the most out of it are players who plan to roll cosmetic banners. Pan Studio has not publicly confirmed stackable behaviour for the pass, so plan around a single active subscription rather than running two in parallel.
Phoxene Plumules and why the catalogue lists Lunar Crystal
Phoxene Plumules show up in FAQs and search queries, and the distinction matters: Phoxene Plumules are an in-game pull currency obtained by exchanging Lunar Crystal at the in-game shop. They are not sold directly through top-up storefronts — what you buy on the catalogue is Lunar Crystal at the denomination you need, and inside Duet Night Abyss you convert it into Plumules for Myriad or into Phoxene for upgrades. The reverse path (Phoxene back to Plumules) does not exist, so plan the split before confirming the trade.
Combat and dual protagonist — what Lunar Crystal actually buys
Combat in Duet Night Abyss is built on a melee + ranged hybrid: every character carries a melee weapon (greatsword, whipsword) and a firearm (pistol, shotgun, assault rifle) at the same time and switches between them on the fly. The combo style and parry mechanics draw frequent comparisons to Devil May Cry 5 — those come from the community, not from the developer's own positioning. The story is told through two protagonists, Phoxhunter (Vita by default) and The Boy/Girl in the Dream (Mors by default); the gender of each is chosen independently at creation. Because characters unlock for free, real money goes into presentation: Myriad skins, seasonal cosmetic bundles and the Lunotress pass.
Version 1.3 "The Firmament Unbound" and what May 2026 looks like
Since 7 April 2026 the game has been on Version 1.3 "The Firmament Unbound", the final chapter of the Huaxu arc. The patch opens five new regions (Outer Peaks, Youlai Alley, Taixu Mausoleum, Hall of Adjudication and the capital Haojing), the Taixu Rover flying mount, four new firearms and a theme song called "Binary Fate" by Tiger Hu. The Grand Incense Rite event has been live since 23 April. The new playable character Camilla arrives on 5 May 2026 — like every other character she does not need to be pulled, but her cosmetic skins will route through Myriad. Version 1.4's release window is not yet announced.
Servers, Character ID and how the top-up reaches the account
Duet Night Abyss runs on five regions: Europe, America, Asia, SEA and HMT. SEA sitting next to Asia as a separate server is something players coming from four-server titles often miss. The server is chosen at character creation and cannot be changed — moving regions means a brand-new account. Character ID is the numeric identifier shown on the in-game profile card when you tap the avatar in the main menu (under your name, next to the server label). Cross-progression is total: PC, iOS and Android have shared a single account since October 2025, and the Steam client links into an existing profile from January 2026 with no progress reset. Lunar Crystal is delivered against the Character ID and server combination, so no login is needed at top-up.
- Open Duet Night Abyss and copy the Character ID from your profile card.
- Pick the Lunar Crystal pack or the Lunotress's Monthly Pass from the catalogue.
- Enter the Character ID and the server (Europe / America / Asia / SEA / HMT).
- Review the data on the checkout screen and complete payment.
- Wait for delivery — Lunar Crystal lands on the linked Character ID.
Platforms, language support and the Steam reception
As of May 2026 Duet Night Abyss runs on Windows PC (Steam, Epic, in-house launcher), iOS and Android. There is no console version: the studio has stated interest in PS5 and Xbox Series, but no dates have been announced, and PS4, Xbox One, Switch and macOS are not supported. Official language support covers English, Japanese, Korean and Chinese (Simplified and Traditional); other languages are not available natively. The Steam launch on 20 January 2026 met Mixed reviews (about 58% positive): a vocal slice of reviewers takes issue with Myriad as a contradiction of the "no gacha" marketing, so treat the no-gacha headline with the cosmetic-banner caveat in mind.
